No such File exception in Jenkins, but runs fine locally

Question

I have a JUnit test file for my code that reads an xml file and converts it to string:

String xml = new String(Files.readAllBytes(Paths.get("src\\test\\resources\\testfile.xml")));

The test runs and passes locally, but when I run a Jenkins build, it fails with java.nio.file.NoSuchFileException: src\\test\\resources\\testfile.xml

Do I need to change my file path when pushing?

Answer 1

you should use resource as stream for this:

InputStream is = getClass().getClassLoader().getResourceAsStream(fileName);
if (is != null) {
    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
    String xml = reader.lines().collect(Collectors.joining(System.lineSeparator()));
}

(code can be improved a lot ... but it will give you a direction)

(check out try by resource to handle streams)

Answer 2

Alright, so I figured out my problem and I feel pretty silly. When Java builds on my windows machine, using \\ to seperate files is fine; however when Jenkins builds, files need to be seperated with /

ie my file names should be

src/test/resources/testfile.xml
