jenkins - Groovy 使用当前构建路径创建文件？

Question

编辑

我正在尝试在当前构建目录中构建一个文件。利用构建环境变量，我创建了一个字符串并尝试用它创建一个新文件。但是，当我这样做时，我收到错误“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:

groovy.lang.GroovyRuntimeException: Failed to create Script instance for class: class WorkflowScript. Reason: groovy.lang.MissingPropertyException: No such property: FILEDIR for class: WorkflowScript

发生此错误的原因是您对变量 outFile 使用了 @Field 注释 - 当您这样做时，会将此变量从本地范围移动到脚本类范围。并且因为您引用本地范围变量 FILEDIR ，所以它会抛出 groovy.lang.MissingPropertyException ，因为在类级别没有这样的字段。删除 @Field 注释或将其添加到所有其他变量(如果这是您的意图)。

您还可以将 jobDir 变量构建为:

String jobDir = "${env.JENKINS_HOME}\\jobs\\${env.JOB_NAME}\\builds\\${env.BUILD_NUMBER}"

另请记住，默认情况下 Jenkins 不允许使用 java.io.File 类，如果您不允许服务器这样做，您将收到如下异常:

org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: Scripts not permitted to use new java.io.File java.lang.String
