Hey Ivan,<br>
<br>
It seems that in your case the JPA 2.0 classes are defined in a
different JAR (a different groupId/artifactId) ? <br>
Your idea might work, however, just make sure that the version
attribute in the persistence.xml defines the installed facet version
(JPAFacet_2_0 when version="2.0" and JPAFacet_2_1 when
version="2.1").<br>
<br>
Best Regards,<br>

<div>My idea is the following: if you don't have
persistence.xml, then most probably you don't have the
dependencies either. Definitely the facet is not installed, so
Forge installs it for you by adding both the persistence.xml
and the dependencies. </div>
<div><br>
</div>
<div>But if you have persistence.xml already in your project in
99% of the cases you have already setup the dependencies as
well. So the facet is there and Forge does not need to install
it.</div>

I am not sure this is enough. How can you assure that no
compilation errors would occur when @Entity or any other
JPA-related class is used?<br>

<div dir="ltr">Hi everybody,

</div>
<div>I am working on a project that is not
mainstream Java EE. Its target is Tomcat, but it
uses JPA 2.0 (Eclipselink). I have tailored the
dependencies in the pom.xml as well as the
persistence.xml.</div>
<div><br>
</div>
<div>And now I want to use Forge to add some
fields to the existing entities. What I noticed
is that when I run the jpa-new-field command for
the first time, it also installs the JPA facet.
Which in turns adds some unwanted dependencies
to my pom.xml and completely overwrites
persistence.xml.</div>
<div><br>
</div>
<div>I dig into the code and found that the
isInstalled method of the JPA Facet returns true
when persistence.xml file does not exist and
when pom.xml does not contain some dependencies.
These dependencies are different for JPA 2.0 and
2.1, but are basically Hibernate JPA API and the
Java EE API.</div>
<div><br>
</div>
<div>As a result of this, projects that don't
target Java EE or that use different artifacts
for it or for JPA are going to get their poms
polluted and their persistence.xml files
overwritten.</div>
<div><br>
</div>
<div>So my proposal is to change the isInstalled
method to only check for the presence of
persistence.xml. What do you think?</div>
<div><br>
