Ant tasks for managing repositories
|
Specifying source repositories
|
|
Several p2 tasks accept "source" repositories. Source repositories can be specified in several different ways:
- A
source
attribute directly on the ant task. The value is a URL to a location that contains both a metadata and artifact repository. For example:
<p2.mirror source="https://download.eclipse.org/releases/galileo" .... />
- A
<source>
element nested in the ant task. This element is an ant fileset, with additional location and kind attributes.
-
location : A URL specifying the location of a repository. If this attribute is set, all fileset based attributes are ignored.
-
kind: Either "metadata" or "artifact". If not set, the repository is both metadata and artifacts.
If no location attribute is set, all directories matched by the fileset are added as repositories and all *.zip files are treated as zipped repositories
(accessed using a jar: URL). For example:
<source kind="metatata" dir="/build/input" includes="*.zip" />
<source location="https://download.eclipse.org/releases/galileo" />
- A
<source>
element containing a list of repositories. Each nested element is again a fileset with an additional kind attribute. For example:
<source>
<repository location="https://download.eclipse.org/releases/galileo" />
<repository kind="metadata" file="/build/repos/cdt-master-6.0.0-I200903161435.zip" />
<repository kind="artifact" dir="/build/repos" includes="*repo" />
</source>
|
|
Specifying destination repositories
|
|
Several p2 tasks accept "destination" repositories. Destination repositories can be specified in several different ways:
- A
destination
attribute directly on the ant task. The value is a URL to a location for both a metadata and artifact repository.
- A
<repository>
element nested in the ant task. (
<destination>
may also be used.)
This element supports the following attributes:
|
location
|
A URL to the location of the repository |
|
kind
|
Either "metadata" or "artifact". Default is both if not specified. |
|
name
|
A name to give the repository if the repository does not already exist. |
|
append
|
Append to a repository that is already there. (Default is "true") |
|
compressed
|
Whether to compress the content/artifact xml into a jar (Default is "true") |
|
format
|
A URL to another repository from which to copy the repository name and other properties. |
|
|
Specifying Installable Units
|
Some p2 tasks allow specifying installable units to work with. This is done with nested <iu> elements which support the following attributes:
|
id
|
The id of the IU to match. |
|
version
|
The version of the IU to match. If not specified, the highest versioned IU is returned. (requires id to be set) |
|
query
|
Matches all IUs satisfying the query. Currently only "property" queries are supported.
The format of the query attribute is intended to be "xpath-like". Eg:
<iu query="property[@name='org.eclipse.equinox.p2.type.category']" />
<iu query="property[@name='my.property.name' @value='specialValue']" />
|
|
Ant Tasks
|
p2.mirror
|
|
This task mirrors artifacts and metadata from the given source repositories to the destination.
This task will traverse the source repository and recursively include all IUs that match the requirements of IUs being mirrored (this is called slicing the repository).
|
|
This task supports the following attributes and elements:
|
source
|
Source repositories, as outlined
above
|
|
desination
|
Destination repositories, as outlined
above
|
|
<iu>
|
Nested IU elements, as outlined
above.
The installable units to mirror. If none are specified, all IUs contained in the source repositories are mirrored. |
|
log
|
A file to use for logging the results. |
|
ignoreErrors
|
Whether or not to ignore errors. (Default is false) |
|
raw
|
Copy the exact artifact descriptors from source into the destination instead of
initializing new artifact descriptors with properties from the source descriptors. (Default is true) |
|
verbose
|
Turn on verbose logging. |
|
validate
|
Validate that all all source descriptors are present in the
destination after mirroring is complete. (Default is false) |
|
<comparator>
|
A nested comparator element for comparing against a baseline repository.
If IUs from the source repository already exist in the baseline, then the artifacts will be mirrored from
the baseline instead of the source. This element supports the following attributes:
|
<baseline>
|
A nested element specifying the baseline repository.
See
destination repositories
above. |
|
comparator
|
Id of a comparator to use if the baseline artifacts should be compared
against the source artifacts. These are extensions to the org.eclipse.equinox.p2.artifact.repository.artifactComparators extension point.
Comparators provided by p2 are:
-
org.eclipse.equinox.p2.repository.tools.jar.comparator: Compare jars.
Class files are disassembled and compared for equivalence, properties and manifest files are compared as such, all other files are compared byte-for-byte.
-
org.eclipse.equinox.artifact.md5.comparator: Compare the MD5 sums as recorded in the artifact repositories.
|
|
comparatorLog
|
A log file for the results of the comparison. |
|
|
<slicingOptions>
|
A nested element for specifying how to slice the
repositories to bring in additional IUs. This element supports the following attributes:
|
followStrict
|
Set to true if only strict dependencies should be followed.
A strict dependency is defined by a version range only including one version (e.g. [1.0.0.v2009, 1.0.0.v2009]). (Default is false) |
|
includeOptional
|
Whether or not to follow optional requirements. (Default is true). |
|
includeNonGreedy
|
Whether or not to follow non-greedy requirements. (Default is true). |
|
includeFeatures
|
Whether or not to include features. (Default is true). |
|
platformFilter
|
An "os,ws,arch" triplet to set as the platform against which IU LDAP filters will be matched.
IUs not matching the filter will not be mirrored. |
|
filter
|
Set additional filter properties. Format is a comma separated list of "key=value" pairs. |
|
followOnlyFilteredRequirements
|
Invert the filters, include only the IUs that don't match. |
|
|
Examples:
Creating a delta pack repository based on the contents of the platform, rcp, jdt and equinox.executable features:
<p2.mirror source="file://${buildRepo}">
<destination kind="metadata" location="file://${deltaTemp}" name="RCP Delta Pack Repo" />
<destination kind="artifact" location="file://${deltaTemp}" name="RCP Delta Pack Repo" />
<iu id="org.eclipse.platform.feature.group" version="" />
<iu id="org.eclipse.rcp.feature.group" version="" />
<iu id="org.eclipse.jdt.feature.group" version="" />
<iu id="org.eclipse.equinox.executable" version="" />
<slicingOptions includeOptional="false" includeNonGreedy="false" followStrict="true" followOnlyFilteredRequirements="true" />
</p2.mirror>
Mirror the org.eclipse.equinox.p2.user.ui feature and other required bundles locally (perhaps in preparation for a build).
<p2.mirror source="https://download.eclipse.org/releases/galileo" destination="${p2Repo}">
<slicingOptions followStrict="true" />
<iu id="org.eclipse.equinox.p2.user.ui.feature.group" />
<iu id="org.eclipse.ecf"/>
<iu id="org.eclipse.ecf.filetransfer"/>
<iu id="org.eclipse.ecf.identity"/>
<iu id="org.eclipse.ecf.provider.filetransfer"/>
<iu id="org.eclipse.ecf.provider.filetransfer.httpclient"/>
<iu id="org.eclipse.ecf.provider.filetransfer.httpclient.ssl" />
<iu id="org.eclipse.ecf.provider.filetransfer.ssl"/>
<iu id="org.eclipse.ecf.ssl" />
<iu id="org.apache.commons.codec"/>
<iu id="org.apache.commons.httpclient"/>
<iu id="org.apache.ant"/>
<iu id="org.eclipse.core.runtime.compatibility.registry"/>
</p2.mirror>
Mirror the results of a build into a public location, and compare against the existing update site to ensure that artifacts
haven't changed if their versions haven't been updated.
<p2.mirror source="file:${buildRepo}" ignoreErrors="true" log="${buildlogs}/mirrorlog.txt">
<destination compressed="true" name="${p2.repo.name}" location="file:${updateRepo}" append="true" />
<comparator comparator="org.eclipse.equinox.p2.repository.tools.jar.comparator" comparatorLog="${buildlogs}/comparatorlog.txt">
<repository location="file:${updateSite}" />
</comparator>
</p2.mirror>
|
p2.repo2runnable
|
|
Transform IUs into their installed form and add them to the destination repository. This allows compiling against folder
shaped bundles that contain nested jars. This task is the main mechanism by which headless PDE/Builds can reuse metadata.
|
|
This task supports the following attributes and elements:
|
source
|
Source repositories, as outlined
above
|
|
desination
|
Destination repositories, as outlined
above
|
|
<iu>
|
Nested IU elements, as outlined
above.
The installable units to transform. If none are specified, all IUs contained in the source repositories are transformed. |
|
|
p2.process.artifacts
|
|
Process a local, file-based artifact repository. This task will (optionally) sign and pack artifacts,
as well as update the MD5 sums in the repository to match the actual artifacts on disk (since signing/conditioning will change the MD5 sums).
This task will use the jarProcessor, which in turn uses ant's SignJar task which requires the jarsigner command line tool.
|
|
This task supports the following attributes and elements:
|
repositoryPath
|
A URL to an artifact repository to process. This must be a local, file-based repository. |
|
pack
|
Whether or not to create pack.gz artifacts. (Default is false) |
|
normalize
|
Whether or not to do pack200(pack + unpack) conditioning on the artifacts.
(Default is false, however sign + pack will imply a normalize.) |
|
repositoryPath
|
A URL to an artifact repository to process. This must be a local, file-based repository. |
|
<sign>
|
A nested element to enable signing. This element supports the following attributes:
|
alias
|
The alias to sign with |
|
keystore
|
The location of the keystore. |
|
keypass
|
Password for the private key (if different). |
|
storepass
|
Password for the key store. |
|
unsign
|
Whether or not to strip any existing signatures before signing. (Default is false) |
|
|
<feature>
|
Nested elements specifying features IUs to process
(see
above, the query attribute is not supported here).
If no features or plug-ins are specified, the entire repository is processed. |
|
<plugin>
|
Nested elements specifying plugins IUs to process
(see
above, the query attribute is not supported here).
If no features or plug-ins are specified, the entire repository is processed. |
|
|
p2.composite.repository
|
|
Create a composite repository
|
|
This task supports the following attributes and elements:
|
failOnExists
|
Whether we should fail if the repository already exists. (Default is false) |
|
validate
|
A comparator-id. Child repositories claiming to contain the same artifact are
compared using the given comparator. These are extensions to the org.eclipse.equinox.p2.artifact.repository.artifactComparators
extension point. Comparators provided by p2 are:
-
org.eclipse.equinox.p2.repository.tools.jar.comparator: Compare jars. Class files are disassembled and
compared for equivalence, properties and manifest files are compared as such, all other files are compared byte-for-byte.
-
org.eclipse.equinox.artifact.md5.comparator: Compare the MD5 sums as recorded in the artifact repositories.
|
|
<add>
|
A nested element containing a list of repositories to add to the composite.
See
source repositories above. |
