On my Ubuntu Linux box, at the end I also have succeeded to compile the 
project. It required some actions. First, no JAVA_HOME is defined, so 
the build failed. For that, launch maven defining it:

JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64 mvn -DskipTests clean package

The build then failed at:

mock-smtp-server: Building image tarball failed, perhaps you should make 
sure your credentials for 'registry-1.docker.io/library/openjdk' are set 
up correctly. See 
https://github.com/GoogleContainerTools/jib/blob/master/docs/faq.md#what-should-i-do-when-the-registry-responds-with-unauthorized 
for help:

 From the help, my installation has docker-credential-secretservice, so 
this is added to the .docker/config.json:

|{"credsStore":"||secretservice"}|

Trying again, it came another error related to reaching the maximum 
number of openfiles:

[ERROR] 
/home/pablo/dev/jp/james-project/server/container/guice/cassandra-rabbitmq-guice/src/main/java/org/apache/james/modules/DistributedTaskManagerModule.java:[43,8] 
error while writing 
org.apache.james.modules.DistributedTaskManagerModule: 
/home/pablo/dev/jp/james-project/server/container/guice/cassandra-rabbitmq-guice/target/classes/org/apache/james/modules/DistributedTaskManagerModule.class: 
Too many open files

For this one, I increased that number in /etc/sysctl.conf

fs.file-max = 2097152

And in the bash session,

ulimit -n 4096

Check it: ulimit -aHS

After that, the james-project finally compiled.
