Question

I am using Maven 3.0.5 and Spring Tool Source 3.2 with Maven plugin installed. When I try to do \'Run As---> Maven install\', I am getting

Answer 1

It's really incredible to be oblige to erase whole .m2/repository content. I suggest to type this command (On Windows) :

mvn clean

mvn -X package > my_log_file.log

The last command enable Debug option et redirect output to a file. Open the file and search ERROR or WARNING key words. You can find this kind of expression :

DEBUG] =======================================================================
[WARNING] The POM for javax.servlet:javax.servlet-api:jar:4.0.0 is invalid, transitive dependencies (if any) will not be available: 1 problem was encountered while building the effective model for javax.servlet:javax.servlet-api:4.0.0
[FATAL] Non-parseable POM C:\Users\vifie\.m2\repository\net\java\jvnet-parent\3\jvnet-parent-3.pom: processing instruction can not have PITarget with reserved xml name (position: END_TAG seen ...\n\n\n\n\n\n\n\n

It's esay in this case to understand you have just to delete directory C:\Users\vifie.m2\repository\net\java\jvnet-parent\3

Relaunch compilation, packaging and so on :

mvn package

WARNING disappear just because you delete POM file corrupted at the good location and maven re download it. Normally the new POM file is better.

Often debug mode give you messages with more comprehensive details.

Why I redirect log to a file : Simply because on Windows console don't have enough buffer to store all lines and often you cannot see all lines.
