Java 带有自定义类加载器的Jmockit：系统类加载器不支持在实时阶段将JAR文件添加到系统类路径
我使用的自定义类装入器如下所示：Java 带有自定义类加载器的Jmockit：系统类加载器不支持在实时阶段将JAR文件添加到系统类路径,java,classloader,jmockit,Java,Classloader,Jmockit,我使用的自定义类装入器如下所示： public class MyClassLoader extends URLClassLoader { public MyClassLoader(ClassLoader parent) { super(((URLClassLoader) parent).getURLs(), parent); } } 我也在用jmockit。例如，考虑这个代码： public static void main(String[] args) thr
public class MyClassLoader extends URLClassLoader {
public MyClassLoader(ClassLoader parent) {
super(((URLClassLoader) parent).getURLs(), parent);
}
}
public static void main(String[] args) throws Exception {
new MockUp<Main>(){
};
}
publicstaticvoidmain（字符串[]args）引发异常{
新模型（）{
};
}

System class loader does not support adding JAR file to system class path during the live phase!
Unable to add C:\Users\hmdha\.m2\repository\org\jmockit\jmockit\1.23\jmockit-1.23.jar to system class path - not supported by system class loader or configuration error!
我是否应该向类加载器添加任何内容来防止此错误？在junit/nunit jar之前的类路径上是否有jmockit？如果没有，你通常会有问题。或者，您可以将此注释添加到测试类：
@RunWith（JMockit.class）您可能还需要查看，并确保您的设置与说明一致 在junit/nunit jar之前，类路径上有jmockit吗？如果没有，你通常会有问题。或者，您可以将此注释添加到测试类：
@RunWith（JMockit.class）
