Configurable Dependencies for Maven Plugins?
Hi all,
is there a way to provide users of a plugin a way of easily switching
dependencies of it?
Background: I'm developing a Maven plugin (jQAssistant) that comes with
a dependency to Neo4j (graph database). Currently I'm using Neo4j 2.3.x
which has been compiled against Java 7 but I would like to offer users
of the Maven plugin an easy option to use the newer Neo4j 3.x releases
which offer some new features but require Java 8.
I know that it's possible to overwrite an existing dependency for a
plugin, e.g.
<plugin>
<groupId>com.buschmais.jqassistant</groupId>
<artifactId>jqassistant-maven-plugin</artifactId>
<version>1.3.0</version>
<dependencies>
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j</artifactId>
<version>3.1.3</version> <!-- instead of the default 2.3.10 -->
</dependency>
</dependencies>
</plugin>
The problem is that in my case the old version comes with another set of
dependencies than the new one:
old:
<dependencies>
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j</artifactId>
<version>2.3.10</version>
</dependency>
<dependency>
<groupId>org.neo4j.app</groupId>
<artifactId>neo4j-server</artifactId>
<version>2.3.10</version>
</dependency>
<dependency>
<groupId>org.neo4j.app</groupId>
<artifactId>neo4j-server</artifactId>
<classifier>static-web</classifier>
<version>2.3.10</version>
</dependency>
</dependencies>
new:
<dependencies>
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j</artifactId>
<version>3.1.3</version>
</dependency>
<dependency>
<groupId>org.neo4j.app</groupId>
<artifactId>neo4j-server</artifactId>
<version>3.1.3</version>
</dependency>
</dependencies>
Is there a good way to deal with it such that a user of the
jqassistant-maven-plugin can easily switch between both variants?
Cheers,
Dirk

Hi Lennart,
it works, thanks for the hint!
Now fighting with classloading problems of Apache Lucene (which is used
by Neo4j), but that's another story...
Cheers and happy easter to everybody

Hi Lennart,
that sounds feasible, will give it a try and come back with the result.
Thanks so far to all of you!

Re: Re[2]: Configurable Dependencies for Maven Plugins?
Posted by Lennart Jörelid <le...@gmail.com>.
Hello Dirk,
There are always options for doing this, although they may not be
considered elegant.
To solve your problem in a practical way I would recommend defining two
profiles within your pom (say "neo4jV2" and "neo4jV3").
One of the properties should be included ("Conditional profiles") using the
value (or existence/non-existence) of a command-line property (typically
something like -Dneo4jVersion=2).
The neo4jv2 profile includes the three neo4j2 dependencies, and the neo4jv3
profile includes the two neo4j3 dependencies.
Include the neo4jV3 profile unless the property "neo4jVersion" is set on
the command line.
Done.

Re: Re[2]: Configurable Dependencies for Maven Plugins?
Posted by Dirk Mahler <di...@buschmais.com>.
Hi Stephen,
I need to declare the dependency to static directly, so I'm on the Sorry-Out-Of-Luck path...
But your suggestion makes me thinking of providing an artifact myself (just pom packaging) in two different versions that pulls in the different dependencies and which can be overridden by the user. This should be possible then, right?
In that case I have to think about how to organize my own builds because I assume that within one reactor I won't be able to build two modules with same groupId and artifactId but different versions.
Cheers,
Dirk

Do you declare a direct dependency on static or a transitive one?
If direct, then yes you are Sorry-out-of-Luck
If transitive, then the <dependency> in the user's <plugin> will override
the neo4j-server and you are sorted as the newer version will not pull in
the static stuff

Re[2]: Configurable Dependencies for Maven Plugins?
Posted by Dirk Mahler <di...@buschmais.com>.
Hi Bindul,
sadly it's not that easy (or it's so easy that I don't see the
solution...). As a default and for compatibility reasons I'd like to
declare the dependencies of the Neo4j 2.x artifacts for my Maven plugin:
- org.neo4j:neoj
- org.neo4j.app:neo4j-server
- org.neo4j.app:neo4j-server:static *
For a user it would be possible to override only the first two
dependencies with the Neo4j 3.x versions: the third artifact (*) does
not exist for Neo4j 3.x (the Neo guys merged the static content into
neo4j-server.jar, i.e. into the main artifact without classifier). In
this case I would need to exclude "org.neo4j.app:neo4j-server:static"
which is still there as a 2.x artifact and pulls in some other deps that
are conflicting with the 3.x stuff. Any idea?
Cheers,
Dirk
