无法获得产品版本。如何使用ansible

Question

设置CLASSPATH

我可以通过在UNIX中的命令提示符处执行此操作来获取Weblogic版本。

$ . /app/wlserv*/server/bin/setWLSEnv.sh
$ java weblogic.version

我希望在远程主机上使用Ansible来获取Weblogic版本，所以我写了这本剧本：

---
  - hosts: dest_nodes

    tasks:
      - name: Get weblogic version
        shell: "/app/wlserv*/server/bin/setWLSEnv.sh;java weblogic.version"
        register: wlsversion

      - debug:
          msg: "{{ wlsversion }}"

但是，出现此错误：

        "discovered_interpreter_python": "/usr/bin/python"
    },

    "stdout_lines": [

        "",
        "Your environment has been set."
    ]
}

从输出中，我看到确实设置了类路径，但是在远程主机上java weblogic.version命令失败。

您能建议我如何将Weblogic版本注册到wlsversion变量吗？
