Interactively exporting an OT plug-in using the wizard may fail with errors like: "The type org.objectteams.IBaseMigratable cannot be resolved. It is indirectly referenced from required .class files" This indicates that the scripted compile doesn't find the OTRE. This can be worked around by importing the org.eclipse.objectteams.runtime plug-in into the workspace, e.g.: Import ... > Plug-in Development > Plug-ins and Fragments (x) Import from the active target platform ... (x) Select from all ... (x) Binary projects -> org.eclipse.objectteams.runtime > Finish Need to check how pde-build resolves the OTRE, perhaps it has difficulties with the nested jar?
Another - simpler - workaround is checking the following option within the export wizard: Options > [x] Use class files compiled in the workspace.
Here are some potentially related bugs: Bug 103136 - PDE seems to be unable to handle so-called jar'ed library plugins deployed in target platform. Bug 147831 - [compiler] failed to find classes wrapped in a bundle Bug 157375 - PDE should support building against nested JARs The OTDT expands the OTRE classpath container to s.t. like configuration/org.eclipse.osgi/bundles/427/1/.cp/lib/otre.jar (see org.eclipse.objectteams.otdt.core.ext.OTREContainer) Somehow, this expansion seems not to be used for ant-based compilation. I'm not sure at this moment how importing the binary runtime makes a differences.
Stephan, thanks for opening the issue. I've used the second workaround (classes compiled in the workspace).
Problem has been resolved by a change in how the OTRE is built and packaged: Instead of building three jars outside the automated build (otre.jar, otre_min.jar, otre_agent.jar), the source have been migrated into the org.eclipse.objectteams.runtime plugin, and thus the OTRE is by default a plugin now (i.e., no more otre.jar only the plugin jar exists). The main benefit lies in the fact that we're no longer using nested jars, which fixes this bug. Additionally, all three jars are now created via PDE/Build (with customBuildCallbacks for jar-ing otre_min.jar and otre_agent.jar). This change is implemented between r587 and r636: + move sources from OTRE to org.eclipse.objectteams.runtime + adjust the plugin configuration and build scripts + update implementation of classpath container "OTRE" - discard useless variable "OTRUNTIME_LIBDIR" - add logic to check existence of "bin/" folder in runtime plugin, if found use this for "OTRE" otherwise the resolved plugin itself. Note, that when releasing this change, documentation for running OT/J programs outside Eclipse needs updating, too, to refer to the plugin instead of otre.jar.
