【问题描述】：

大家好，我正在尝试将 AIX 服务器从机器连接到 Windows 主从机器。下面是我的配置页面。

在 AIX 服务器上找到的 JRE 版本是这样的（顶部是 java 路径，我没有包含 /bin，因为 Hudson 在尝试运行时会自动添加它们；请参阅下面的日志）：

gbnruad0016:/usr/java5/jre/bin/

java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build pap32devifx-20110627 (SR12     FP5 ))
IBM J9 VM (build 2.3, J2RE 1.5.0 IBM J9 2.3 AIX ppc-32 j9vmap3223ifx-20110624 (JIT  enabled)
J9VM - 20110623_85457_bHdSMr
JIT  - 20100623_16197ifx10_r8
GC   - FP22011_06)
JCL  - 20110627

但是当我想运行从代理时，我得到了这些错误，

不知道1.4.2版本是从哪里来的？我在本地机器上检查了它的 1.6.0，在 AIX 服务器上检查了它的 1.5.0。

也许这就是这个错误的根本原因？

谢谢！

从上面的错误日志中

[10/23/13 04:07:59] [SSH] 检查 /usr/java5/bin/java 的 java 版本 hudson.util.IOException2：在 [java、/usr/bin/java、/usr/java/default/bin/java、/usr/java/latest/bin/java、/usr/ 中找不到任何已知的受支持的 java 版本local/bin /java, /usr/local/java/bin/java, /gcdm/sys/cdms011/hudson/jdk/bin/java, /usr/java5/bin/java]，和我们也未能安装 JDK 作为后备

我的第一个怀疑是您没有安装 java5，或者您没有安装 /usr/java5 的权限。

更新：再次阅读问题并注意到您的 java 路径是 /usr/java5/jre 而不是 /usr/java5。可能会有帮助。
