Oh well. TL4J is required to build the project - I changed all dependencies to use maven central, but build fails:
[javac] import com.google.common.testing.junit3.TearDownTestCase;
[javac] ^
[javac] C:\Projects\guiceberry-read-only\src\com\google\inject\testing\guiceberry\junit3\GuiceBerryJunit3TestCase.java:19: error: package com.google.common.testing.junit3 does not exist
And from what I read up, it seems that sometime in the future most of the tl4j features will be in Guava, but this library is missing.
If you don't care about the older junit tests, the build compiles fine, but I don't know if you can afford to remove the junit3 tests.
