I can't ProGuard my extensions?

Open Source Development Extension Development

When running ant extensions -Dproguard=1 in CMD, I am unable to ProGuard my extensions. This is the error I'm getting: Can't read [C:\Users\xx\Desktop\extension-template-master\lib\appinventor\apksigner.jar] (only DEFLATED entries can have EXT descriptor).

Since no one could help me, I explored like Dora to fix the issue myself. I added these lines to the build.xml file below these lines...

<injar  file="${ExternalComponent-class.dir}/${extensionClassFolder}.jar" />
<outjar file="${ExternalComponent-class.dir}/${extensionClassFolder}_p.jar" />

I removed every <libraryJar element, but kept the one for AndroidRuntime.jar... This is what I replaced the previous lines for...

<libraryjar>
    <fileset dir="${public.deps.dir}">
        <include name="**/*.jar"/>
        <exclude name="apksigner.jar"/>
    </fileset>
</libraryjar>

Or you should just be able to remove the apksigner.jar from the ProGuard area. At the end it should look like this...

<target name="ProGuard" unless="skipProguard">
    <taskdef resource="proguard/ant/task.properties"
             classpath="${lib.dir}/proguard/proguard.jar" />
    <proguard printmapping="${public.build.dir}/proguard.map"
              overloadaggressively="on"
              configuration="${lib.dir}/proguard/proguard.cfg"
              ignorewarnings="true">

      <injar  file="${ExternalComponent-class.dir}/${extensionClassFolder}.jar" />
      <outjar file="${ExternalComponent-class.dir}/${extensionClassFolder}_p.jar" />

      <!-- FOR DEVELOPER: Add the needed libraries for your extension right here
                          like the ones above, just after copying them to the deps
                          directory.
      <libraryjar file="${public.deps.dir}/my-awesome-library.jar" /> -->
      <libraryjar>
        <fileset dir="${public.deps.dir}">
          <include name="**/*.jar"/>
          <exclude name="apksigner.jar"/>
        </fileset>
      </libraryjar>
      
      <libraryjar file="${public.build.dir}/AndroidRuntime.jar" />

      <dontnote filter="proguard.configuration.ConfigurationLogger" />
      <adaptresourcefilecontents filter="proguard/ant/task.properties" />
    </proguard>

    <delete file="${ExternalComponent-class.dir}/${extensionClassFolder}.jar" />
    <move file="${ExternalComponent-class.dir}/${extensionClassFolder}_p.jar"
          tofile="${ExternalComponent-class.dir}/${extensionClassFolder}.jar" />
  </target>

I removed the apksigner.jar library from inclusion since when compiling extension, you don't need it.

If you used the extension-template-master from Github

<libraryjar>
  <fileset dir="lib">
    <exclude name="appinventor/apksigner.jar"/>
    <include name="**/*.jar"/>
    <include name="**/*.aar"/>
    <exclude name="*/dx.jar"/>
  </fileset>
</libraryjar>

Or it will look like...

<target name="ProGuard" unless="skipProguard">
    <taskdef resource="proguard/ant/task.properties"
             classpath="lib/proguard/proguard.jar" />
    <proguard printmapping="out/${extensionClassFolder}-proguard.map"
              overloadaggressively="on"
              configuration="lib/proguard/proguard.cfg"
              ignorewarnings="true">

      <injar  file="${ExternalComponent-class.dir}/${extensionClassFolder}.jar" />
      <outjar file="${ExternalComponent-class.dir}/${extensionClassFolder}_p.jar" />

      <libraryjar>
        <fileset dir="lib">
          <exclude name="appinventor/apksigner.jar"/>
          <include name="**/*.jar"/>
          <include name="**/*.aar"/>
          <exclude name="*/dx.jar"/>
        </fileset>
      </libraryjar>

      <dontnote filter="proguard.configuration.ConfigurationLogger" />
      <adaptresourcefilecontents filter="proguard/ant/task.properties" />
    </proguard>

    <delete file="${ExternalComponent-class.dir}/${extensionClassFolder}.jar" />
    <move file="${ExternalComponent-class.dir}/${extensionClassFolder}_p.jar"
          tofile="${ExternalComponent-class.dir}/${extensionClassFolder}.jar" />
  </target>
