Nexus无法启动，报如下错误：wrapper  | The nexus service was launched, but failed to start.
经过网上查找资料，得到如下解释：
Java 6 Support EOL
Oracle's support for Java 6 ended in February 2013.  Consequentially as of version 2.6 Nexus now requires a Java 7 JRE to run.
通过修改\nexus-2.6.2-01-bundle\nexus-2.6.2-01\bin\jsw\conf\wrapper.conf文件中的
wrapper.java.command=wrapper.java.command=E:\Java\jdk1.7.0_21\bin\java.exe
问题解决!!
