问题
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:
[mergemanifest] Merging AndroidManifest files into one.
[mergemanifest] Manifest merger disabled. Using project manifest only.

回答1:
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
