当我运行罐子时,我得到:
And when I run the jar I get:
Exception in thread "main" java.lang.NoClassDefFoundError: com/mxgraph/swing/mxGraphComponent
是jgraphx

推荐答案
是的,这是您不应该滥用system
范围依赖项的原因之一(这在全球范围内是一种不好的做法),并且此问题已经存在在SO上多次提及(此处,此处).我在
Yes, and this is one of the reasons you shouldn't abuse system
scope dependencies (which is globally a bad practice) and this problem has already been mentioned several times here on SO (here, here). I'm proposing a solution to deal with project relative dependencies in a "clean" way in this answer.
