Class-Path ignored when running jar

Question

My MANIFEST.MF in my application jar contains the following line:

Class-Path: other.jar

My directoy contains the followign files at the same level:

- myApp.jar
- other.jar

I run my application using

java -jar myApp.jar

and get a NoClassDefFoundError for a class which is in other.jar

What am i missing please?

did you try this post --> https://stackoverflow.com/questions/18413014/run-a-jar-file-from-the-command-line-and-specify-classpath — Lahiru Jayathilake, Oct 01 '19 at 06:47
I am not specifying jar and cp as cmd line arguments. If anything i am using the answer in that post. my jar which is declard in my manifest.mf is ignored. — mangusbrother, Oct 01 '19 at 06:49
still get the same error with an absolute path (and can't use absolute path either way as a final solution as this needs to work on several environments) — mangusbrother, Oct 01 '19 at 06:57

Turns out the issue was outside of the manifest file. I had an autogenerated index.list file next to it which blocks classpath from being read.

Index.list should only be an issue if it was *inside* myApp.jar and *wrong*. – Joachim Sauer Oct 01 '19 at 12:49
it is autogenerated using maven assembly plugin so it is always there and won't fit my needs. – mangusbrother Oct 02 '19 at 09:47

Is your Class-Path the last line in the Manifest file?Then it should have an extra line at the end. It may not read the class-path if there is no carriage return in the end.
