Thank you very much, this helps me, and I simply make a summary and hope to help others.
If anybody wants to get the line coverage, the class files must contain line number attributes. For my use scenario, without line number attributes lead that iCoverageNode.getLineCounter().getCoveredCount() always return 0. How to check if class files contain the line number attributes please refer to https://groups.google.com/d/msg/jacoco/d-30r6hVrV4/d_3Dk3GdCgAJ. If you just want to get coverage of other metrics, it will not be affected by the missing line number. 在 2019年1月6日星期日 UTC+8上午10:01:48，Evgeny Mandrikov写道： > > > > On Saturday, January 5, 2019 at 4:29:03 PM UTC+1, Tool Ply wrote: >> >> According to >> https://groups.google.com/d/msg/jacoco/d-30r6hVrV4/d_3Dk3GdCgAJ, this >> was indeed because of that the decompiled classes has no LineNumberTable. >> >> So, while the document says " To calculate line coverage class files >> must contain line number attributes.
