Jenkins Groovy管道-需要从执行jar文件中发出命令

Question

我正在使用Jenkins
v：1.647和Pipeline插件v：1.14。我的管道作业提取了运行我的业务流程的常规脚本。我的问题是我有一个可执行jar，它将执行一些Scalr
API操作并返回新的服务器主机名，该主机名是标准输出。我有一个在Jenkins之外工作的片段。

def serverHostName = "java -jar scalr-api.jar testing654 n1-standard-8".execute().text

这段代码在Jenkins之外还可以正常工作，但是我的问题是在运行管道时，我收到了令人讨厌的RejectedAccessException。但是与其他脚本安全性例外不同，我没有办法批准有问题的方法。

我正在寻找可以超越脚本安全性的任何解决方案，并允许我运行该jar并获取标准以供以后在脚本中使用

谢谢

您可以使用sh步骤从管道脚本执行Shell命令。技巧是将已执行命令的输出重定向到文件，然后readFile在下一步中使用读取它。

这应该在linux slave上完成您想要的操作：

sh "java -jar scalr-api.jar testing654 n1-standard-8 > scalr.out"
def out = readFile 'scalr.out'

在Windows从站上：

bat "java -jar scalr-api.jar testing654 n1-standard-8 > scalr.out"
def out = readFile 'scalr.out'
