I'm trying to compile the javadocs for my application, and for some reason it throws errors while compiling like this:
/Users/Sander/.gradle/caches/artifacts-23/filestore/com.google.gwt/gwt-user/2.4.0/jar/949dcb5d14cb0e2c8dec98efc0760be68753c124/gwt-user-2.4.0.jar(com/google/gwt/dom/client/CanvasElement.java):18: error: cannot access Context
import com.google.gwt.canvas.dom.client.Context;
All the errors thrown are found in gwt-user-2.4.0.jar. Basically, what (I think) it's trying to do is compile the .java source files the jar file contains, which it shouldn't do. Is there a way to make the javadoc command ignore java source files?
I've tried removing the source files from the jar manually, this way the build succeeds. However, since the jar is a gradle dependency, manually altering the file is not an option.
I finally got it to work. As it turned out, the javadoc command needed a sourcepath flag set, because otherwise it would start looking for the source files in the classpath, which contained some source files from the GWT jar file. Since the MinimalJavaDocOptions GWT class doesn't support this, I had to set it manually by adding the following line:
options.addStringOption("sourcepath", <path_to_source>)
This fixed the problem. Obviously it is not ideal, a topic in the Gradle Support Forums has already been created, see http://forums.gradle.org/gradle/topics/allow_javadoc_sourcepath_to_be_set_directly
