Question

I have a main android app which has 2 jars in it’s libs folder. This android app includes a Java Source Project which has about 4 jars in it’s libs folder.

In the build.xml I have copied from android’s build.xml the ‘target name=”-compile”>’.

and added this:

    <do-only-if-manifest-hasCode elseText="hasCode = false. Skipping..." >

        <!-- merge the project's own classpath and the tested project's classpath -->

        <path id="project.javac.classpath" >

            <path refid="project.all.jars.path" />

            <path refid="tested.project.classpath" />
        </path>
 <javac
  bootclasspathref="project.target.class.path"
  classpathref="project.javac.classpath"
  debug="true"
  destdir="${out.classes.absolute.dir}"
  encoding="${java.encoding}"
  extdirs=""
  fork="${need.javac.fork}"
  includeantruntime="false"
  source="${java.source}"
  target="${java.target}"
  verbose="${verbose}" >
  <src path="${source.absolute.dir}" />
  <src path="${gen.absolute.dir}" />
  <src path="${javaproject.dir}" /> #THIS IS WHAT I ADDED which is defined in ANT.PROPERTIES
  <compilerarg line="${java.compilerargs}" />
</javac>

So it references the java source project. The problem happens with the java source project’s jars which are in folder libs.
How do I also include them?

ps. copying them to android project’s libs folder is not an option.

You have the following:

<javac
     bootclasspathref="project.target.class.path"
     classpathref="project.javac.classpath"
     debug="true"
     destdir="${out.classes.absolute.dir}"
     encoding="${java.encoding}"
     extdirs=""
     fork="${need.javac.fork}"
     includeantruntime="false"
     target="${java.target}"
     verbose="${verbose}"

     source="${java.source}">

     <src path="${source.absolute.dir}" />
     <src path="${gen.absolute.dir}" />
     <src path="${javaproject.dir}" /> #THIS IS WHAT I ADDED which is defined in ANT.PROPERTIES

    <compilerarg line="${java.compilerargs}" />
</javac>

Notice you’ve specified both the source parameter and the <src path> sub-entity. Also notice that you have a reference to javaproject.dir. What is this directory? Is it the source of the other project, the other project’s main directory, or something else?

First, you shouldn’t use both <src path> and the srcdir parameters in your <javac> command. If you need only a single source directory path, you can use either the srcdir parameter of the <javac> task, or the <src path> sub-entity. If you have more than one, you should not use srcdir, and only use the <src path> sub-entity.

Now back to your question…

If I understand you correctly, you want to specify multiple classpath folders in your <javac> task. You can do this by removing the classpath or classpathref parameters of the <javac> command, and simply specify multiple <classpath path> sub-entities like you do with source directories.

I think you want something like this:

<javac
     bootclasspathref="project.target.class.path"
     debug="true"
     destdir="${out.classes.absolute.dir}"
     encoding="${java.encoding}"
     extdirs=""
     fork="${need.javac.fork}"
     includeantruntime="false"
     target="${java.target}"
     verbose="${verbose}">

     <!-- Here I can specify multiple classpaths: -->
     <!-- Either classpath references, or classpath elements -->
     <classpath refid="project.javac.classpath"/>
     <classpath refid="some.other.classpath.reference"/>
     <classpath path="${some.actual.directory.with.jars}"/>

     <src path="${java.source}">
     <src path="${source.absolute.dir}" />
     <src path="${gen.absolute.dir}" />
     <!-- <src path="${javaproject.dir}" />  Is this correct? -->

     <compilerarg line="${java.compilerargs}" />
</javac>
