My PR adding the creation of a karaf feature repository file and attaching the feature repository to the JDBC driver, has problems in the JDBC driver team's RH EL7 build: https://github.com/pgjdbc/pgjdbc/pull/1554#issuecomment-535722657 https://github.com/pgjdbc/pgjdbc/pull/1554#issuecomment-536174617
Does anyone see what the problem is? (I have googled NoSuchElementException and karaf but haven't found anything obvious). Here are version numbers of maven and java (kind of old maven, but an as recent as possible java 8) from the build machine and a stack trace from the maven build failure: mvn --version Apache Maven 3.0.5 (Red Hat 3.0.5-17) Maven home: /usr/share/maven Java version: 1.8.0_222, vendor: Oracle Corporation Java home: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.222.b10-1.el7_7.x86_64/jre Default locale: en_CA, platform encoding: UTF-8 OS name: "linux", version: "3.10.0-693.21.1.el7.x86_64", arch: "amd64", family: "unix" org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.karaf.tooling:karaf-maven-plugin:4.2.5:features-generate-descriptor (generate-features-file) on project postgresql: Unable to create features.xml file: org.apache.maven.plugin.MojoExecutionException: java.util.NoSuchElementException role: org.eclipse.aether.RepositorySystem roleHint: at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:217) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:153) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:145) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:84) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:59) at org.apache.maven.lifecycle.internal.LifecycleStarter.singleThreadedBuild(LifecycleStarter.java:183) at org.apache.maven.lifecycle.internal.LifecycleStarter.execute(LifecycleStarter.java:161) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:320) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:156) at org.apache.maven.cli.MavenCli.execute(MavenCli.java:537) at org.apache.maven.cli.MavenCli.doMain(MavenCli.java:196) at org.apache.maven.cli.MavenCli.main(MavenCli.java:141) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.codehaus.plexus.classworlds.launcher.Launcher.launchEnhanced(Launcher.java:290) at org.codehaus.plexus.classworlds.launcher.Launcher.launch(Launcher.java:230) at org.codehaus.plexus.classworlds.launcher.Launcher.mainWithExitCode(Launcher.java:414) at org.codehaus.plexus.classworlds.launcher.Launcher.main(Launcher.java:357) Caused by: org.apache.maven.plugin.MojoExecutionException: Unable to create features.xml file: org.apache.maven.plugin.MojoExecutionException: java.util.NoSuchElementException role: org.eclipse.aether.RepositorySystem roleHint: at org.apache.karaf.tooling.features.GenerateDescriptorMojo.execute(GenerateDescriptorMojo.java:364) at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:101) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:209) ... 19 more Caused by: org.apache.maven.plugin.MojoExecutionException: java.util.NoSuchElementException role: org.eclipse.aether.RepositorySystem roleHint: at org.apache.karaf.tooling.utils.DependencyHelperFactory.createDependencyHelper(DependencyHelperFactory.java:63) at org.apache.karaf.tooling.features.GenerateDescriptorMojo.execute(GenerateDescriptorMojo.java:346) ... 21 more Caused by: org.codehaus.plexus.component.repository.exception.ComponentLookupException: java.util.NoSuchElementException role: org.eclipse.aether.RepositorySystem roleHint: at org.codehaus.plexus.DefaultPlexusContainer.lookup(DefaultPlexusContainer.java:257) at org.codehaus.plexus.DefaultPlexusContainer.lookup(DefaultPlexusContainer.java:245) at org.codehaus.plexus.DefaultPlexusContainer.lookup(DefaultPlexusContainer.java:239) at org.apache.karaf.tooling.utils.DependencyHelperFactory.createDependencyHelper(DependencyHelperFactory.java:58) ... 22 more Caused by: java.util.NoSuchElementException at org.sonatype.guice.plexus.locators.RealmFilter$FilteredItr.next(RealmFilter.java:96) at org.sonatype.guice.plexus.locators.RealmFilter$FilteredItr.next(RealmFilter.java:54) at org.sonatype.guice.plexus.locators.DefaultPlexusBeans$Itr.next(DefaultPlexusBeans.java:60) at org.sonatype.guice.plexus.locators.DefaultPlexusBeans$Itr.next(DefaultPlexusBeans.java:48) at org.codehaus.plexus.DefaultPlexusContainer.lookup(DefaultPlexusContainer.java:253) ... 25 more
