Re: How force Maven to compile each project/module even if there are
no changes
Run a clean before your compile, thus "mvn clean compile" or "mvn
clean install". This will clean out the target directory of each
project before compiling. The skipped java files is not really a maven
issue, it is the java compiler which detect which files are changed.

Re: How force Maven to compile each project/module even if there

Hi Baptiste,
Thanks for taking a look at the pom.xml.
I do have my reasons for building the WAR using ANT. Normally I would use
the required plugin for that, but since I have to hassle around a bit on the
maven server with libraries I was forced to do it this way.
But to be complete I indeed trigger the build by the following command:
-e clean install -Dload_properties -Drun_dummy_test -Drebuild_war
-Drun_tests
So as you can see the different profiles are being triggered. And normally
by calling the same maven command WITHOUT "clean" the -Drun_tests is
actually kicking off the unit tests.
But now since I added the "clean" option, none of the tests are being
executed any longer.
Strange.

I didn't understand what could prevent your tests from being run, since it's
just automatic and a kind of prerequisite of the install goal (just before
package, actually, you should read
http://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html#Build_Lifecycle_Basics
).
I just had a look at your pom. Woaw... I understand why it gets so
complicated for you... Your pom seems sooo complicated to me. I don't
completely understand why you need to run ant to create a war. But anyway.
Though it's difficult to read, I'm wondering if you didn't forget to
activate some profile? Are you sure the previous command was only "mvn
compile" and not something like "mvn compile -Drun_tests=true" ?
Cheers

Hi Nick,
Thanks for your reply.
I adjusted the maven goals/options to indeed use "mvn clean instal ....".
The result of this change was ok. All projects are now compiled even if
there are no changes.
However no none of the JUnit tests are being executed.
Normally about 400 JUnit tests are being executed, but because of the clean
command nothing is being executed now.
Do you know what I need to change to make sure the Unit tests are executed
again.
See attached pom file. At line 457 the call for the JUnit tests is
described.
Thanks.
