Ant immutable properties to mutable

问题:

i have a problem. I'm use antrun plugin for maven and do next: i have folder and subfolders(I do not know what are called sub-folders and their number) and i'm do archive for this subfolders with their name(subfolder name - "1", archive name - "1.acp").

               <tasks>
                  <taskdef resource="net/sf/antcontrib/antlib.xml" classpath="${settings.localRepository}/ant-contrib/ant-contrib/1.0b3/ant-contrib-1.0b3.jar" />
                  <taskdef resource="net/sf/antcontrib/antcontrib.properties" classpath="${settings.localRepository}/ant-contrib/ant-contrib/1.0b3/ant-contrib-1.0b3.jar" />
                  <for param="file">
                      <path>
                          <dirset dir="src/main/bootstrap" includes="/*" />
                      </path>
                      <sequential>
                          <basename property="dir" file="@{file}" />
                          <zip destfile="${project.build.outputDirectory}/alfresco/extension/agilent/${dir}.acp" basedir="@{file}" />
                      </sequential>
                  </for>
              </tasks>

But property dir is immutable!!! And all archive has name "1.acp". How to make this property mutable or do this another way?

回答1:

You may use a 1.8 Ant's Local task

In your case:

<sequential>
  <local name="dir"/>
  <basename property="dir" file="@{file}"/>
  <zip
    destfile="${project.build.outputDirectory}/alfresco/extension/agilent/${dir}.acp" 
    basedir="${dir}"
  />
</sequential>

回答2:

You can use the var task from ant contrib.

The property unset, lets you reset values(example from above link):

    <property name="x" value="6"/>
    <echo>${x}</echo>   <!-- will print 6 -->
    <var name="x" unset="true"/>
    <property name="x" value="12"/>
    <echo>${x}</echo>   <!-- will print 12 -->

So you will have to fix it to:

 <sequential>
   <var name="dir" unset="true"/>
   <basename property="dir" file="@{file}" />
   <zip destfile="${project.build.outputDirectory}/alfresco/extension/agilent/${dir}.acp" basedir="@{file}" />
 </sequential>
