问题
I had created a groovy project. It worked by itself.
After some additions I had to add a new jar of a new library into the imports.
While the whole workspace runs on Gradle, I added the appropriate Maven reference to the gradle.build file.
After running gradle cleanEclipse Eclipse the new library works OK.
But. All project references to the Groovy libraries disappeared. Foolish me, I had to put some references to them into the gradle.build, too.
The list of libraries:
groovy.util.slurpersupport
groovy.xml
org.codehaus.groovy.tools.xml
groovy.lang
But I don't know how to include them into gradle.build. I can't found them in maven repository. And even so, I have them installed in my Eclipse, and I should take these. And I can't google any help, because gradle groovy gives the results on how to call gradle from groovy, not vice versa.
Moving from plain Groovy to Gradle won't help, it is really about gradle support for calling a java library from groovy.
I have nothing against getting dependencies from Maven rep., but I don't know how to do it in my case - The problem is, that I have Eclipse 3.6. And I should use the last version of groovy for Eclipse 3.6. So, I have installed it from http://dist.codehaus.org/groovy/distributions/greclipse/snapshot/e3.6/. And I don't know what is the equivalent version in Maven - there is no info about it.

There was some error in the groovy in Eclipse installation. Now after running gradle cleanEclipse Eclipse while build.gradle has NO dependencies to groovy, almost everything runs OK, I only have to add the groovy nature to the project
