我想从 C# 程序集中提取构建版本，作为在 Windows 服务器上运行的 Jenkins 管道的一部分。程序集文件如下所示：
// [...snip...]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("")]
[assembly: AssemblyProduct("BulkUpdater")]
[assembly: AssemblyCopyright("Copyright © 2016")]
// [...snip...]
// [assembly: AssemblyVersion("1.0.*")]
[assembly: AssemblyVersion("3.4.1.9")]
[assembly: AssemblyFileVersion("3.4.1.9")]
我对 Jenkins 相当陌生，但对 Groovy 很熟悉，所以我转向了明显的 Groovy 工具来实现这一点：
String captureVersionFromAssembly(String assemblyFilename) {
String version
File file = new File(assemblyFilename)
file.eachLine { line ->
// avoid commented AssemblyVersion
if (line.contains("AssemblyVersion") && !line.startsWith('//')) {
version = line.split('"')[1]
}
}
version
}
它3.4.1.9在 Jenkins 管道之外正确返回。
我知道 Jenkins 管道插件要求您授予管道脚本使用File该类的权限。我已经在注册它这样做in-process script approval的部分Manage Jenkins。
在 Jenkins 管道中，File该类似乎无法找到文件（即使bat 'dir'显示它们在那里。）
dir('omega-elms') {
bat 'dir'
bat 'dir ELMS_Desktop_Application'
echo "Working directory: ${pwd()}"
fileExists('ELMS_Desktop_Application')
fileExists('ELMS_Desktop_Application\\CARS')
fileExists('ELMS_Desktop_Application\\CARS\\BulkUpdater')
fileExists('ELMS_Desktop_Application\\CARS\\BulkUpdater\\Properties')
}
def fileExists(String filename) {
echo "'$filename' exists? ${new File(filename).exists()}"
}
给出以下日志：

我还预先添加了工作目录以提供绝对文件路径：
String assembly = "${pwd()}\\ELMS_Desktop_Application\\CARS\\BulkUpdater\\Properties\\AssemblyInfo.cs"
但这也不能解决问题。
有什么建议么？
以下是丑陋但有效的：
在appversion.bat中assemblyDir：
@echo off
REM extract version from assembly ignoring commented out version
FOR /F delims^=^"^ tokens^=1^,2^* %%A IN ('findstr /L /B /C:"[assembly: AssemblyVersion" "AssemblyInfo.cs"') DO (
set "version=%%B"
)
echo %version%
在詹金斯管道中：
String versionNumber
dir(assemblyDir) {
bat './appversion.bat >stdout'
versionNumber = readFile('stdout').trim()
}
// ...use versionNumber here
尚不清楚为什么这些File方法在 Jenkins 管道中找不到文件。更好地理解会很有趣。例如，这是故意的安全功能吗？
