NullPointerException about meghanada-server HOT 7 CLOSED

I tried build jar, but couldn't reproduce it.
Please check your MANIFEST.MF.

from meghanada-server.

@mopemope Hm I don't see any MANIFEST.MF in my local directory, only Manifest.param file. Can you tell me where should I look for it please?

from meghanada-server.

Please try again shadowJar

./gradlew clean shadowJar

And check following file.

./build/tmp/shadowJar/MANIFEST.MF

from meghanada-server.

@mopemope Ok, I recompiled and here's MANIFEST.MF file:

sandric@sandric-mac ~/meghanada-server> cat build/tmp/shadowJar/MANIFEST.MF
Manifest-Version: 1.0
Date: 2016-09-08T16:44:47+0300
Version: 0.1.0-620444b
Main-Class: meghanada.Main

from meghanada-server.

@mopemope Hi , I have the same issue.
I'm running on linux archlinux.
My manifest looks fine

Manifest-Version: 1.0
Date: 2016-09-09T09:58:49+0900
Version: 0.1.0-f5d3113
Main-Class: meghanada.Main

My java version

java -version 
openjdk version "1.8.0_102"
OpenJDK Runtime Environment (build 1.8.0_102-b14)
OpenJDK 64-Bit Server VM (build 25.102-b14, mixed mode)

The error

java -jar ~/.meghanada/meghanada.jar --help
Exception in thread "main" java.lang.NullPointerException

from meghanada-server.

@ejemba @sandric Hmm. I can't reproduce it ...
Do you use gradle wrapper ?

from meghanada-server.

@mopemope yes I used gradle wrapper.
I identified the problem I think, with our configuration.

https://github.com/mopemope/meghanada-server/blob/master/src/main/java/meghanada/Main.java#L30

return mainAttributes.getValue("Version");

does return null rather what we found in the Manifest.Mf

I was wondering if the correct key to use shouldn't be : Attributes.Name.MANIFEST_VERSION rather than "Version" ?
