Subject AW: include via script task
Date Tue, 04 Dec 2012 07:17:06 GMT
Hi Jan,

thanks for the code. I thought there was a "clean API way" to do this, but
I'll try your approach.

Regards.

Betreff: AW: include via script task

I played a little bit and the solution is to tweak the Ant API ...
This examples works for me, but using <import> or <include> via this way is
not recommended/supported ;-) Have fun - but be aware of "side effects" ...


Cheers
Jan


imported.xml
<project name="imported">
  <echo>Hello from imported file: ${ant.file}</echo> </project>  

build.xml
<project>

  <script language="beanshell">
      <![CDATA[
          import org.apache.tools.ant.taskdefs.ImportTask;
          import org.apache.tools.ant.Target;

          // Create an initialize the <include> (which is the same as
<import>,
          // see taskdef-mapping:
http://svn.apache.org/repos/asf/ant/core/trunk/src/main/org/apache/tools/ant
/taskdefs/defaults.properties  
          ImportTask includeTask = project.createTask("include");
          
          // Set the file to include
          includeTask.setFile("./imported.xml");
          
          // now tweak the Ant API by setting a non-null owning Target with
an empty name 
          //

          //    ...
          //    if (getOwningTarget() == null
          //      || !"".equals(getOwningTarget().getName())) {
          //      throw new BuildException("import only allowed as a
top-level task");
          //    }
          Target helpTarget = new Target();
          helpTarget.setName("");
          includeTask.setOwningTarget(helpTarget);
          
          // For further execution the <import> requires to now its
location, so we
          // pass the <script> ones.
          includeTask.setLocation(self.getLocation());
          
          // and go ...
          includeTask.perform();
      ]]>
  </script>
  
</project>

Betreff: include via script task

Hi all,

 

I'm trying to call ant's include task inside a <script> element, like 

  

<script language="beanshell">

    <![CDATA[

        import org.apache.tools.ant.taskdefs.ImportTask;

       

        ImportTask includeTask = project.createTask("include");

        includeTask.setFile("./global-properties.xml");

        includeTask.perform();

    ]]>

</script>

 

This fails with the error  "import only allowed as a top-level task".

 

Anyone knows how to create a "top level task" inside a <script> element ? 

 

Thanks,

 

Steve.
