SetRequiredBundleVersionRanges
SetRequiredBundleVersionRanges is an Ant task used to automatically set RequiredBundle version range values in MANIFEST.MF files during EMF builds, rather than having to set them manually and update them manually.
Setup
Here's how it works:
This plugin is used as a jarred plugin during the EMF build, like this:
- 1. Eclipse Build is started from build.sh.
scriptsDir="/home/www-data/emf-build/scripts"; echo "Copy $scriptsDir/org.eclipse.emf.build.ant*.jar to $relengBaseBuilderDir/plugins/"; for f in `find $scriptsDir -name "org.eclipse.emf.build.ant*.jar"`; do cp $f $relengBaseBuilderDir/plugins/; done echo Invoking Eclipse build command="$vm -cp $relengBaseBuilderDir/startup.jar org.eclipse.core.launcher.Main" command=$command" -application org.eclipse.ant.core.antRunner" command=$command" -f $antScript $target" # for testing, add -verbose before -f to increase log verbosity (and also size!) #command=$command" $bootclasspath" # removed: this is now specified in the ant task command=$command" -DmapVersionTag=$mapVersionTag" command=$command" -DbuildType=$buildType" command=$command" $buildID" command=$command" $buildTimestamp" command=$command" $buildDir" command=$command" $buildAlias" command=$command" $downloadsDir" command=$command" $rsyncPWFile $ftpUser $ftpPassword" $baseDir/scripts/executeCommand.sh "$command"
- 2. PDE build looks in all available customTargets.xml files.
<emf.build.SetRequiredBundleVersionRanges verbose="true"> <manifestSet dir="${eclipse.plugins}"> <include name="org.eclipse.emf*/META-INF/MANIFEST.MF" /> <include name="org.eclipse.xsd*/META-INF/MANIFEST.MF" /> <exclude name="*-feature/**" /> </manifestSet> <dependencySet dir="${eclipse.plugins}"> <include name="*.jar" /> <include name="*/META-INF/MANIFEST.MF" /> <exclude name="org.eclipse.emf*/**" /> <exclude name="org.eclipse.xsd*/**" /> </dependencySet> <versionRangeRule requiredBundleRegex="org\.eclipse\.(emf|xsd)" /> <versionRangeRule lowerVersion="{current}.{current}.0" /> </emf.build.SetRequiredBundleVersionRanges>
- For more on how to use the <versionRangeRule> and other subtasks, see the javadoc in the class source for emf.build.SetRequiredBundleVersionRanges (eg., open in Eclipse). You can also view it as loosely formatted HTML.
- 3. emf.build.SetRequiredBundleVersionRanges task, as defined in the plugin.xml file, is then run to manipulate MANIFEST.MF files.
Output
For a file such as org.eclipse.emf.ecore/META-INF/MANIFEST.MF:
Manifest-Version: 1.0 Bundle-ManifestVersion: 2 Bundle-Name: %pluginName Bundle-SymbolicName: org.eclipse.emf.ecore; singleton:=true Bundle-Version: 2.2.0.qualifier Bundle-ClassPath: ecore.jar Bundle-Activator: org.eclipse.emf.ecore.plugin.EcorePlugin$Implementation Bundle-Vendor: %providerName Bundle-Localization: plugin Export-Package: org.eclipse.emf.ecore, org.eclipse.emf.ecore.impl, org.eclipse.emf.ecore.plugin, org.eclipse.emf.ecore.resource, org.eclipse.emf.ecore.resource.impl, org.eclipse.emf.ecore.util, org.eclipse.emf.ecore.xml.namespace, org.eclipse.emf.ecore.xml.namespace.impl, org.eclipse.emf.ecore.xml.namespace.util, org.eclipse.emf.ecore.xml.type, org.eclipse.emf.ecore.xml.type.impl, org.eclipse.emf.ecore.xml.type.internal, org.eclipse.emf.ecore.xml.type.util Require-Bundle: org.eclipse.core.runtime, org.eclipse.emf.common;visibility:=reexport, org.eclipse.core.resources;resolution:=optional Eclipse-LazyStart: true
The resulting MANIFEST.MF file will look like this:
Manifest-Version: 1.0 Bundle-Name: %pluginName Bundle-ClassPath: . Bundle-Activator: org.eclipse.emf.ecore.plugin.EcorePlugin$Implementat ion Bundle-Vendor: %providerName Bundle-ManifestVersion: 2 Bundle-Localization: plugin Bundle-SymbolicName: org.eclipse.emf.ecore; singleton:=true Require-Bundle: org.eclipse.core.runtime;bundle-version="[3.2.0,4.0.0) ",org.eclipse.emf.common;visibility:=reexport;bundle-version="[2.2.0, 3.0.0)",org.eclipse.core.resources;resolution:=optional;bundle-versio n="[3.2.0,4.0.0)" Export-Package: org.eclipse.emf.ecore,org.eclipse.emf.ecore.impl,org.e clipse.emf.ecore.plugin,org.eclipse.emf.ecore.resource,org.eclipse.em f.ecore.resource.impl,org.eclipse.emf.ecore.util,org.eclipse.emf.ecor e.xml.namespace,org.eclipse.emf.ecore.xml.namespace.impl,org.eclipse. emf.ecore.xml.namespace.util,org.eclipse.emf.ecore.xml.type,org.eclip se.emf.ecore.xml.type.impl,org.eclipse.emf.ecore.xml.type.internal,or g.eclipse.emf.ecore.xml.type.util Bundle-Version: 2.2.0.v200606271057 Eclipse-LazyStart: true
This tool works with both jarred and unjarred plugins. EMF's doc plugin is currently unjarred for performance reasons, and contains this MANIFEST.MF file:
Manifest-Version: 1.0 Bundle-ManifestVersion: 2 Bundle-Name: %pluginName Bundle-SymbolicName: org.eclipse.emf.doc; singleton:=true Bundle-Version: 2.2.0.qualifier Bundle-Vendor: %providerName Bundle-Localization: plugin Require-Bundle: org.eclipse.help Eclipse-LazyStart: true
Manifest-Version: 1.0 Bundle-Name: %pluginName Bundle-Vendor: %providerName Bundle-ManifestVersion: 2 Bundle-Localization: plugin Bundle-SymbolicName: org.eclipse.emf.doc; singleton:=true Require-Bundle: org.eclipse.help;bundle-version="[3.2.0,4.0.0)" Bundle-Version: 2.2.0.v200606271057 Eclipse-LazyStart: true
Note:
- The hard line wrapping is added when PDE edits and saves these files.
- The reason that
Bundle-Version: 2.2.0.qualifier
becomesBundle-Version: 2.2.0.v200606271057
is due to another PDE tool, and is unrelated to this task.
