title: java.io.FileNotFoundException in jenkins workspace
body: <p>I have a problem with a file in my jenkins workspace, I need to read a <code>diffFile.txt</code>, I'm using the global variable <code>WORKSPACE</code> like this <code>File fileDiff = new File(env.WORKSPACE+&quot;/diffFile.txt&quot;)</code> but i get this error. I've checked and the file is there, I can read it with <code>cat</code>, but not with <code>File</code>, do you know what I can do to fix that?</p>
