Incompatible code can be used/generated when using JDK8 on the command line and JDK11 in Eclipse (or vice versa).
The explanation for this is given in https://github.com/apache/felix/pull/114 :
Java 9 introduces overridden methods with covariant return types for the following methods in java.nio.ByteBuffer:
* position(int newPosition)
* limit(int newLimit)
* flip()
* clear()
* mark()
* reset()
* rewind()
In Java 9 they all now return ByteBuffer, whereas the methods they override return Buffer,
resulting in exceptions like this when executing on Java 8 and lower:
java.lang.NoSuchMethodError: java.nio.ByteBuffer.limit(I)Ljava/nio/ByteBuffer
This is because the generated byte code includes the static return type of the method, which is not found on Java 8 and lower because the overloaded methods with covariant return types don't exist (the issue appears even with source and target 8 or lower in compilation parameters).
The solution is to cast ByteBuffer instances to Buffer before calling the method.

As long as we depend on the internal Gson packages, we need to use the
Gson bundle provided by Eclipse Orbit instead of the official one.

For the runtime dependencies a template from the EnRoute project has
been used. To allow further customization and usages of different Maven
scopes, we migrate the template to this repo.

This commit move the files to the correct directories and prepare the
whole infrastructure. After that hopefully small changes needs to be
done only to get tests running.
Some tests has been already enabled, too.
