JUnit succeeds when run as "debug as junit test" but fails as "debug as gradle test".
I'm doing a simple hibernate test and the code all works fine when run from Eclipse normally as well as when I create a junit to test it.
But I'm now trying to run as ./gradlew test (from bash or within eclipse) and I'm having a problem with:
em.persist(jazz);

mvn dependency:tree skips an transitive dependency
I have a problem according to maven.
I have a module A, B and C. For legal reasons I am not allowed to tell the real names.
Module A has a dependency to module B, module B has a dependency to module C. They are configured this way in the poms correctly.
For some reason, if I call dependency:tree to the modul A, the module B is listed but the module C is not listed.
Module A,B and C are in scope compile. They are of packaging "jar". The local repository is fresh. The group-ids for all modules are "x". The version for all modules is "1". Maybe exclusions are made, but I do not know where....

Guice with empty Module
I'm learning Guice and I have working code, but my Module (extending AbstractModule) is empty (because I'm injecting a class not an interface). I can see that there's no overload of Guice.createInjector() which takes no params. Is there some way of not needing a module in my scenario? Not sure if:
1) it's not a big deal; you might add bindings to it later
2) using Guice with an empty module is an anti-pattern - always use interfaces (but I don't think that's correct)
3) I'm missing something....

How would I hide a specific Character in a ListArray
Basically, i'm making a simple terminal file editor, which has basic syntax highlighting. I'm facing an issue where the character used for the 'cursor' (which is controlled by arrow keys) is fucking up the syntax highlighting. I use 2 variables which store its location (currentLine, and currentColumn), so how would I hide it or something off the syntax highlighting function?

Pig Latin Project Java
Hi, I've been working on my piglatin project but there seems to be an error with one of the conditions. I'm a beginner coder so I'm not really sure where I went wrong. I have a PigLatin and PigLatinRunner classes, the runner calls a translate method in PigLatin. Along with my translate method, I have boolean methods that check for punctuation. However, my output has a problem with counting punctuation. For example in a word string of money!" it only counts the quote on the right, but disregards...

Modular Spring app can't find persistence provider
Hi, I'm trying to run my JPMS app through the command line instead of IntelliJ. I set up maven to copy all dependencies to a specified folder, so that they can be added to the module path.
I use the following command to start the app:
```
java --module-path "infodb-app-1.0-SNAPSHOT.jar;modules" --add-reads ovh.eukon05.infodb.app=ALL-UNNAMED -m ovh.eukon05.infodb.app/ovh.eukon05.infodb.app.Main -Dinfodb.sources.articlelimit=5 -Dinfodb.hibernate.db.user=sa -Dinfodb.hibernate.db.pass= -Dinfodb.hibernate.db.url="jdbc:h2:mem:db1;DB_CLOSE_DELAY=-1"...
