gary emiddio bello commented on NETBEANS-457: --------------------------------------------- to reproduce git checkout jGit source from [https://github.com/eclipse/jgit.git]; modify version minimums in top level pom.xml and org.eclipse.jgit.packaging\pom.xml to maven version supported in bundled maven in nb9 - which is 3.3.9, from 3.5.2 in orig pom.xml files. verify command line maven 3.3.9 successfully build jGit - it does for me. then try to build jGit from netbeans - open jGit project with nb9. do build - clean, build from nb9. exception will occur. I spent day+ trying to debug/figure out but was unsuccessful. 1st NPE is due to a startFold method call where maven\src\org\netbeans\modules\maven\execute\CommandLineOutputHandler.java line 350 calls startFold - but even if that line is commented out and also line 354 - with intention of not creating folds in the output window a NPE is eventually thrown in method trimTree after 'start = currentTreeNode.getStartEvent();' line since start will be null; The tree which is built to manage folds is not as expected by existing code. > maven build exception > --------------------- > > Key: NETBEANS-457 > URL: https://issues.apache.org/jira/browse/NETBEANS-457 > Project: NetBeans > Issue Type: Bug > Components: apisupport - Maven > Affects Versions: 9.0 > Environment: Product Version: Apache NetBeans IDE Dev (Build > 20180309-unknown-revn) > Java: 9.0.4; Java HotSpot(TM) 64-Bit Server VM 9.0.4+11 > Runtime: Java(TM) SE Runtime Environment 9.0.4+11 > System: Windows 10 version 10.0 running on amd64; Cp1252; en_US (nb) > User directory: C:\Users\gary\AppData\Roaming\NetBeans\dev > Cache directory: C:\Users\gary\AppData\Local\NetBeans\Cache\dev > Reporter: gary emiddio bello > Priority: Major > > > error while building jgit from > [https://github.com/eclipse/jgit.git] > java.lang.AssertionError > at > org.netbeans.modules.maven.execute.cmd.ExecutionEventObject$Tree.startFold(ExecutionEventObject.java:174) > at > org.netbeans.modules.maven.execute.CommandLineOutputHandler$Output.run(CommandLineOutputHandler.java:350) > at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:1418) > at > org.netbeans.modules.openide.util.GlobalLookup.execute(GlobalLookup.java:45) > at org.openide.util.lookup.Lookups.executeWith(Lookups.java:278) > at > org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:2033) > Caused: org.openide.util.RequestProcessor$SlowItem: task failed due to > at org.openide.util.RequestProcessor.post(RequestProcessor.java:395) > at > org.netbeans.modules.maven.execute.CommandLineOutputHandler.setStdOut(CommandLineOutputHandler.java:146) > at > org.netbeans.modules.maven.execute.MavenCommandLineExecutor.run(MavenCommandLineExecutor.java:280) > [catch] at > org.netbeans.core.execution.RunClassThread.run(RunClassThread.java:128) -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@netbeans.apache.org For additional commands, e-mail: commits-h...@netbeans.apache.org For further information about the NetBeans mailing lists, visit: https://cwiki.apache.org/confluence/display/NETBEANS/Mailing+lists
