I work on a team with a bunch of git repos that are Java, Maven, and Spring
Boot projects. We all configure Eclipse somewhat similarly, although I'm sure
many of the other developers on the team have variations that I don't expect.
We install the Spring IDE and Groovy plugins, and we (not all of us) are on
2019-06.
There is one project that occasionally presents problems, perhaps because it
has one additional element that other projects don't have. It uses the
"jsonschema2pojo-maven-plugin" and "build-helper-maven-plugin" to generate
class files for json marshalling.
Typically, when I import projects, I right-click on the git repository entry
and select "Import Projects...". This works fine for almost everything I work
on, but it occasionally has trouble with this project. I had this working in
my workspace, but another developer reported problems with this, and I couldn't
get it to work on his, so I removed my imported project (which was currently
working fine), along with the .project, .classpath, and .settings, and tried
importing it again, and it's not working properly, similar to what he is seeing.
I've now tried importing the project both with "Import Projects..." and "Import
Existing Maven Projects", and the results are basically the same. The result
is that it doesn't think it's a Java project, and it doesn't recognize the
existing src/{main,test}/java folders, not to mention the target/java-gen
folder where the generated classes are stored. It does acknowledge it's a
Maven project, but nothing works because of those other problems.
Fortunately, I have a workaround, but it's not very good. I simply ask someone
else who has this project opened, who does not have this problem, to send me
their .project and .classpath files, and I copy them in, and then reimport the
project. It is now fine.
If it will help, right now I could provide the .project and .classpath file
that we need for it to work. I could iterate through this scenario again
(first saving those two files in a safe place) and produce the original
resulting dot files, if you think that would be useful.
