Hi all, we've just noticed a weird behavior of p2 during installation.
Here are the steps to reproduce: - Install the bare 4.5-M4 SDK [1]. Note that it does not contain any bundles from Eclipse Code Recommenders, Aether, or m2e. - Next, install the latest version of "Code Recommenders for Java Developers" from [2] This installs all the bundles from Code Recommenders, some bundles from Aether (which are made available through [2]) and(!) the bundle org.eclipse.m2e.maven.runtime from [3], the update site pre-configured by 4.5 M4. And herein lies the problem: > osgi> ss recommenders > "Framework is launched." > > > id State Bundle > 263 INSTALLED org.eclipse.recommenders.apidocs_2.1.12.v20141202-0751 > 264 INSTALLED org.eclipse.recommenders.apidocs.rcp_2.1.12.v20141202-0751 > 265 INSTALLED org.eclipse.recommenders.calls_2.1.12.v20141202-0751 > 266 INSTALLED org.eclipse.recommenders.calls.rcp_2.1.12.v20141202-0751 > 267 STARTING org.eclipse.recommenders.chain.rcp_2.1.12.v20141202-0751 > 268 STARTING > org.eclipse.recommenders.completion.rcp_2.1.12.v20141202-0751 > 269 STARTING org.eclipse.recommenders.injection_2.1.12.v20141202-0751 > 270 RESOLVED org.eclipse.recommenders.jayes_2.1.12.v20141202-0751 > 271 RESOLVED org.eclipse.recommenders.jayes.io_2.1.12.v20141202-0751 > 272 RESOLVED org.eclipse.recommenders.jdt_2.1.12.v20141217-0920 > 273 INSTALLED org.eclipse.recommenders.models_2.1.12.v20141211-1032 > 274 INSTALLED org.eclipse.recommenders.models.rcp_2.1.12.v20141203-0852 > 275 RESOLVED org.eclipse.recommenders.net_2.1.12.v20141202-0751 > 276 INSTALLED org.eclipse.recommenders.overrides_2.1.12.v20141202-0751 > 277 INSTALLED org.eclipse.recommenders.overrides.rcp_2.1.12.v20141202-0751 > 278 STARTING org.eclipse.recommenders.rcp_2.1.12.v20141202-0751 > 279 RESOLVED org.eclipse.recommenders.subwords.rcp_2.1.12.v20141202-0751 > 280 RESOLVED org.eclipse.recommenders.utils_2.1.12.v20141211-1252 Code Recommenders is totally unusable. The root cause is that it cannot resolve some package imports of org.eclipse.aether, even though the org.eclipse.aether.api bundle is present on the Code Recommenders update site [2]. > osgi> diag 273 > org.eclipse.recommenders.models [273] > Unresolved requirement: Import-Package: > org.apache.maven.repository.internal; version="[3.1.0,3.2.0)" > -> Export-Package: org.apache.maven.repository.internal; > bundle-symbolic-name="org.eclipse.aether.maven"; > bundle-version="3.1.0.v20140706-2237"; version="3.1.0"; > uses:="com.google.inject,javax.inject,org.eclipse.aether,org.eclipse.aether.artifact,org.eclipse.aether.deployment,org.eclipse.aether.impl,org.eclipse.aether.installation,org.eclipse.aether.repository,org.eclipse.aether.resolution,org.eclipse.aether.spi.locator,org.eclipse.aether.spi.log" > org.eclipse.aether.maven [255] > Unresolved requirement: Import-Package: org.eclipse.aether; > version="[0.9.1,1.1.0)" This is due to the fact that p2 has installed the bundle org.eclipse.m2e.maven.runtime instead as a provider of the package org.eclipse.aether: > osgi> p org.eclipse.aether > osgi.wiring.package; bundle-symbolic-name="org.eclipse.m2e.maven.runtime"; > bundle-version:Version="1.6.0.20141217-0916"; provider="m2e"; > version:Version="1.0.0.v20140518"; osgi.wiring.package="org.eclipse.aether"; > mandatory:="provider"<org.eclipse.m2e.maven.runtime_1.6.0.20141217-0916 [261]> But this bundle is not a valid substitute for the org.eclipse.aether.api bundle, due to the mandatory provider attribute of "m2e". Is this a bug in p2? IMHO, p2 should be able to detect that org.eclipse.m2e.maven.runtime does not provide the necessary package for the bundle org.eclipse.aether.maven to import, as the latter's Import-Package does not use provider="m2e". FWIW, for the history of the provider="m2e" attribute added [4] precisely to avoid these kind of wiring problems, see Bug 403243 [5]. Any insights as to why p2 behaves the way it does are greatly appreciated.
