maven install error


while doing maven install i got below error
No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

while doing maven clean it is success though
i follwed below steps to resolve

 maven clean
maven install
maven update
are different?
why maven clean is success and no issues in doing maven update as well where as maven install complained above jre?

maven clean essentially cleans (deletes) classes and artifacts from "target" (output) directory.

maven update / install do actually some other work beyond that with your code: compiles/packages/installs into local repo and that's where it needs JDK (maven itself does not need that, JRE is sufficient for it)

that's a good read:
