Helium DevClient giving "inStream" error

Answered

I am getting this error when trying to run the Helium DevClient

java -jar ~/ws/he-dev-client/HeliumDev-app-1.31.1-jar-with-dependencies.jar
Exception in thread "main" java.lang.NullPointerException: inStream parameter is null
	at java.base/java.util.Objects.requireNonNull(Objects.java:247)
	at java.base/java.util.Properties.load(Properties.java:407)
	at com.mezzanine.helium.ea.dev.App.main(App.java:178)

Any ideas as to what might cause this?

This could be caused by several issues with the DevClient itself, although my testing with that version doesn't give any issue so I doubt it's that. It might be the java version you are using that is causing the problem. Helium needs to be run using Java 1.8 and would usually throw the same error if you are using a different version.

Was having the same issue. Using the correct version of Java fixed it. Thanks!

Okay, you could always just alias it with the right version of Java? something like alias he="/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/jre/bin/java -jar ~/bin/HeliumDev-app-1.29.1-jar-with-dependencies.jar"
