I have a Raspberry Pi which I'm trying to create a Java app for.
So far I have cloned my repo into a directory on the desktop.
My app uses Gradle and I followed the instructions correctly from here to install Gradle.
I have been having issues with setting my environment variable on the Pi, for example on the Pi itself I set export PATH=$PATH:/opt/gradle/gradle-6.7/bin and gradle -v outputs the correct version. If I'm logged in to my same user, "simon", in ssh, when I echo $PATH, /opt/gradle/gradle-6.7/bin is not in the path. I don't understand why, it's the same user, logged in with the same password?
When I type in users I see three pi pi simon. I'm assuming these are different terminal sessions?
To get around this I did export PATH... through my logged in user "simon" on my win laptop ssh session, and could run gradle build, the PATH variable is again set correctly.
I cd to the directory with the project and the build.gradle file, then I run build gradle and I get an error with the build:
simon@raspberrypi:/home/pi/Desktop/slotcar_project/SlotCar $ gradle build
Starting a Gradle Daemon (subsequent builds will be faster)
FAILURE: Build failed with an exception.
* What went wrong:
Gradle could not start your build.
> Could not create service of type CrossBuildFileHashCache using BuildSessionServices.createCrossBuildFileHashCache().
> Failed to create parent directory '/home/pi/Desktop/slotcar_project/SlotCar/.gradle' when creating directory '/home/pi/Desktop/slotcar_project/SlotCar/.gradle/6.7/fileHashes'
I am guessing that my user doesn't have permission to create a folder? I have tried running the same command with sudo gradle build but I get an error sudo: gradle: command not found.
Gradle 6.7 Java openJDK 11
Edit:
build.gradle has these permissions:
-rw-r--r-- 1 pi pi 1005 Oct 29 15:43 build.gradle
My new user "simon" wasn't in the group pi so I added it and now consider how to change the file permissions for that group. Otherwise, running out of ideas.
Edit2:
Changed permissions and same error:
-rwxrwxr-- 1 pi pi 1005 Oct 29 15:43 build.gradle
As I understand this should give owner (pi) and group (I added "simon" to pi group) read, write and execute perms.
