Java – error: unable to initialize module treewalker – unable to instantiate junittestcase
After importing Maven project into eclipse Luna, the following error will pop up when saving after modifying the method:
Junittestcase refers to a module in the checkstyle XML file:
<module name="JUnitTestCase"/>
I have installed "checkstyle configuration plug-in m2eclipse" and "checkstyle plug in 6.4.0" The plugin definition of 'maven checkstyle plugin' in my POM file specifies version 2.10
Note: I realize that this is similar to some other problems, with the same error (but different modules are specified), but I haven't found a satisfactory solution yet I believe I can delete the module entry in the checkstyle configuration file, but I ask it to work according to the design, which is not the best choice
Solution
Junittestcase is removed in checkstyle 6.2 So you should downgrade to checkstyle 6.1 1, or from checkstyle Delete module reference from XML
