IllegalAccessError: tried to access class while bu

We are building our android application with ANT. After upgrading to the latest SDK tools (Rev 21) and platform tools (Rev 16) along with setting the android:targetSdkVersion="17" in manifest.xml, our ant build fails with IllegalAccessError.

Strangely a double ant release succedes:

ant clean -> BUILD SUCCESSFUL
ant release - > BUILD FAILED
ant release - > BUILD SUCCESSFUL

While obviously what we actually want to do does not:

ant clean release - > BUILD FAILED

I already regenerated the build.xml with android update project -p . resulting in the same beaviour.

See ANT Output below:

release:

-pre-build:

-code-gen:

Maybe this will help someone when stumbling over this error:

I had the same issue, the reason were duplicated JARs in Ant's classpath. In my case, checkstyle-5.6-all.jar was added to the ANT_HOME\lib folder which contained the above mentioned classes, that caused some errors due to duplicate classes and access between them.

In this case, I suggest adding a local classpath variable for the Ant target which uses this library and keep the ANT_HOME\lib as clean as possible.

I faced with the same issue and after many hours solved it. Just use latest ANT (but not the one which is coming with Jenkins)
it seems that apache-ant-1.8.4 has some issues.
but after downloading the latest apache-ant-1.9.1 ant was able to build the project with library-project successfully

system's config where working ant build with library projects:

>ANT: 1.9.1
>Android SDK - 22 rev
>java 1.6.0_38
