Getting "Compilation Error: No compiler is provided", but Maven and Atlas Java homes both set to JDK

[Trevor Thackston]

I'm trying to follow this tutorial, but when I try to build even the skeleton generated by atlas-create-jira-plugin, I get the following compilation error:

[INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------

But Atlas sees Java home as a JDK:

C:\development\workspaces\branch\MyViewTab>atlas-version
ATLAS Version:    6.2.2
ATLAS Home:       C:\Applications\Atlassian\atlassian-plugin-sdk-6.2.2

And so does Maven:

So I'm not sure where the problem here is coming from. Does anyone have any experience with this issue and know where else there might be a configuration error that could lead to this? I am on Windows 7; my JAVA_HOME environment variable is set to "C:\development\environments\Java\jdk1.8.0_72".

[Trevor Thackston · Accepted solution]

The error, should anyone else come across this, is that my JRE install had managed to overwrite my JDK's /bin folder. To verify if your issue is coming from the same problem, try executing javac -version and see what happens. If javac doesn't exist or looks like it's too early of a version, reinstall the JDK and make sure you're not installing the JRE over it when you're prompted to install the JRE afterwards.

[Derek White]

FYI: This is 100% user error. I did it too, so don't feel bad.

If you follow the instructions (https://developer.atlassian.com/server/framework/atlassian-sdk/install-the-atlassian-sdk-on-a-windows-system/) they clearly indicate that you should have this set PRIOR to installing the SDK.

The fact that, as a side-effect of not having it pre-set, the SDK will set it to the JRE is 100% a problem on Atlassian's side that they should still resolve.

IMO, the installer should hard fail if it is not set.

I've just come across this exact error in the create jira plugin use case, but reinstalling the JDK doesn't fix it. There are two separate folders with respective bin folders. 

jdk1.8.0_131

jre1.8.0_131

[Chris Pearson]

Hi Miles. I saw this as well; in my case there were two JAVA_HOME variables.  One was a user variable and one was a system variable. The user variable pointed towards the Atlassian SDK (C:\Applications\Atlassian\atlassian-plugin-sdk-6.2.14\jre)  while the system variable pointed towards the jdk1.8.0_131 (C:\Program Files\Java\jdk1.8.0_131). 

Rather than deleting the user variable, i updated it to point to the java path instead of the Atlassian path.

This resolved my issue.

[stevemanderson]

This was my issue. Thanks for this.

[Josh Lyon]

Thanks for sharing your comment, @Chris Pearson - I had the same issue and ended up deleting the user variable (which pointed to the JRE) as I had just recently created a system variable pointing to the JDK.

[Prasanth GRN]

I moved the java bin path to the starting of the PATH environment variable in System and User Variables.  Initially, only the system variable was updated as per atlas docs.  But after setting the user variable, I was able to run the atlas command without issue (atlas-run).  Thanks Chris for your suggestion.  It made me to update the user PATH. variable.

Thank Chris Pearson, that solved the issue.

Atlassian should fix this.

[Jens Kisters __SeibertSolutions]

I just noticed that the Atlassian SDK installer also overwrites the JAVA_HOME with an path pointing to its own JRE

[Derek White]

This is exactly what I came here to report. This is atrocious.

This is the 3rd issue I have found with the SDK on Windows today. Some of them have existed for over 2 years. (I just started using it today.)

My experience thus far has been extremely frustrating and demoralizing. Atlassian is going down. Fast.

[Derek White]

Not that I have any hope of it being fixed, but I created an issue: https://ecosystem.atlassian.net/browse/ATLASSDK-191

Please vote/watch/add your opinion to it.

@Jens Kisters __SeibertSolutions @Derek White How to work around this? I'm using win10, have set system env variable JAVA_HOME to my JDK install dir: C:\Program Files\AdoptOpenJDK\jdk-8.0.242.08-hotspot, yet even after a reboot, I still get:

PS C:\Users\tblack> echo $Env:JAVA_HOME
C:\Applications\Atlassian\atlassian-plugin-sdk-8.0.16\jre

[Tim Black]

FWIW, my workaround is to use Linux for Atlassian Development.  

[Derek White]

@Tim BlackI would only guess to check system env vars, user env vars, and a reboot.

I also switched to Linux. A co-worker was able to use Windows 10 after a few fixes to the scripts, so I do know it is possible.

[Ignat]

@Derek White 

to check system env vars, user env vars, and a reboot.

- that helped in my case (after reboot). Thanks

I've come from the future to relay that @Chris Pearsonsolution is still on the money.
