[ http://jira.codehaus.org/browse/MNG-2459?page=all ]
Carlos Sanchez closed MNG-2459. ------------------------------- Assignee: Carlos Sanchez Resolution: Won't Fix You probably need to make java task to fork the jvm, see ant documentation. In any case this is not a maven bug. > Problem parsing XML in code run using antrun plugin > --------------------------------------------------- > > Key: MNG-2459 > URL: http://jira.codehaus.org/browse/MNG-2459 > Project: Maven 2 > Issue Type: Bug > Components: Ant tasks > Affects Versions: 2.0.4 > Environment: Red Hat Enterprise Linux WS release 4 (Nahant Update 3) > java version "1.5.0_06" > Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05) > Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing) > Reporter: Kris Nuttycombe > Assigned To: Carlos Sanchez > Attachments: antrun-log4j-xml-test.tgz > > > I'm not certain whether this is an antrun problem or a log4j problem, but > considering that the same application run from the command line has no > problems, I'm going to point to antrun as the first possible culprit. > This error occurs when I attempt to use the antrun plugin to run a standalone > Java program that is, for deployment, packaged as a jar-with-dependencies jar > using the assembly plugin. I use antrun during development for the purpose of > giving me the benefit of the classpath information from the POM; if there's a > better way of doing this I'd be happy to work around the problem. > The error appears to occur when log4j attempts to parse an XML configuration > file using the DOMConfigurator. It appears that the DocumentBuilderFactory > package name is being prepended with "com.sun." when the application is run > using the antrun plugin. Is there some aspect of Maven or of the antrun > plugin that is altering the XML parsing environment? > [java] javax.xml.parsers.FactoryConfigurationError: Provider > com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl could not > be instantiated: java.lang.NullPointerException > [java] at > org.apache.tools.ant.taskdefs.ExecuteJava.execute(ExecuteJava.java:180) > [java] at org.apache.tools.ant.taskdefs.Java.run(Java.java:710) > [java] at > org.apache.tools.ant.taskdefs.Java.executeJava(Java.java:178) > [java] at org.apache.tools.ant.taskdefs.Java.execute(Java.java:84) > [java] at > org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:275) > [java] at org.apache.tools.ant.Task.perform(Task.java:364) > [java] at org.apache.tools.ant.Target.execute(Target.java:341) > [java] at > org.apache.maven.plugin.antrun.AbstractAntMojo.executeTasks(AbstractAntMojo.java:108) > [java] at > org.apache.maven.plugin.antrun.AntRunMojo.execute(AntRunMojo.java:83) > [java] at > org.apache.maven.plugin.DefaultPluginManager.executeMojo(DefaultPluginManager.java:412) > [java] at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoals(DefaultLifecycleExecutor.java:534) > [java] at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeStandaloneGoal(DefaultLifecycleExecutor.java:488) > [java] at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoal(DefaultLifecycleExecutor.java:458) > [java] at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalAndHandleFailures(DefaultLifecycleExecutor.java:306) > [java] at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeTaskSegments(DefaultLifecycleExecutor.java:273) > [java] at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.execute(DefaultLifecycleExecutor.java:140) > [java] at > org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:322) > [java] at > org.apache.maven.DefaultMaven.execute(DefaultMaven.java:115) > [java] at org.apache.maven.cli.MavenCli.main(MavenCli.java:256) > [java] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > [java] at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) > [java] at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) > [java] at java.lang.reflect.Method.invoke(Method.java:585) > [java] at > org.codehaus.classworlds.Launcher.launchEnhanced(Launcher.java:315) > [java] at org.codehaus.classworlds.Launcher.launch(Launcher.java:255) > [java] at > org.codehaus.classworlds.Launcher.mainWithExitCode(Launcher.java:430) > [java] at org.codehaus.classworlds.Launcher.main(Launcher.java:375) > [java] Caused by: javax.xml.parsers.FactoryConfigurationError: Provider > com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl could not > be instantiated: java.lang.NullPointerExce > ption > [java] at > javax.xml.parsers.DocumentBuilderFactory.newInstance(DocumentBuilderFactory.java:104) > [java] at > org.apache.log4j.xml.DOMConfigurator.doConfigure(DOMConfigurator.java:644) > [java] at > org.apache.log4j.xml.DOMConfigurator.doConfigure(DOMConfigurator.java:616) > [java] at > org.apache.log4j.xml.DOMConfigurator.doConfigure(DOMConfigurator.java:584) > [java] at > org.apache.log4j.xml.DOMConfigurator.configure(DOMConfigurator.java:687) > [java] at gov.noaa.eds.sdif.SdifRunner.main(SdifRunner.java:45) > [java] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > [java] at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) > [java] at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) > [java] at java.lang.reflect.Method.invoke(Method.java:585) > [java] at > org.apache.tools.ant.taskdefs.ExecuteJava.run(ExecuteJava.java:202) > [java] at > org.apache.tools.ant.taskdefs.ExecuteJava.execute(ExecuteJava.java:134) > [java] ... 26 more > The attached test setup can be run using the following call from the command > line: > mvn -DlogConfig=src/test/resources/log4j_conf.xml compile antrun:run -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.codehaus.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
