DataNucleus enhancer on multimodule projects
Hi,
I just recently discovered Apache Isis and aI'm now pissed at Google Search
for not find it earlier for me (it's exactly what I needed, but incredibly
hard to come by!).
Documentation recommends that, after some playing around with the Hello
World, you go with the archetype that comes with a multimodule app. Which
is awesome as you get a nice long term structure from the start.
My problem is with the enhancer though. Following the steps to make
IntelliJ work I shall call
"mvn datanucleusenhancer -o" and there are screenshots etc but... This is
not for multimodule projects.
Of course, Option A) would be to add the task for every module I have on
the Run Configuration.
But, and the reason I write you, Is there an Option B) by which I can call
datanucleusenhancer on all modules without manually listing them?
Thanks,
marc

This is exactly what I was looking for.
Thank you very much,

Glad you sorted it out, Marc.
[1] and [2] look correct to me, though - the ":" is there. Perhaps a bit
tricky to see depending on resolution?
To answer your question more generally - and as you've probably gathered -
it's only necessary to run "datanucleus:enhance" in the modules where there
are entities. In the archetypes there is just one module - for
"helloworld" it's a one-module project anyway, while for "simpleapp" it's
the "module-simple" module.
If you choose to split out your entities across multiple Maven modules then
you will need to run "datanucleus:enhance" in all of them. Suppose you've
got modules in "module-customer" and "module-order"; then you could run the
following in the parent module:
mvn -pl module-customer,module-order datanucleus:enhance -o
Here "-pl" flag takes a comma-separated list of modules to run the enhance
goal in.
An alternative approach is to define a profile in the parent module, eg:
<profiles>
<profile>
<id>enhance</id>
<activation>
<property>
<name>enhance</name>
</property>
</activation>
<modules>
<module>module-customer</module>
<module>module-order</module>
</modules>
</profile>
</profiles>
Then you could use:
mvn -Denhance datanucleus:enhance -o
with the profile activated by the presence of the system property.

I just found out I can do
mvn datanucleus:enhance -o
From the root folder of my project.
Please note that the IntelliJ instructions, on the screenshot of the
run configutations, says "datanucleusenhance" (without the ":" in the
middle) [1] and [2]. It is properly shown in [3]

Yup, but as far as I understand, I shall have a 'dom' module inside
every application module. For example, estatio has "agreement",
"party" and "asset" modules all of which have a "dom" part.
(Note that estatio has different modules but not different Maven modules)
The recommended setup (and the one created by the archetype) is to
have different maven modules, initially: appdefn, module-base,
module-simple, webapp.
So, at the very beggining only module-simple needs enhancement. But
suppose I now clone module-simple to create my own "party" and
"agreement" modules.
At that point I'd need to enhance the three modules so I'd need to
modify my run configurations to do so (Option A) or, magically, tell
maven "run datanucleusenhance on all the submodules that have such
target"

It is also possible I did not properly understand the recommended
setup and I'm on a totally wrong path!
Thanks,
Marc

Hi Marc,
Welcome to Apache Isis!
You need to enhance only the 'dom' module, the one that contains your
domain objects.
There is no need to enhance the webapp stuff or the integration tests. I
think it won't break anything if you try to enhance them but it will slow
down your build.
