I have the following code to check the last modification on a file saved on network drive.

private long determineLastEdit(ILoaderData file) {

    String localDir = "c:\\Software\\log\\"; 
    String localPDF = "empty28.pdf";
    String originDir = "smb:\\ProdName\\ShareName\\Temp\\username\\path\\to\\folder\\";
      //My company remote storage

    File localFile = new File(originDir + localPDF)
      //this does not work

    //File localFile = new File(localDir + localPDF)
      //this works as expected

    Date currentTime = new Date();
    long timeCurrent = currentTime.getTime();
    long timeFile = localFile.lastModified();
      //this returns 0 on remote, correct time …

我正在实现声明式 Jenkinsfile，我想运行 Windows 命令并将结果分配给变量。

这是我的代码：

stage('check latest commit') {
    steps {
        script{
            COMMIT = bat("c:\\Software\\Git\\bin\\git.exe log -n 1 --pretty=format:'%%H'").trim() as String
            echo "${COMMIT}"
        }
    }
}

我在 Jenkins 作业中收到以下日志

c:\Software\JenkinsWorkspace\workspace\TFS - XXX>c:\Software\Git\bin\git.exe log -n 1 --pretty=format:'%H' 
'656669102c187fe390a1e9d72ed47aa2d8528ad6'[Pipeline] }
[Pipeline] // script

因此该命令按预期执行并返回 HEAD 中最新提交的哈希值。伟大的。然而：

[Pipeline] End of Pipeline
java.lang.NullPointerException: Cannot invoke method trim() on null object
    at org.codehaus.groovy.runtime.NullObject.invokeMethod(NullObject.java:91)
    at org.codehaus.groovy.runtime.callsite.PogoMetaClassSite.call(PogoMetaClassSite.java:48)

在运行结束时，我收到此错误。这意味着命令的结果值为null，即使命令本身产生结果。

如果我不包括修剪，例如：

stage('check latest commit') {
    steps {
        script{
            COMMIT = bat("c:\\Software\\Git\\bin\\git.exe log -n 1 --pretty=format:'%%H'")
            echo "${COMMIT}" …
