http://nagoya.apache.org/bugzilla/show_bug.cgi?id=22705 ant 1.6alpha (and possibly earlier) requires JDK 1.4 Summary: ant 1.6alpha (and possibly earlier) requires JDK 1.4 Product: Ant Version: 1.6Alpha (nightly) Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Normal Priority: Other Component: Core tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Contrary to the statement on the ant welcome page, there is a dependency on having JDK 1.4 or higher. The problem appears when I use the <description> tag to provide a project-wide description, and I also have several targets that use the description attribute. I run "ant -projecthelp" and get a NoSuchMethodError: % ant -f customizations-build.xml -projecthelp Buildfile: customizations-build.xml java.lang.NoSuchMethodError at org.apache.tools.ant.types.Description.concatDescriptions (Description.java:123) at org.apache.tools.ant.types.Description.getDescription (Description.java:104) at org.apache.tools.ant.Project.getDescription(Project.java:721) at org.apache.tools.ant.Main.printDescription(Main.java:823) at org.apache.tools.ant.Main.runBuild(Main.java:599) at org.apache.tools.ant.Main.start(Main.java:198) at org.apache.tools.ant.Main.main(Main.java:245) I'm using ant 1.6alpha, but if my diagnosis of the problem is correct, this problem should show up with later versions of ant 1.5.x. In revision 1.9 of Description.java, the following snippet of code showed up: private static void concatDescriptions(Project project, Target t, StringBuffer description) { if( t==null ) return; Vector tasks= findElementInTarget(project, t, "description"); if( tasks==null ) return; for( int i=0; i<tasks.size(); i++ ) { Task task=(Task)tasks.elementAt(i); if( ! ( task instanceof UnknownElement)) { continue; } UnknownElement ue=((UnknownElement)task); StringBuffer descComp=ue.getWrapper().getText(); if( descComp != null ) { ******************************************************* description.append( descComp ); ******************************************************* } } } The offending line is the one surrounded by *'s. The problem is that the StringBuffer method "StringBuffer append(StringBuffer)" wasn't added until JDK 1.4. Previously, there were many other variants of append(), but not that particular one. This problem can easily be worked around by changing the line to "description.append( new String(descComp) );" --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
