Hello,
I get strange behaviour of the editor when rebuild is invoked.
Problem is following: I have exported plugins to new Eclipse application. Everything works fine, just Clean action takes long time. At least half of this time Progress view says: "Compiling SomeXtendClassName.xtend"... I don't understand, why are the Xtend files exported to plugins. As far as I understand the process, content of Xtend classes are transformed to Java classes and they are compiled to .class files. These class files are to be used in the runtime, isn't it? Why are the Xtend files always recompiled? How can I avoid it?
Thank you & Best regards,
Michal

Hi,

imply do not add them to the plugin.
if they are on the classpath they are ompiled
this goes with std eclipse means.
(includes/excludes in the source folder)

The problem was, that Eclipse copies all resources with non-java extension automatically to bin folder. For most basic users of Xtext would be probably best practice to avoid this. I found this solution:
Right click on the main project -> Properties -> Java Compiler -> Builder -> Enable project specific settings (tick) -> Output folder -> Filtered resources (write in following: "*.xtend,*.mwe2,*.xtext") and Clean the project...
Regards,
Michal
