从 Groovy 2.3.0 开始，@SourceURI 注释可用于使用脚本位置的 URI 填充变量.然后可以使用此 URI 获取脚本的路径:

As of Groovy 2.3.0 the @SourceURI annotation can be used to populate a variable with the URI of the script's location. This URI can then be used to get the path to the script:

import groovy.transform.SourceURI
import java.nio.file.Path
import java.nio.file.Paths

@SourceURI
URI sourceUri

Path scriptLocation = Paths.get(sourceUri)

请注意，这仅在 URI 是 file: URI(或安装了 FileSystemProvider)，否则为 FileSystemNotFoundException 将由Paths.get(URI) 调用.特别是，某些 Groovy 运行时(例如 groovyshell 和 nextflow)会返回 data: URI，该 URI 通常与已安装的 FileSystemProvider 不匹配.

Note that this will only work if the URI is a file: URI (or another URI scheme type with an installed FileSystemProvider), otherwise a FileSystemNotFoundException will be thrown by the Paths.get(URI) call. In particular, certain Groovy runtimes such as groovyshell and nextflow return a data: URI, which will not typically match an installed FileSystemProvider.
