我创建了一个14class的java项目。到目前为止,我一直在使用default-package。 今天我用我的所有类移动了:Refactor - Move,我创建了一个新的包。

这样做之后,我无法访问我的资源。运行我的MainForm类我收到此错误:

java.lang.NullPointerException

        at com.anreas.mls.MainForm.<init>(MainForm.java:279)

编辑:MainForm第279行:

        btnHelp.setIcon(new ImageIcon(MainForm.class.getResource("images/help.png")));
