This beta release of the plugin includes the recent Checkstyle 5.0beta1 (read here).
The 5.0.0 version of the plugin will be a major restructuring of the existing code. This includes splitting the
grown, rather monolithic plugin into multiple smaller plugins where future development will be much easier to
handle (hopefully).
Most of the dissecting and putting-back-together has already taken place but is not yet
finished.
However, on the surface most things will still be where you have come to know them.
After you install the plugin and restart Eclipse the plugin will automatically migrate your Checkstyle-enabled
projects to the new plugin version. The .project
file of those projects will be modified in this
process to reflect changes in the plugins package structure.
