Dear all, I came across some problems regarding the proxy configuration used by m2e in Eclipse. When creating a new maven project from the scratch the build fails and I receive from eclipse the error message:
Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6 Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6 Neither a successful maven project build without previous archetype selection nor any with archetype selection is possible. In Eclipse's New Maven project wizard for my configured remote catalog no archetypes are listed. I configured the remote repository in Eclipse>Preferences>Maven>Archetypes which is https://repo1.maven.org/maven2/archetype-catalog.xml (also tried different). In this dialog when pressing the verify button the error message "Remote catalog is empty" is returned. In order to fix the problem, I goggled a little bit around and verified that my proxy settings in settings.xml are the same as in the eclipse>preferences>network connections (accessing e.g. Eclipse Marketplace via the indicated proxy works fine). Furthermore, I also deleted the existing local user repository saved under C:\Users\<username>\.m2\repository in order to force an update of the project with accurate dependencies. I am running on - Eclipse Java EE IDE for Web Developers, Version: Neon.2 Release (4.6.2), Build id: 20161208-0600 - Maven Integration for Eclipse, Version 1.7.0-20160603-1933 (the embedded one) - http proxy which user authorisation My guess is that m2e is not using the proxy settings indicated in the settings.xml file. Do you have any ideas how to fix this problem or should I report a bug? In detail, the java stack trace is: org.apache.maven.plugin.PluginResolutionException: Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6 at org.apache.maven.plugin.internal.DefaultPluginDependenciesResolver.resolve(DefaultPluginDependenciesResolver.java:117) at org.eclipse.m2e.core.internal.project.registry.EclipsePluginDependenciesResolver.resolve(EclipsePluginDependenciesResolver.java:47) at org.apache.maven.plugin.internal.DefaultMavenPluginManager.getPluginDescriptor(DefaultMavenPluginManager.java:179) at org.apache.maven.plugin.internal.DefaultMavenPluginManager.getMojoDescriptor(DefaultMavenPluginManager.java:284) at org.apache.maven.plugin.DefaultBuildPluginManager.getMojoDescriptor(DefaultBuildPluginManager.java:241) at org.apache.maven.lifecycle.internal.DefaultLifecycleExecutionPlanCalculator.setupMojoExecution(DefaultLifecycleExecutionPlanCalculator.java:169) at org.eclipse.m2e.core.internal.embedder.MavenImpl.setupMojoExecution(MavenImpl.java:408) at org.eclipse.m2e.core.internal.embedder.MavenImpl$2.call(MavenImpl.java:420) at org.eclipse.m2e.core.internal.embedder.MavenImpl$2.call(MavenImpl.java:1) at org.eclipse.m2e.core.internal.embedder.MavenExecutionContext.executeBare(MavenExecutionContext.java:176) at org.eclipse.m2e.core.internal.embedder.MavenExecutionContext.execute(MavenExecutionContext.java:112) at org.eclipse.m2e.core.internal.embedder.MavenImpl.setupMojoExecution(MavenImpl.java:418) at org.eclipse.m2e.core.internal.project.registry.ProjectRegistryManager.setupMojoExecution(ProjectRegistryManager.java:961) at org.eclipse.m2e.core.internal.project.registry.MavenProjectFacade.getMojoExecution(MavenProjectFacade.java:408) at org.eclipse.m2e.core.project.configurator.AbstractCustomizableLifecycleMapping.getBuildParticipants(AbstractCustomizableLifecycleMapping.java:66) at org.eclipse.m2e.core.internal.builder.MavenBuilder$BuildMethod$1$1.call(MavenBuilder.java:113) at org.eclipse.m2e.core.internal.embedder.MavenExecutionContext.executeBare(MavenExecutionContext.java:176) at org.eclipse.m2e.core.internal.embedder.MavenExecutionContext.execute(MavenExecutionContext.java:112) at org.eclipse.m2e.core.internal.builder.MavenBuilder$BuildMethod$1.call(MavenBuilder.java:105) at org.eclipse.m2e.core.internal.embedder.MavenExecutionContext.executeBare(MavenExecutionContext.java:176) at org.eclipse.m2e.core.internal.embedder.MavenExecutionContext.execute(MavenExecutionContext.java:151) at org.eclipse.m2e.core.internal.embedder.MavenExecutionContext.execute(MavenExecutionContext.java:99) at org.eclipse.m2e.core.internal.builder.MavenBuilder$BuildMethod.execute(MavenBuilder.java:86) at org.eclipse.m2e.core.internal.builder.MavenBuilder.build(MavenBuilder.java:200) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:735) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:206) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:246) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:301) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:304) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:360) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:383) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:144) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:235) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) Caused by: org.eclipse.aether.resolution.ArtifactDescriptorException: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6 at org.apache.maven.repository.internal.DefaultArtifactDescriptorReader.loadPom(DefaultArtifactDescriptorReader.java:282) at org.apache.maven.repository.internal.DefaultArtifactDescriptorReader.readArtifactDescriptor(DefaultArtifactDescriptorReader.java:198) at org.eclipse.aether.internal.impl.DefaultRepositorySystem.readArtifactDescriptor(DefaultRepositorySystem.java:287) at org.apache.maven.plugin.internal.DefaultPluginDependenciesResolver.resolve(DefaultPluginDependenciesResolver.java:103) ... 35 more Caused by: org.eclipse.aether.resolution.ArtifactResolutionException: Failure to transfer org.apache.maven.plugins:maven-resources-plugin:pom:2.6 from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced.
