在 Eclipse Juno 中运行 Groovy 时出现异常 java.lang.IncompatibleClassChangeError [英] Exception java.lang.IncompatibleClassChangeError while running Groovy in Eclipse Juno

问题描述

我最近下载了 Eclipse Juno 并安装了最新的 Groovy 插件.

I have recently downloaded Eclipse Juno and installed latest Groovy plugin.

现在这是我的 Groovy 文件的样子.

Now here is how my Groovy file looks like.

package groovy_support

class TimePass {
static void main(def args){
    println "Hello World"
}
}

当我从以前的 Eclipse 版本 (indigo) 或命令行运行它时，它会运行.但是，在 Eclipse Juno 上，它在 Eclipse 控制台上抱怨以下异常.

When i run this from either my previous eclipse version (indigo) or from command line, it runs. On Eclipse Juno, however, it complains with following exception on Eclipse console.

Caught: java.lang.IncompatibleClassChangeError: Found class org.objectweb.asm.ClassVisitor, but interface was expected
java.lang.IncompatibleClassChangeError: Found class org.objectweb.asm.ClassVisitor, but interface was expected

请注意，Groovy 库"已经在类路径上.

Note that "Groovy Libraries" are already on classpath.

现在我在这里做错了什么?

Now what am i doing wrong here?

推荐答案

您是否在使用最新的 groovy/依赖 jars?.

Are you on the latest groovy/dependent jars? .

java.lang.IncompatibleClassChangeError 由于向后兼容性问题而发生.客户端代码需要重新编译才能解决.

The java.lang.IncompatibleClassChangeError happens due to back ward compatibility issues. The client code needs to be recompiled to resolve it.

您看到的具体错误是因为 org.objectweb.asm.ClassVisitor 是一个 接口 asm 3.2 和 Class 在 asm 4.0 以后.

The specific error you are seeing is because org.objectweb.asm.ClassVisitor is an Interface in asm 3.2 and a Class in asm 4.0 onwards.
