Question

我尝试在 Eclipse RCP 应用程序中使用 classmexer，但我只得到一个 IllegalStateException:

在我放置的运行时配置中:

-javaagent:C:/Users/kd/workspace/ClassmexerTester/classmexer.jar

难道我必须在plugin.xml中添加一些东西吗？

Answer 1

in the runtime configuration I put:

-javaagent:C:/Users/kd/workspace/ClassmexerTester/classmexer.jar

这听起来不对。您需要将 -javaagent:C:/Users/kd/workspace/ClassmexerTester/classmexer.jar 作为 JVM 参数传递。您在产品配置的启动选项卡上的 JM 参数 Pane 中指定这些。

您还需要在 plugin.xml 的运行时选项卡的类路径 Pane 中包含的 jar 列表中的 classmexer.jar。
