JMockit ERROR - Native library for Attach API not available in this JRE

Question

I have looked for answers to this problem and tried the only solution to this I could find (jmockit: Native library for Attach API not available in this JRE error)

I tried adding attach.dll to PATH environment variable with no success. (C:\Program Files\Java\jdk1.7.0_60\jre\bin\attach.dll)

any other suggestions?

You are using jre instead of jdk. Go to Windows->Preferences->Java->Installed JRE's and remove jre and add jdk, also select it as default.
