Hello,

The last error message is strange, I cannot explain it.

If you are not able to install Java 11 on your build machine, and prefer using Docker I recommend that you use the tested docker image for compilation. See: https://github.com/apache/james-project/#java-11

Regards,

Raphaël.

I’m back to making another attempt at building. :-)

I am not able to update my development machine to use java 11, so I am trying 
with docker like this:

docker run -it --rm --name my-maven-project -v "$(pwd)":/usr/src/mymaven -w 
/usr/src/mymaven maven:3.6.3-openjdk-11 mvn clean install


But I quickly run into this problem:

[INFO] Apache James :: Testing :: Base .................... FAILURE [ 38.634 s]

[ERROR] Failed to execute goal 
pl.project13.maven:git-commit-id-plugin:3.0.1:revision (get-the-git-infos) on 
project testing-base: Could not complete Mojo execution...: GIT-Command 'git 
describe --dirty=-dirty --match=* --abbrev=7' did not finish in 30000 milliseconds 
-> [Help 1]


The plugin doesn’t seem to work in this environment, so I skipped it by adding 
`-Dmaven.gitcommitid.skip=true` to the run parameters.

Q: Will this cause any problems once I can eventually build successfully?

New result:

[INFO] Apache James Cassandra backend ..................... FAILURE [ 57.902 s]

[ERROR] Failed to execute goal

[ERROR] Please refer to dump files (if any exist) [date].dump,

So I disabled tests and tried again.


The build continues almost to the end (60 minutes on my machine), and 
unfortunately ends with this:

[INFO] Apache James :: Server :: Web Admin server integration tests :: Common

Sadly, I still cannot run `mvn eclipse:eclipse`, so I still cannot make any 
PRs. Looks like I’ll need some help getting started, if that is possible.


Cheers,

Thanks for the clarification. That will push me in the right direction.

If I ever get it built someday, then I’ll try to remember to submit a PR to 
mention the version requirement somewhere in the docs.

I’ll just concentrate on the pre-built for now version then.

Thank you, Rene.

Is that a hard requirement? If so, then I will have to wait until we
update to Java 11 (which is not scheduled at this time), so I’ll
likely have to abandon for now.

Shouldn’t it be possible to compile in Java 8, though? This page
states that JRE8 is the requirement:

—> https://james.apache.org/server/quick-start.html
This guide is about deploying an already-compile James server.

Up to James 3.5 (which has a pending release), you could run with Java
8 JRE.

Starting with James 3.6, you'll need Java 11.

What you are trying to do is to compile it yourself, the requirements
are differents.

For some times now (probably 3.4) we use Java 11 compiler but target
Java 8.
