Add Aspectj Runtime Library to project via .classpath file

Question

I have a python script that downloads the latest svn build, then converts the project to an aspectj project and adds the necessary libraries , except for the Aspectj Runtime Library. I have my script trying to add the library in to the .classpath file like so: <classpathentry exported="true" kind="con" path="/Users/rovimacmini/.m2/repository/org/aspectj/aspectjrt/1.8.0/aspectjrt-1.8.0.jar"/> but I get an error that the aspectjrt.jar isn't in the classpath. Does anyone know how I can add it via the .classpath file so that my java build path has the AspectJ Runtime Library in it like so:

I suggest you manually create an AspectJ project in Eclipse and just look at how Eclipse does it.

.project needs an 'ajbuilder' and an 'ajnature':

<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
    <name>AspectJ_Project</name>
    <comment></comment>
    <projects></projects>
    <buildSpec>
        <buildCommand>
            <name>org.eclipse.ajdt.core.ajbuilder</name>
            <arguments></arguments>
        </buildCommand>
    </buildSpec>
    <natures>
        <nature>org.eclipse.ajdt.ui.ajnature</nature>
        <nature>org.eclipse.jdt.core.javanature</nature>
    </natures>
</projectDescription>

.classpath needs a container ("con") classpath entry for the AspectJ runtime:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" path="src"/>
    <classpathentry kind="con" path="org.eclipse.ajdt.core.ASPECTJRT_CONTAINER"/>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/jre7"/>
    <classpathentry kind="output" path="bin"/>
</classpath>

Update: I also tried replacing the container entry provided by AJDT by a direct reference to a manually installed library in my local file system like this:

<classpathentry kind="lib" path="C:/Program Files/Java/AspectJ/lib/aspectjrt.jar"/>

It works nicely. So in this case it is not con, but lib type. In my experience it also is not necessary to set the exported property, you can just skip that one.
