07/07/2016, 1:21 PMjava -jar dokka-fatjar.jar src -java requires the class com.sun.javadoc.DocErrorReporter (and maybe others).
The fix, include tools.jar on the classpath, which makes the correct command:
java -cp $JAVA_HOME/lib/tools.jar:dokka-fatjar.jar org.jetbrains.dokka.MainKt src -java
This should probably be documented in the README.
This relates to #58, which you might wish to revisit that one as well, because on my machine (OS X El Capitan with jdk 1.8.0_92 (also confirmed on 1.8.0_51 -- I'm suspecting jdk 8 in general)), classes.jar doesn't exist, and tools.jar is not $JAVA_HOME/../lib/tools.jar but $JAVA_HOME/lib/tools.jar (with JAVA_HOME = /usr/libexec/java_home).
