Eugene Kirpichov closed BEAM-2883. ---------------------------------- Resolution: Fixed Fix Version/s: Not applicable Fixed a long time ago. > Poor error message when forgetting to specify a Datastore project. > ------------------------------------------------------------------ > > Key: BEAM-2883 > URL: https://issues.apache.org/jira/browse/BEAM-2883 > Project: Beam > Issue Type: Bug > Components: io-java-gcp > Reporter: Scott Wegner > Assignee: Eugene Kirpichov > Priority: Minor > Fix For: Not applicable > > > From: > https://stackoverflow.com/questions/46155781/mojoexecutionexception-while-writing-to-bigquery > A Beam user using DatastoreIO.v1() encountered an error because their > pipeline didn't specify a Datastore project via > DatastoreIO.v1().read().withProject(..). But the error was not very > informative. Even when referencing the source code, it is difficult to trace > through the code due to use of AutoValue and ValueProvider. > The error was: > [ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.4.0:java > (default-cli) on project pubsub-bigquery: An exception occured while > executing the Java class. null: InvocationTargetException: projectId -> [Help > 1] > org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute > goal org.codehaus.mojo:exec-maven-plugin:1.4.0:java (default-cli) on project > pubsub-bigquery: An exception occured while executing the Java class. null > at > org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:212) > 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:116) > at > org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:80) > at > org.apache.maven.lifecycle.internal.builder.singlethreaded.SingleThreadedBuilder.build(SingleThreadedBuilder.java:51) > at > org.apache.maven.lifecycle.internal.LifecycleStarter.execute(LifecycleStarter.java:128) > at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:307) > at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:193) > at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:106) > at org.apache.maven.cli.MavenCli.execute(MavenCli.java:863) > at org.apache.maven.cli.MavenCli.doMain(MavenCli.java:288) > at org.apache.maven.cli.MavenCli.main(MavenCli.java:199) > 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:289) > at > org.codehaus.plexus.classworlds.launcher.Launcher.launch(Launcher.java:229) > at > org.codehaus.plexus.classworlds.launcher.Launcher.mainWithExitCode(Launcher.java:415) > at > org.codehaus.plexus.classworlds.launcher.Launcher.main(Launcher.java:356) > Caused by: org.apache.maven.plugin.MojoExecutionException: An exception > occured while executing the Java class. null > at org.codehaus.mojo.exec.ExecJavaMojo.execute(ExecJavaMojo.java:345) > at > org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:134) > at > org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:207) > ... 20 more > Caused by: java.lang.reflect.InvocationTargetException > 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.mojo.exec.ExecJavaMojo$1.run(ExecJavaMojo.java:293) > at java.lang.Thread.run(Thread.java:745) > Caused by: java.lang.NullPointerException: projectId > at > com.google.common.base.Preconditions.checkNotNull(Preconditions.java:787) > at > org.apache.beam.sdk.io.gcp.datastore.DatastoreV1$Read.validate(DatastoreV1.java:624) > at > org.apache.beam.sdk.Pipeline$ValidateVisitor.enterCompositeTransform(Pipeline.java:610) > at > org.apache.beam.sdk.runners.TransformHierarchy$Node.visit(TransformHierarchy.java:590) > at > org.apache.beam.sdk.runners.TransformHierarchy$Node.visit(TransformHierarchy.java:594) > at > org.apache.beam.sdk.runners.TransformHierarchy$Node.access$500(TransformHierarchy.java:276) > at > org.apache.beam.sdk.runners.TransformHierarchy.visit(TransformHierarchy.java:210) > at org.apache.beam.sdk.Pipeline.traverseTopologically(Pipeline.java:440) > at org.apache.beam.sdk.Pipeline.validate(Pipeline.java:552) > at org.apache.beam.sdk.Pipeline.run(Pipeline.java:296) > at org.apache.beam.sdk.Pipeline.run(Pipeline.java:283) > at org.druk.twc.tobq.DsToBQ.main(DsToBQ.java:126) > ... 6 more > [ERROR] > [ERROR] Re-run Maven using the -X switch to enable full debug logging. > [ERROR] > [ERROR] For more information about the errors and possible solutions, please > read the following articles: > [ERROR] [Help 1] > http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException -- This message was sent by Atlassian JIRA (v7.6.3#76005)
