[Solved] Xtext 2.2.1 project build stucks at "Validate resources" [message #890025]

Hello,

I have a hugh Xtext 2.2.1 project and the build process repeatly stucks at "Validate resources". The process bar for "Build Project" just stays the same for hours.

Can somebody give me a hint whats going wrong here?

BTW: The project has a language definition with about 150 gramar items. The code generator consists of about 40 Xtend2 classes (~650 kB of Xtend2 code).

Regards,
Jonatan

Hello,

I have just tried Eclipse Juno RC1 with Xtext 2.3M7 => same effects.

Is it when building the Xtend code or when executing it? If your Xtend
code contains a lot of closures with type inference for the parameters,
it can really help to declare the types explicitly.

Did you try to (significantly) increase heap memory?

Hello Jan,

I do not really know what Eclipse is doing in the background while the project is building. I guess it is during building Xtend to Java code. Compiling and executing the resulting java code (our generator) is no problem.

Our Xtend code makes heavy use of closures, and I guess most time with type inference. I will try to remove the type inference.

I have tried heap sizes between 512m and 4096m. I guess more heap space helps a little bit, but not significantly.

Thx,
Jonatan

Hello,

I have removed nearly all type inference from my project. Now it feels much faster.

Thx,
Jonatan

Jonatan,

yes, that is a unfortunate workaround. It is usually sufficient to
explicitly state the types of parameters in lambda expressions.

Sebastian

Addition: The build also stucks at validate resources, when the generated xtext model classes are missing.

We do not commit the src-gen folder to the repository. Thus having a clean workspace, all those generated java classes are missing. Try to run the mwe2 workflow in order to let xtext generate these will trigger a workspace build. This ends up in the same problem.

The workaround here is just disable the Xtext project builder. Run the mwe2 workflow. Reenable the Xtext project builder afterwards.

Have you solved this issues with Juno?

Jonatan

Yes, compile problems are handled more gracefully in Juno. At least the
situation should be better than with former versions.

Ooops, really? Could you file a bug for this?
