http://nagoya.apache.org/bugzilla/show_bug.cgi?id=15994 The cvstagdiff taskdef errors when no committed files have occurred in CVS in given interval Summary: The cvstagdiff taskdef errors when no committed files have occurred in CVS in given interval Product: Ant Version: 1.5.1 Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Major Priority: Other Component: Core tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] When I use the <cvstagdiff> taskdef and supply a startdate and enddate interval in which no commits have occurred in CVS, the cvstagdiff taskdef stack dumps and quits the build. See the ant log excerpt below. I have writen a small fix for this and rebuilt Ant 1.5.1 locally and the fix cures the problem. The problem is that the method 'parseRDiff' (in CvsTagDiff.java line 354) assumes the CVS supplied rdiff file contains at least one line when it may contain none. I have changed line 354 from: int headerLength = getHeaderLength(line); to: int headerLength = (line == null) ? 0 : getHeaderLength(line); ------------------------ Ant's log.xml ---------------- <task location="file:C:/CruiseControl/bcitoolkitbuild/build.xml:126: " name="cvstagdiff" time="2 seconds"> <message priority="debug"><![CDATA[Cvs command is rdiff -s -D '2003-01-10 12:15:19' -D '2003-01-10 14:50:31' bt_toolkit]]></message> <message priority="debug"><![CDATA[Execute:Java13CommandLauncher: Executing 'cvs' with arguments: '-d:ext:[EMAIL PROTECTED]:/cvs/bcisource' 'rdiff' '-s' '-D' '2003-01-10 12:15:19' '-D' '2003-01-10 14:50:31' 'bt_toolkit' The ' characters around the executable and arguments are not part of the command. ]]></message> <message priority="debug"><![CDATA[retCode=0]]></message> </task> </target> <stacktrace><![CDATA[java.lang.NullPointerException at org.apache.tools.ant.taskdefs.cvslib.CvsTagDiff.getHeaderLength (CvsTagDiff.java:428) at org.apache.tools.ant.taskdefs.cvslib.CvsTagDiff.parseRDiff (CvsTagDiff.java:354) at org.apache.tools.ant.taskdefs.cvslib.CvsTagDiff.execute(CvsTagDiff.java:326) at org.apache.tools.ant.Task.perform(Task.java:319) at org.apache.tools.ant.Target.execute(Target.java:309) at org.apache.tools.ant.Target.performTasks(Target.java:336) at org.apache.tools.ant.Project.executeTarget(Project.java:1306) at org.apache.tools.ant.Project.executeTargets(Project.java:1250) at org.apache.tools.ant.Main.runBuild(Main.java:610) at org.apache.tools.ant.Main.start(Main.java:196) at org.apache.tools.ant.Main.main(Main.java:235) ]]></stacktrace> ----------------------- -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
