Programmatically Installing Execution Environments, Adding them to Project Build Paths [message #1431519]

I would like to programmatically insert my custom execution environment as an added library in the Lua build path of my project, so that the users of our Eclipse application don't have to. The following code does exactly what I want:

LuaExecutionEnvironment ee = LuaExecutionEnvironmentManager.installLuaExecutionEnvironment("path/to/ee.zip");
List<IPath> eePath = LuaExecutionEnvironmentBuildpathUtil.getExecutionEnvironmentBuildPath(ee);

IBuildpathEntry e = DLTKCore.newLibraryEntry(eePath.get(0), IAccessRule.EMPTY_RULES, new IBuildpathAttribute[0], BuildpathEntry.INCLUDE_ALL, BuildpathEntry.EXCLUDE_NONE, false, true);
entrylist.add(e);				
project.setRawBuildpath(entrylist.toArray(new IBuildpathEntry[entrylist.size()]), null);

However the calls to installLuaExecutionEnvironment and getExecutionEnvironmentBuildPath are not API and give 'Discouraged Access' warnings. I'm wondering if there are other ways to install EE's and get their build paths without using private API's.

I know there is an extension point, executionEnvironment, but Eclipse isn't finding the schema when I try to open it and I don't know how to use it. Can it help me with custom EEs?

Hi,
LuaExecutionEnvironmentManager and LuaExecutionEnvironmentBuildpathUtil are not part of the API for now. Currently the API is really restrictive and we should probably think about make it more complete.

For the extension point, you're right. It exists but the are not schema on binary version of ldt plugin. We should probably deliver a source/SDK version of our plugins.
Waiting, you should have a look to the extension point here.
You could find some sample here and there.

If you ask this question, I suppose you implement some features on top of LDT. I don't know if you follow the story, but Koneki LDT will move on its own project LDT. The move will break the API because of package renaming. So this should be better to base your work on org.eclipse.ldt than org.eclipse.koneki.ldt. There're no release of LDT for now but we will release a M0 in few days which will just be a renaming/rebranding of Koneki LDT.
