Nexus启动报错: Unsupported major.minor version 51.0

1.遇到问题

   今天搭建Nexus私服,出现了以前没遇到过的错误。

    a).采用console-nexus.bat开启报错:

wrapper| --> Wrapper Started as Consolewrapper| Launching a JVM...jvm 1| java.lang.UnsupportedClassVersionError: org/sonatype/nexus/bootstrap/jsw/JswLauncher : Unsupported major.minor version 51.0jvm 1|at java.lang.ClassLoader.defineClass1(Native Method)jvm 1|at java.lang.ClassLoader.defineClassCond(ClassLoader.java:631)jvm 1|at java.lang.ClassLoader.defineClass(ClassLoader.java:615)jvm 1|at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141)jvm 1|at java.net.URLClassLoader.defineClass(URLClassLoader.java:283)jvm 1|at java.net.URLClassLoader.access$000(URLClassLoader.java:58)jvm 1|at java.net.URLClassLoader$1.run(URLClassLoader.java:197)jvm 1|at java.security.AccessController.doPrivileged(Native Method)jvm 1|at java.net.URLClassLoader.findClass(URLClassLoader.java:190)jvm 1|at java.lang.ClassLoader.loadClass(ClassLoader.java:306)jvm 1|at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)jvm 1|at java.lang.ClassLoader.loadClass(ClassLoader.java:247)jvm 1| Could not find the main class: org.sonatype.nexus.bootstrap.jsw.JswLauncher.Program will exit.jvm 1| Exception in thread "main"wrapper| JVM exited while loading the application.wrapper| Reloading Wrapper configuration...wrapper| Launching a JVM...

    b).采用install-nexus.bat、start-nexus.bat开启报错:

wrapper| Starting the nexus service...wrapper| Waiting to start...wrapper| Waiting to start...wrapper| Waiting to start...wrapper| The nexus service was launched, but failed to start.

2.分析问题

   看日志的问题,大概就是版本存在问题,找不到Java虚拟机。

   Java版本:1.6.0_45

   Nexus版本: 2.7.2-03

   按照网上的办法是修改bin/jsw/conf/wrapper.conf中的wrapper.java.command

wrapper.java.command=C:/Lynch/Develop/Java/jdk1.6/bin/java.exe

   指向自己的jdk,似乎在特俗的Nexus版本可以解决,这里我还是不行。

3.解决问题

   最终查询文档得到思路

Sonatype Nexus 2.6.0Java 6 Support EOLOracle's support for Java 6 ended in February 2013.Consequentially as of version 2.6 Nexus now requires a Java 7 JRE to run.
Sonatype Nexus OSS 2.5.0Java 6 Support is DeprecatedJava 6 reached Official EOL on February 2013.Since it is no longer receiving updates we are deprecating support for running Nexus with Java 6 in the 2.5 release, and will be removing it in the upcoming 2.6 release.
Sonatype Nexus 2.0 Release NotesJDK 7 SupportNexus 2.0 is the first version of Nexus verified to work with Java 7. The recommended versions areOracle 7u2 or later *IBM Java 7.0 GA or later* Note: Nexus 2.0 will not run on versions of Oracle Java 7 prior to 7u2.When running with Java 6 the recommended versions are:Oracle Java 6u30 or laterIBM Java 6.0.10.0 or Later

   a).Nexus的2.6版本及其以后版本

       使用的Java的jdk7.

   b).Nexus的2.0-2.5版本

       使用Java的jdk6的update30版本及其以后的jdk6版本

       使用Java的jdk7的update2版本及其以后jdk7版本

   c).最终解决方案

       升级jdk7(注意jdk的update版本,升级最新版本就可以)
