Subject DO NOT REPLY [Bug 44689] New: NPE when running multiple targets in Ant
Date Thu, 27 Mar 2008 13:57:19 GMT
https://issues.apache.org/bugzilla/show_bug.cgi?id=44689

           Summary: NPE when running multiple targets in Ant
           Product: Ant
           Version: 1.7.0
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: critical
          Priority: P2
         Component: Core
        AssignedTo: notifications@ant.apache.org
        ReportedBy: rbuck@verisign.com


Run the following build file as "ant init clean" and you ALWAYS get an NPE. I
have seen this behavior in several scenarios, and basically one cannot run
multiple build targets from the command line without Ant blowing up.

<?xml version="1.0"?>
<project name="AntNPE" default="init">
  <target name="init">
    <echo id="test">test</echo>
  </target>
  <target name="clean" depends="init"/>
</project>
