I was using the M6 SDK as well as the latest I build. I am having the same problem on both. When I create an example e4 project and run it without changing anything, I am getting no class found errors related to swt. I have only installed the minimalist e4 tools to get the workbench editor.

The log is below. I did check the product profile and the runtime generated config files to ensure that the SWT plugin is indeed a specified bundle, but I've not found anything to indicate that it is missing and it is present in all cases. I am also getting an error in the jdt because it does not find the SWT bundle. Only when I explicitly add the same swt bundle to the java build path do the error highlights in the jdt go away. Of course, I still get the runtime errors.

Any thoughts on the problem? For some reason, with M6+, I seem to be having little resolution issues everywhere that I cannot find the pattern--especially when trying to install the e.11 M6 bundles to get e4 tooling.

I tried leaving out theme bundles but I just get osgi bundle resolution errors instead of the errors below.

I found the problem after much digging.


On windows 7, x86_64 platfoms, it appears that the 4.1 SDK may set the target architecture to the ws=wpf and arch=x86 instead of ws=win32 arch=x86_64. While this is not wrong, the 4.1 SDK appears to only contain ws=win32 and arch=x86 in the distribution.

So the detection is correct in the default target platform but the plugins are not available. Somehow, there is no error signaled in plugin resolution. Perhaps it defaults back to x86 which then silently fails to load correctly...not sure.

I'm not sure if this is a bug or a feature but it was very hard to track down.

Many thanks. Had the same error x86_64 set as of another development machine, and it wouldn't work on a classical x86...

What's your build id? Is o.e.swt in your manifest and .product?

I was running into a similar issue, and turns out I was trying to start 32bit Juno with 64bit javaw.exe (I start eclipse with javaw.exe vs the eclipse.exe).

I had exactly the same problem (and Stacktrace) while executing some tycho-surefire-tests on our buildserver after upgrading from Luna M3 to M4.

The buildserver is Win64 the target environment win32.win32.x86

I've tried to include org.eclipse.swt.widgets as dependency on the test fragment and org.eclipse.swt.win32.win32.x86 as additional dependency on the tycho-surefire configuration but without success.

What helped in my case was to add
<environment>
<os>win32</os>
<ws>win32</ws>
<arch>x86_64</arch>
</environment>
to the build.

The actual problem was that I was accidentally running the tests with a 64bit VM instead of a 32bit VM.
