Subject cvs commit: jakarta-ant/src/main/org/apache/tools/ant/taskdefs Jar.java Manifest.java Zip.java
Date Wed, 01 Aug 2001 12:56:23 GMT
conor       01/08/01 05:56:23

  Modified:    src/main/org/apache/tools/ant/taskdefs Jar.java
                        Manifest.java Zip.java
  Log:
  Allow manifests of Jar files to be specified in-line. This allows the
  use of Ant properties in the manifest. The inline manifest will be
  merged with any external file manifests. Example usage
  
      <jar jarfile="taskjar2.jar" basedir="." manifest="manifest.mf">
        <include name="src/**/*"/>
        <manifest>
          <attribute name="Built-By" value="${user.name}"/>
        </manifest>
      </jar>
