Building SNAP from sources : errors during the "mvn clean install"

[marpet]

Hi,
I wrote the reason for this problem in the other thread where you asked the same question. (Please do not double post.)

Server error during installation

Hi, yesterday there we had some server issues, and some still remain. Also the forum had an outtake yesterday. You might have noticed it. The repository should be available again in the course of the day.

If you use the latest dev snapshot or any other branch you always take the risk that things don’t work. It is not as stable as the released version.
And as @gnwiii already said, it is best to use the released version.
The issue [SITBX-703] S1TBX-SE-8 Spotlight interferometry support - JIRA (atlassian.net) is already resolved for version 8.0.0. So it should be included in the installed version.
