【java.lang.UnsupportedClassVersionError】版本不一致出錯

標籤：

今天運行appium的一個指令碼，遇到了這個問題：

   

java.lang.UnsupportedClassVersionError: io/appium/java_client/AppiumDriver : Unsupported major.minor version 51.0    at java.lang.ClassLoader.defineClass1(Native Method)    at java.lang.ClassLoader.defineClass(Unknown Source)    at java.security.SecureClassLoader.defineClass(Unknown Source)    at java.net.URLClassLoader.defineClass(Unknown Source)    at java.net.URLClassLoader.access$000(Unknown Source)    at java.net.URLClassLoader$1.run(Unknown Source)    at java.security.AccessController.doPrivileged(Native Method)    at java.net.URLClassLoader.findClass(Unknown Source)    at java.lang.ClassLoader.loadClass(Unknown Source)    at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)    at java.lang.ClassLoader.loadClass(Unknown Source)    at java.lang.ClassLoader.loadClassInternal(Unknown Source)    at java.lang.Class.getDeclaredMethods0(Native Method)    at java.lang.Class.privateGetDeclaredMethods(Unknown Source)    at java.lang.Class.getMethod0(Unknown Source)    at java.lang.Class.getMethod(Unknown Source)    at org.junit.internal.builders.SuiteMethodBuilder.hasSuiteMethod(SuiteMethodBuilder.java:18)    at org.junit.internal.builders.SuiteMethodBuilder.runnerForClass(SuiteMethodBuilder.java:10)    at org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:59)    at org.junit.internal.builders.AllDefaultPossibilitiesBuilder.runnerForClass(AllDefaultPossibilitiesBuilder.java:26)    at org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:59)    at org.junit.internal.requests.ClassRequest.getRunner(ClassRequest.java:26)    at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.<init>(JUnit4TestReference.java:32)    at org.eclipse.jdt.internal.junit4.runner.JUnit4TestClassReference.<init>(JUnit4TestClassReference.java:25)    at org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader.createTest(JUnit4TestLoader.java:41)    at org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader.loadTests(JUnit4TestLoader.java:31)    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:452)    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683)    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390)    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)

問題解析：

   我的eclipce的jdk的版本是1.6，我用的java_client是2.1的

   查看java_client的運行需要的jdk版本是1.7：

降低java-client的版本降至1.1.0

所以問題就解決啦。。。。。
