http://issues.apache.org/bugzilla/show_bug.cgi?id=32216 Using parse method of ProjectHelper causes import to fail Summary: Using parse method of ProjectHelper causes import to fail Product: Ant Version: 1.6.2 Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Normal Priority: Other Component: Core tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I have code to programmatically invoke Ant that uses the deprecated method configureProject and works fine: Project proj = new Project(); proj.fireBuildStarted(); proj.init(); try { ProjectHelper.configureProject(proj, new File("build.xml")); proj.executeTarget(proj.getDefaultTarget()); proj.fireBuildFinished(null); } catch (BuildException e) { proj.fireBuildFinished(e); throw e; } I replaced the line: ProjectHelper.configureProject(proj, new File("build.xml")); with the non-deprecated version: ProjectHelper helper = ProjectHelper.getProjectHelper(); helper.parse(proj, new File("build.xml")); This worked fine until I had a build.xml file with an import statement in it. e.g. <project name="test" default="test"> <import file="build2.xml" /> <target name="test"> <echo message="Hello World" /> </target> </project> This caused the import task to throw a NullPointer exception in the execute method: C:\ASCv2Workspace\test\build.xml:2: java.lang.NullPointerException at org.apache.tools.ant.Task.perform(Task.java:373) at org.apache.tools.ant.Target.execute(Target.java:341) at org.apache.tools.ant.helper.ProjectHelper2.parse(ProjectHelper2.java:133) at Test.main(Test.java:31) --- Nested Exception --- java.lang.NullPointerException at org.apache.tools.ant.taskdefs.ImportTask.execute(ImportTask.java:104) at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:275) at org.apache.tools.ant.Task.perform(Task.java:364) at org.apache.tools.ant.Target.execute(Target.java:341) at org.apache.tools.ant.helper.ProjectHelper2.parse(ProjectHelper2.java:133) at Test.main(Test.java:31) Exception in thread "main" I checked, and the null pointer was thrown by: Vector importStack = helper.getImportStack(); because helper is null. Comparing the configureProject deprecated method and the parse method, it looks like parse never sets the "ant.projectHelper" property. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
