我正在尝试使用 ant 脚本运行 JMcokit 测试。但我遇到了例外。如其他帖子中所述，我尝试使用'jvmargs'包含java代理，还尝试在类路径中的junit jar之前添加jmockit jar，但它没有用。如果我在我的 Eclipse 中添加 java 代理参数，那么我可以通过 Eclipse 运行它们，但不能通过 ant 脚本。我能够通过 ant 脚本运行它们的唯一方法是在我的 java 路径中添加 attach.dll。但这不是一个可行的解决方案，需要解决。

蚂蚁脚本：

    <!-- Run the TestSuite -->
            <junit fork="yes" description="Runs the Junit testcase." printsummary="yes"
                haltonfailure="${halt.on.junit.failure}" showoutput="yes">

                 <sysproperty key="java.library.path" path="C:/Program Files/Java/jdk1.6.0_12/jre/bin/attach.dll"/>  

                <jvmarg value="-javaagent:${lib.dir}/jmockit.jar" />

                <jvmarg value=" -Dcom.sun.management.jmxremote"/>


            <!--    <classpath path="${lib.dir}/jmockit-0.999.8.jar" />
                <classpath path="${lib.dir}/junit-4.7.jar" />-->


                <classpath>
                    <pathelement location="${lib.dir}/jmockit-0.999.8.jar" />
                    <pathelement location="${lib.dir}/junit-4.7.jar" />
                    <pathelement location="${lib.dir}/activemq-all-5.5.1.jar" />
                    <pathelement location="${classes.dir}" />
                    <!--<fileset dir="${lib.dir}">
                        <include name="**/*.jar" />
                        <exclude name="**/jmockit-0.999.8.jar, **/junit-4.7.jar" />
                    </fileset>-->
                </classpath>


                <!-- <test name="com.quest.shareplex.hadoopconnector.junits.AllTests" 
                    fork="no" todir="${junit.output.dir}"> <formatter type="xml" /> </test> -->

                <batchtest fork="no" todir="${junit.output.dir}">
                    <formatter type="xml" />
                    <fileset dir="${connector.src}">
                        <include name="**/*Test.java" />
                        <exclude name="**/*HDFSUtilsTest*.java" />
                    </fileset>
                </batchtest>

            </junit>

请让我知道，如果有任何其他方法可以工作，或者我做错了什么。我已经尝试了堆栈溢出中提到的所有方法：-尝试更改 java lib 路径-尝试更改 java 类路径-添加 java 代理但没有任何效果。

如果您在 Mac 上，这是因为分叉的 JVM 在类路径中没有 tools.jar。我今天遇到了这个并写了博客。

看起来你的java是普通的jre。

java.library.path java.lang.IllegalStateException：无法加载 Java 代理；请将您的 JDK 中的 lib/tools.jar 添加到 mockit.internal.startup.JDK6AgentLoader.loadAgent(JDK6AgentLoader.java:54 的 mockit.internal.startup.JDK6AgentLoader.getVirtualMachineImplementationFromEmbeddedOnes(JDK6AgentLoader.java:82) 的类路径中

Jmockit 需要JDK才能工作。
