  • switched from and ant to gradle based build system, this is reflected in the directory structure
  • split unit and integration tests
  • added docker support for integration tests
  • now using travis-ci for continous integration
  • now using PMD and codacy for code quality
  • now using codecov for unit and integration test coverage
  • moved examples and tutorial to a separate repository https://github.com/NLeSC/Xenon-examples

What's missing:

The GridFTP adaptor is not considered stable yet. It is not part of this release.

There is no adaptor writing documentation at the moment, nor is the Javadoc complete for the internals methods of the adaptor implementations.

It should be made easier to inspect at runtime which adaptors are available and what properties they support.

We can always use more adaptors, e.g, for SWIFT, HDFS, YARN, Azure-Batch, etc. These are planned for 2.1.0 or later.

We can always use more interfaces, e.g. for clouds (to start and stop VMs). This is planned for 3.0.0.
