无法获取产品版本.如何使用 ansible 设置 CLASSPATH

Question

我可以通过在 unix 的命令提示符下执行此操作来获取 weblogic 版本。

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

我希望在远程主机上使用 ansible 获取 weblogic 版本，所以我写了这个剧本：

---
- 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，我收到此错误：

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

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

您能否建议如何将Weblogic版本注册到wlsversion变量？
