Hello! 

Sorry to bother, but I'm having a problem running pitest through the command line.

This is the command I'm using (Win 10):

java -cp bin;tests\randoop\bin;jars\pitest-1.2.0.jar;jars\pitest-command-line-1.2.0.jar;jars\junit-4.12.jar org.pitest.mutationtest.commandline.MutationCoverageReport --reportDir reports\randoop --targetClasses collections.comparators.FixedOrderComparator --targetTests collections.comparators.FixedOrderComparator_Test --sourceDirs src,tests\randoop\src\

And this is the result:

Exception in thread "main" java.lang.NoClassDefFoundError: org/pitest/mutationtest/config/PluginServices

        at org.pitest.mutationtest.commandline.MutationCoverageReport.main(MutationCoverageReport.java:35)

Caused by: java.lang.ClassNotFoundException: org.pitest.mutationtest.config.PluginServices

        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:357)

        ... 1 more

I've also tried being more specific, but to no avail:

java -cp bin;tests\randoop\bin;jars\pitest-1.2.0.jar;jars\pitest-command-line-1.2.0.jar;jars\junit-4.12.jar org.pitest.mutationtest.commandline.MutationCoverageReport --reportDir reports\randoop --targetClasses collections.comparators.FixedOrderComparator --targetTests collections.comparators.FixedOrderComparator_Test --sourceDirs src,tests\randoop\src\

I get that it is missing a class, but I don't know which, as I believe the classpath is set correctly, mainly because I'm able to run junit using it.

For example, this works:

java -cp bin;tests\randoop\bin;jars\*  org.junit.runner.JUnitCore collections.comparators.FixedOrderComparator_Test

JUnit version 4.12

OK (398 tests)

Thanks for your help!

Finally figured it out after reading how pitest-commandline is compiled.

In order to run pitest-commandline, you have to have the following jars:

pitest-(version_number).jar

pitest-command-line--(version_number).jar

pitest-entry-(version_number).jar

I found that you need pitest-entry after reading the POM.xml of pitest-command-line.

Please add this explicitly to the FAQ as it is not obvious.
