Dependent class can't be found when invoke by java -classpath xxx -jar jarfile, but can be found by java -classpath xx class

Question

Case 1:

java  -cp LRS3rdPartyClient.jar -jar tasks.jar 

Case 2:

java -classpath LRS3rdPartyClient.jar;tasks.jar com.lombardrisk.build.WaitForServerStart

Case 1 does not execute, because a class, which resides in LRS3rdPartyClient.jar cannot be found, whereas the Case 2 executes properly.

I'am quite confused.

Answer 1

When using -jar, the classpath is ignored. Only the classpath specified in the jar file's manifest is used.
