修改

我正在尝试在当前构建目录中构建一个文件。采用构建环境变量，我创建了一个字符串，并尝试使用它创建一个新文件。但是，当我这样做时，我得到错误“没有这样的属性”

String jobDir = "C:\\Program Files (x86)\\Jenkins\\jobs\\${env.JOB_NAME}\\builds\\${env.BUILD_NUMBER}\\"
String FILEDIR = jobDir+"SOTR.log"
@Field File outFile = new File(FILEDIR)

我收到此错误：

发生此错误是因为您已使用变量@Field的{{1}}注释 - 当您这样做时，它会将此变量从本地范围移动到脚本类范围。并且因为您引用了本地范围变量outFile，所以它会抛出FILEDIR，因为类级别没有这样的字段。如果您打算这样做，请删除groovy.lang.MissingPropertyException注释或将其添加到所有其他变量。

您也可以将@Field变量构建为：

jobDir

另请注意，默认情况下，Jenkins不允许使用String jobDir = "${env.JENKINS_HOME}\\jobs\\${env.JOB_NAME}\\builds\\${env.BUILD_NUMBER}"类，如果您不允许服务器这样做，您将获得如下异常：

java.io.File

Groovy使用当前构建路径创建文件？
