Warnings on install and run #2

Closed ViolanteCodes closed 2 years ago

ViolanteCodes commented 2 years ago

Just a few questions re: installation and running -

  1. Why does the installation line in the readme use the -DskipTests flag? Is this to make the installation faster?

  2. On installation or running local server, I am getting warnings for illegal access:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.google.inject.internal.cglib.core.$ReflectUtils$1 (file:/usr/share/maven/lib/guice.jar) to method java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain)
WARNING: Please consider reporting this to the maintainers of com.google.inject.internal.cglib.core.$ReflectUtils$1
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

Is it possible to fix the root cause of this warning?

HonzaStefanik commented 2 years ago

What version of JDK are you using (java --version)? You could also try doing mvn clean to delete any old files that could potentially cause this and then compile it again.

Paste the whole output of the mvn spring-boot:run command, maybe there will be some additional info in it (it should log the version of java among other things).

The DskipTests flag was left over as an oversight, removed as it is unnecessarily confusing

Warning persists after mvn clean. One interesting thing I noted is the warning also comes up with the mvn clean and mvn install commands.

java --version output:

Try it with Java 8 as that is the expected version, that's the only thing I can think of right now.

I still couldn't manage to reproduce it even with Java 11.0.15 though, which is kind of weird.

ViolanteCodes commented 2 years ago

@HonzaStefanik Okay, in that case, I'm fine with marking this closed - it's just a warning and it doesn't seem to affect the functionality of the application at all.
