Generates a compatibility matrix for plugins against Jenkins core.
See https://wiki.jenkins-ci.org/display/JENKINS/Plugin+Compatibility+Tester for background.
It is recommended to run PCT in the prepared Docker image. You can find it here.
This command will clone of a repository and run PCT against the latest Jenkins Core:
docker run --rm -v maven-repo:/root/.m2 -v $(pwd)/out:/pct/out -e ARTIFACT_ID=ssh-slaves -e VERSION=ssh-slaves-1.24 jenkins/pct
This command will run PCT for the latest plugin version against the specified Jenkins WAR. PCT supports running against SNAPSHOT builds, but PCT will have to install local Maven artifacts in such case.
docker run --rm -v maven-repo:/root/.m2 -v $(pwd)/out:/pct/out -v my/jenkins.war:/pct/jenkins.war:ro -e ARTIFACT_ID=ssh-slaves jenkins/pct
This command will run PCT against custom versions of Jenkins and the plugin specified by volumes.
docker run --rm -v maven-repo:/root/.m2 -v $(pwd)/out:/pct/out -v my/jenkins.war:/pct/jenkins.war:ro -v my/plugin:/pct/plugin-src:ro jenkins/pct
The command below will run PCT for a branch in a custom repository.
docker run --rm -v maven-repo:/root/.m2 -v $(pwd)/out:/pct/out -e CHECKOUT_SRC=https://github.com/oleg-nenashev/job-restrictions-plugin.git -e VERSION=JENKINS-26374 jenkins/pct
Environment variables:
ARTIFACT_ID
- ID of the artifact to be tested. The image will be able to determine this ID automatically ifCHECKOUT_SRC
or/pct/plugin-src
are defined.VERSION
- tag/commit/branch to be checked out and tested.master
by defaultCHECKOUT_SRC
- Custom Git clone source (e.g.https://github.com/oleg-nenashev/job-restrictions-plugin.git
).https://github.com/jenkinsci/${ARTIFACT_ID}-plugin.git
by defaultJAVA_OPTS
- Java options to be passed to the PCT CLIDEBUG
- Boolean flag, which enables the Remote Debug mode (port == 5000)M2_SETTINGS_FILE
- If set indicates the path of the custom maven settings file to use (see volumes below)INSTALL_BUNDLED_SNAPSHOTS
- Install JAR and plugin snapshots to local repository.true
by default. WAR snapshots will be always installed.
Volumes:
/pct/plugin-src
- Plugin sources to be used for the PCT run. Sources will be checked out if not specified/pct/jenkins.war
- Jenkins WAR file to be used for the PCT run/pct/m2-settings.xml
- Custom Maven Settings (optional) ifM2_SETTINGS_FILE
environment variable existsrun-pct
will ignore this location and use the one specified in the variable/pct/out
- Output directory for PCT. All reports will be stored there/pct/tmp
- Temporary directory. Can be exposed to analyze run failures/root/.m2
- Maven repository. It can be used to pass settings.xml or to cache artifacts
PCT offers the CLI interface which can be used to run PCT locally.
- Download
PCT
and executemvn clean install
- Download plugin sources to a
PLUGIN_SRC
directory. - Checkout the plugin repo to a tag/commit/branch you want to test
- Run
mvn clean install -DskipTests
to initialize artifacts - Go to
PCT
folder and run the CLI (make sure to modify paths according to your system). Example:
java -jar plugins-compat-tester-cli/target/plugins-compat-tester-cli-${PCT_VERSION}.jar \
-reportFile $(pwd)/out/report.xml \
-workDirectory $(pwd)/tmp/work \
-includePlugins ${PLUGIN_ARTIFACT_ID} \
-war jenkins.war -localCheckoutDir ${PLUGIN_SRC} \
-skipTestCache true \
-mvn ${PATH_TO_MAVEN}
You can run the CLI with the -help
argument to get a full list of supported options.
❗ For the moment testing more than one plugin at once requires plugins to be released, so for testing SNAPSHOTS you need to execute the last step for every plugin you want to test*
Plugin compat tester supports running Test Suites with a Java version different from the one being used to run PCT and build the plugins. For example, such mode can be used to run tests with JDK11 while the plugin build flow is not adapted to it.
Two options can be passed to PCT CLI for such purpose:
testJDKHome
- A path to JDK HOME to be used for running tests in pluginstestJavaArgs
- Java test arguments to be used for test runs. For JDK 11 this option may be used to pass modules and the classpath
You can run the example by running the following command:
make demo-jdk11 -e TEST_JDK_HOME=${YOUR_JDK11_HOME}
Full list of options for JDK11 can be found here.
If you need to debug a dockerized PCT instance,
use the -e DEBUG=true -p 5005:5005
flags and then attach to the container using Remote Debugger in your IDE.
docker run --rm -v maven-repo:/root/.m2 -v $(pwd)/out:/pct/out -e ARTIFACT_ID=job-restrictions -e DEBUG=true -p 5005:5005 -i jenkins/pct
To do (refile in plugin-compat-tester
in JIRA!):
InternalMavenRunner
currently still seems to runinstall
goal which is very undesirable on release tags- should run
surefire-report:report
goal instead (orsurefire-report:report-only
after) and display link to HTML results from index page - Export everything to GAE, dropping the data storing in XML files (which pollutes the filesystem and can be easily delete if we are careless) and processing with XSL. (migration already started to GAE datastorage, but not completely finished, especially on build logs). (jglick: this is undesirable, need to be able to review local results without uploading them)
- Improve GAE app to allow plugin maintainers to subscribe to notifications on plugin compatibility tests for their plugins against new jenkins versions released.
- Remove possibility, on GAE app, to select both "every plugins" and "every cores" results... because it generates too much results and crash GAE datastore
- most plugin tests fail to build using internal Maven;
PlexusWagonProvider.lookup
with aroleHint=https
fails for no clear reason, and some missingSNAPSHOT
s cause a build failure related to https://github.com/stapler/stapler-adjunct-codemirror/commit/da995b03a1f165fef7c9d34eadb15797f58399cd - testing a module not at the root of its Git repo fails (
findbugs
succeeds but tests against old Jenkins core) - testing
analysis-core
fails because it usesorg.jvnet.hudson.plugins:analysis-pom
as a parent - when testing a plugin depending on other plugins, bump up the dependency to the latest released version…or even build the dependency from
master
