我一直在尝试使用 Java（runtime().exec() 和 ProcessBuilder）运行 anisble-playbooks，在这两种情况下，我发现我希望使用命令行传递的额外变量永远不会被执行，或者看起来是这样。
ProcessBuilder builder = new ProcessBuilder("ansible-playbook", "/root/playbooks/script-ilo.yml", "-e", "'@/tmp/vars.yml'");
和
String[] ansible_run = {"ansible-playbook", "/root/playbooks/script-ilo.yml", "-e", "'@/tmp/vars.yml'"};
Process p = Runtime.getRuntime().exec(ansible_run,null);
我将代码打包为 jar 并在测试系统中执行，在这两种情况下，ansible 都会运行 playbook 并抛出错误。
# java -jar /home/admin/test-script.jar
