我的Jenkinsfile中有这个：

tools {
    hudson.plugins.doxygen.DoxygenInstallation "doxygen-1.8.16"
}

这将导致此错误：

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 7: unexpected token: doxygen-1.8.16 @ line 7,column 52.
   s.doxygen.DoxygenInstallation "doxygen-1
                                 ^

1 error

我在Jenkins的全局工具配置中将doxygen-1.8.16添加为Doxygen安装。

在Jenkinsfile中将Doxygen作为工具添加的正确方法是什么？
