When I tried to update m2e to the latest 0.13 nightly version I get the following error from Eclipse: Cannot complete the install because of a conflicting dependency. Software being installed: m2e - Maven Integration for Eclipse (Incubation) 0.13.0.201104090003 (org.eclipse.m2e.feature.feature.group 0.13.0.201104090003) Software currently installed: Maven SCM Handler for Subversive 0.13.0.201102141719 (org.sonatype.m2e.subversive.feature.feature.group 0.13.0.201102141719) Only one of the following can be installed at once: Maven Integration for Eclipse 0.13.0.201104011605 (org.eclipse.m2e.core.ui 0.13.0.201104011605) Maven Integration for Eclipse 0.14.0.201103241508 (org.eclipse.m2e.core.ui 0.14.0.201103241508) Cannot satisfy dependency: From: m2e - Maven Integration for Eclipse (Incubation) 0.13.0.201104090003 (org.eclipse.m2e.feature.feature.group 0.13.0.201104090003) To: org.eclipse.m2e.core.ui [0.14.0.201103241508] Cannot satisfy dependency: From: SCM Maven Integration for Eclipse 0.13.0.201104011605 (org.eclipse.m2e.scm 0.13.0.201104011605) To: bundle org.eclipse.m2e.core.ui [0.13.0,0.14.0) Cannot satisfy dependency: From: Maven SCM Handler for Subversive 0.13.0.201102141719 (org.sonatype.m2e.subversive 0.13.0.201102141719) To: bundle org.eclipse.m2e.scm [0.13.0,0.14.0) Cannot satisfy dependency: From: Maven SCM Handler for Subversive 0.13.0.201102141719 (org.sonatype.m2e.subversive.feature.feature.group 0.13.0.201102141719) To: org.sonatype.m2e.subversive [0.13.0.201102141719] Seems that the feature still has an invalid dependency to the 0.14 version.
I don't see anything wrong with the dependencies, if you have m2e 0.14 installed try removing it first.
After uninstalling all m2e plugins reinstallation went well, but still the latest nightly build from the eclipse update site contains a 0.14 version from Maven Integration for Eclipse - slf4j over logback logging (Optional) (org.eclipse.m2e.logback.feature.feature.group, 0.14.0.201103241508). Also the m2e marketplace does not work. The error log says: org.eclipse.core.runtime.CoreException: IO failure: cannot load discovery directory at org.eclipse.equinox.internal.p2.discovery.compatibility.RemoteBundleDiscoveryStrategy.performDiscovery(RemoteBundleDiscoveryStrategy.java:96) at org.eclipse.equinox.internal.p2.discovery.Catalog.performDiscovery(Catalog.java:85) at org.eclipse.m2e.internal.discovery.wizards.MavenCatalogViewer$2.run(MavenCatalogViewer.java:164) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:121) Caused by: java.io.FileNotFoundException: http://download.eclipse.org/technology/m2e/discovery/0.14.0/directory.xml at org.eclipse.equinox.internal.p2.repository.RepositoryStatusHelper.checkFileNotFound(RepositoryStatusHelper.java:295) at org.eclipse.equinox.internal.p2.repository.FileInfoReader.checkException(FileInfoReader.java:218) at org.eclipse.equinox.internal.p2.repository.FileInfoReader.getRemoteFiles(FileInfoReader.java:110) at org.eclipse.equinox.internal.p2.repository.FileInfoReader.getRemoteFile(FileInfoReader.java:123) at org.eclipse.equinox.internal.p2.repository.FileInfoReader.getLastModified(FileInfoReader.java:128) at org.eclipse.equinox.internal.p2.repository.RepositoryTransport.getLastModified(RepositoryTransport.java:224) at org.eclipse.equinox.internal.p2.discovery.compatibility.util.CacheManager.createCache(CacheManager.java:101) at org.eclipse.equinox.internal.p2.discovery.compatibility.util.TransportUtil.readResource(TransportUtil.java:101) at org.eclipse.equinox.internal.p2.discovery.compatibility.RemoteBundleDiscoveryStrategy.performDiscovery(RemoteBundleDiscoveryStrategy.java:81) ... 3 more There seems to be the wrong version 0.14 still somewhere in the code.
Looks like something odd has happened with the build, looking at the repositories from the last couple days we seem to have files from when we mistakenly bumped the version to 0.14 for some reason. I'll take a look at this, in the mean time the most recent good build is available: https://repository.sonatype.org//content/sites/forge-sites/m2e/0.13.0/N/0.13.0.201104081709/
The problem on the build machine was fixed.
