Hi P2 experts, We are preparing initial release of EclEmma < https://projects.eclipse.org/projects/technology.eclemma> under Eclipse Foundation umbrella. And we would like to provide for our users smooth transition from its ancestor <https://github.com/jacoco/eclemma>.
So as was advised by our mentor Mickael Istria - based on < https://github.com/eclipse/m2e.wtp/blob/master/org.eclipse.m2e.wtp.feature/p2.inf> I've tried to create p2.inf Here is its content with comments describing my assumptions: ### # can update any "com.mountainminds.eclemma.feature" and previous versions of "org.eclipse.eclemma.feature" update.matchExp = providedCapabilities.exists(pc | pc.namespace \=\= 'org.eclipse.equinox.p2.iu' && (pc.name \=\= 'com.mountainminds.eclemma.feature.feature.group' || pc.name \=\= 'org .eclipse.eclemma.feature.feature.group' && pc.version < '$version$')) # requires additional IU described below requires.0.namespace=osgi.bundle requires.0.name=com.mountainminds.eclemma requires.0.range=[$version$, $version$] units.1.id=com.mountainminds.eclemma units.1.version=$version$ units.1.singleton=true units.1.provides.0.namespace=osgi.bundle units.1.provides.0.name=com.mountainminds.eclemma units.1.provides.0.version=$version$ # to not overwrite the main artifact, the additional IU should have classifier (https://bugs.eclipse.org/bugs/show_bug.cgi?id=430728) units.1.properties.1.name=maven-classifier units.1.properties.1.value=p2inf # TODO explain units.1.properties.0.name=org.eclipse.equinox.p2.name units.1.properties.0.value=This version cannot be installed on top of the already installed EclEmma plugin. Uninstall the previous version and try the install again. ### And below is a description of performed testing with undesirable outcome. Using: fresh installation of Eclipse IDE for Java Developers (Version: Neon.1a Release (4.6.1) Build id: 20161007-1200) Given: old 2.3.3.201602231923 installed from <http://update.eclemma.org/> When: installing new one from local build directory Then: correctly upgraded to 2.3.4.201610291259 When: new build is available and checking for update Then: correctly upgraded to more newer 2.3.4.201610291310 When: installing old one from <http://update.eclemma.org/> Expected: failure Actual: both (2.3.3.201602231923 and 2.3.4.201610291310) are installed Any help/ideas are more than welcome. Regards, Evgeny
