Package org.immutables.processor

Class ProxyProcessor

java.lang.Object

org.immutables.processor.ProxyProcessor

All Implemented Interfaces:

Processor

@Service
public final class ProxyProcessor
extends Object
implements Processor

Proxy processor to overcome eclipse class loading problems which renders our workarounds for Eclipse bugs and quirks useless. When the condition is not detected we try to use direct delegation to org.immutables.value.processor.Processor.

createDefaultDelegate

private static Processor createDefaultDelegate()

createClassLoaderDelegate

private static Processor createClassLoaderDelegate()

We find the delegating classloader by traversing the call stack and looking for the first class that has a classloader from the Eclipse namespace. This is bound to be the bundle classloader of a JDT bundle which can load the required Eclipse compiler types. NOTE: We cannot simply use the thread context class loader. This works in the Eclipse IDE (where it is set to ContextFinder), but not in the JDT Language Server.
