I'm trying to build a Java project with maven image with Gitlab-runner. There was no issue until yesterday, I encountered the error below saying that "Permission is denied".
This is the command that I run:
mvn clean install -P prd -Dmaven.test.skip=true
But once I add -X option to the command, the build suddenly works.
How on earth is debug mode related to the permission of a user?
Since I'm pretty new to programming, I have a near-zero foundation in how build works but this issue seems to be something unheard of.
Can anyone give an insight on this?
Thank you.

I've changed the Maven compiler version but didn't work, Checked permission for the Gitlab-runner account and it was fine, tried to use sudo when running the command, but that didn't work either.
Apparaently the maven was writing files to /tmp folder, I don't know the details, would be good if someone can elaborate on this.
But since the /tmp folder was belong to root and so gitlab-runner had no permission to write files to the folder,
I've changed the permission for all users to write and boom no more errors.
Got the answer from the questions below !
