I'm building a product based on Eclipse 3.8. The product compiles fine in Eclipse IDEs and with our newly-constructed Tycho build. However, when I add the Babel repository () to our target platform, Tycho complains with strange compilation errors realting to not finding SWT classes. The exact same target platform applied to Eclipse 3.8 SDK workspaces produces no compilation errors.
Here is some of what Tycho spits out:
[ERROR] Failed to execute goal org.eclipse.tycho:tycho-compiler-plugin:0.16.0:compile (default-compile) on project com.emc.xcp.common.ui: Compilation failure: Compilation failure:
[ERROR] F:\P4_Int\depot\Platform\XCPBuilder\Int\int_XCPBLD_2.0\staging\app\bundles\com.emc.xcp.common.ui\src\com\emc\xcp\common\ui\function\FunctionPalette.java:[0,0]

[ERROR] public class FunctionPalette extends AbstractTreePalette {
[ERROR] ^^^^^^^^^^^^^^^
[ERROR] The hierarchy of the type FunctionPalette is inconsistent


I noticed that all the Babel bundles are versioned 4.2.0, so I wondered if they are actually tested against Eclipse 3.8 plugins. I have confirmed (twice) that simply removing the Babel bundles from the target platform restores the build to success, so I'm pretty confused about how including Babel bundles could trigger compile errors referring to SWT.

Any ideas?

Thanks,
Eric

It appears I've run into https://bugs.eclipse.org/bugs/show_bug.cgi?id=391011
There is a patch awaiting review: https://git.eclipse.org/r/#/c/8163/
