Question

我遇到了GroovyScriptEngine的问题-似乎无法使用内部类。有人知道GroovyScriptEngine还是有一些限制？

我有一个包含这两个文件的目录：

// MyClass.groovy

public class MyClass {
    MyOuter m1;
    MyOuter.MyInner m2;
}

和

// MyOuter.groovy

public class MyOuter {
    public static class MyInner {}
}

我有以下测试课程：

import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;

import groovy.util.GroovyScriptEngine;

public class TestGroovyScriptEngine {

    public static void main(String[] args) throws MalformedURLException, ClassNotFoundException {

        final File myGroovySourceDir = new File("C:/MyGroovySourceDir");

        final URL[] urls = { myGroovySourceDir.toURL() };
        GroovyScriptEngine groovyScriptEngine = new GroovyScriptEngine(urls,
                Thread.currentThread().getContextClassLoader());

        Class<?> clazz = groovyScriptEngine.getGroovyClassLoader().loadClass("MyClass");
    }

}

运行它时，出现以下编译错误：

Exception in thread "main" org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
C:\MyGroovySourceDir\MyClass.groovy: 3: unable to resolve class MyOuter.MyInner 
 @ line 3, column 2.
    MyOuter.MyInner m2;
    ^

我本来希望“干净的编译”，但是内部类似乎引起了问题。

我的groovy类可以在groovyc或Eclipse中在命令行上很好地编译。

加载使用其他类的静态内部类的类时，GroovyScriptEngine抛出MultipleCompilationErrorsException
