Is "Open Type" feature extensible? [message #639786]

Hey,

We are using eclipse to develop java program for mobile devices. When we debugged on a device, it always happened that the java libs running on the device is not the same version as the ones used in the eclipse project. We do have the right source code for the libs running on the device but do not have the binary class jars. The current "Open Types" feature seems only can search for source files of the classes which are on the classpath. Is it possible to make it also search a specified source jar/folder which does not have corresponding classes in the project's classpath?

Eclipse debug source look up does provide extension points which allow us to add more paths to the search path but the "Open Type" feature does not. So, now when we step into a class, the right source file can be opened but when we want to open a source file and set breakpoints, the "Open Type" feature does not help.

Thanks.

Raymond

As a workaround, you could create a temporary project (like the
"External Plug-in Libraries" created by PDE) and add those classes to
the classpath of the Project.

I'm cc-ing the JDT forum where you may get more helpful answers.

Right, creating a project with those classes is the way to go as 'Open
Type' by definition only finds the types that are on the Java build path
of a project.
