Hello, I'm hoping someone may be able to assist me with a Maven Site generation issue I've been having ever since I added a fourth module to my multi-module build. The issue appears to be linked to the maven-javadoc-plugin and I'm hoping someone here may have some insight into how I may be able to fix this problem.
I am running mvn site with MAVEN_OPTS=-Xmx512m as the site goal runs out of memory without this set. However, this appears to conflict with the javadoc reports as I am gettting the following stack trace: [INFO] Trace org.apache.maven.lifecycle.LifecycleExecutionException: Error during page generation at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoals(DefaultLifecycleExecutor.java:703) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalWithLifecycle(DefaultLifecycleExecutor.java:540) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoal(DefaultLifecycleExecutor.java:519) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalAndHandleFailures(DefaultLifecycleExecutor.java:371) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeTaskSegments(DefaultLifecycleExecutor.java:332) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.execute(DefaultLifecycleExecutor.java:181) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:356) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:137) at org.apache.maven.cli.MavenCli.main(MavenCli.java:362) at org.apache.maven.cli.compat.CompatibleMain.main(CompatibleMain.java:41) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.codehaus.classworlds.Launcher.launchEnhanced(Launcher.java:315) at org.codehaus.classworlds.Launcher.launch(Launcher.java:255) at org.codehaus.classworlds.Launcher.mainWithExitCode(Launcher.java:430) at org.codehaus.classworlds.Launcher.main(Launcher.java:375) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:110) Caused by: org.apache.maven.plugin.MojoExecutionException: Error during page generation at org.apache.maven.plugins.site.SiteMojo.execute(SiteMojo.java:105) at org.apache.maven.plugin.DefaultPluginManager.executeMojo(DefaultPluginManager.java:483) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoals(DefaultLifecycleExecutor.java:678) ... 22 more Caused by: org.apache.maven.doxia.siterenderer.RendererException: Error rendering Maven report: Error occurred during initialization of VM, try to reduce the Java heap size for the MAVEN_OPTS environnement variable using -Xms:<size> and -Xmx:<size>. at org.apache.maven.plugins.site.ReportDocumentRenderer.renderDocument(ReportDocumentRenderer.java:149) at org.apache.maven.doxia.siterenderer.DefaultSiteRenderer.renderModule(DefaultSiteRenderer.java:269) at org.apache.maven.doxia.siterenderer.DefaultSiteRenderer.render(DefaultSiteRenderer.java:101) at org.apache.maven.plugins.site.SiteMojo.renderLocale(SiteMojo.java:133) at org.apache.maven.plugins.site.SiteMojo.execute(SiteMojo.java:100) ... 24 more Caused by: org.apache.maven.reporting.MavenReportException: Error occurred during initialization of VM, try to reduce the Java heap size for the MAVEN_OPTS environnement variable using -Xms:<size> and -Xmx:<size>. at org.apache.maven.plugin.javadoc.AbstractJavadocMojo.getModulesLinks(AbstractJavadocMojo.java:4706) at org.apache.maven.plugin.javadoc.AbstractJavadocMojo.addLinkofflineArguments(AbstractJavadocMojo.java:3226) at org.apache.maven.plugin.javadoc.AbstractJavadocMojo.addStandardDocletOptions(AbstractJavadocMojo.java:4041) at org.apache.maven.plugin.javadoc.AbstractJavadocMojo.executeReport(AbstractJavadocMojo.java:1803) at org.apache.maven.plugin.javadoc.JavadocReport.generate(JavadocReport.java:124) at org.apache.maven.plugins.site.ReportDocumentRenderer.renderDocument(ReportDocumentRenderer.java:139) ... 28 more Caused by: org.apache.maven.shared.invoker.MavenInvocationException: Error occurred during initialization of VM, try to reduce the Java heap size for the MAVEN_OPTS environnement variable using -Xms:<size> and -Xmx:<size>. at org.apache.maven.plugin.javadoc.JavadocUtil.invokeMaven(JavadocUtil.java:1081) at org.apache.maven.plugin.javadoc.AbstractJavadocMojo.getModulesLinks(AbstractJavadocMojo.java:4689) ... 33 more The javadoc plugin version being used is 2.6.1.
