How can I start using nar maven plugin?

[Henrik Jönsson]

Hi,

I'm a new user of the nar plugin. It looks like a very interesting plugin for our c/c++ based components. However, I'm a bit confused where to start.

Which repository can I point out to download the plugin (or do I have to do something manually)?

(I'm a maven newbie as well...)

Best regards

Henrik

Hi Henrik,

We set up a 3rd-party repsitory and deployed an intermediate version:

<dependency>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>nar-maven-plugin</artifactId>
<version>3.0.0-scijava-2</version>
</dependency>

You will also have to add this section to your pom.xml so that our
repository can be found:

<repositories>
<repository>
<id>imagej.releases</id>
<url>http://maven.imagej.net/content/repositories/releases</url>
</repository>
</repositories>

Ciao,
Johannes

Hi Henrik,

Sorry, copy-paste error. It should read

<repositories>
<repository>
<id>imagej.thirdparty</id>
<url>http://maven.imagej.net/content/repositories/thirdparty</url>
</repository>
</repositories>

of course.

My bad,
Johannes

Hi Henrik,

As Johannes says, my group released our own unofficial version, for use with our projects, which you (and anyone) are welcome to use. It will probably be awhile before we get an official 3.0.0 version into Central...

If you would like a working example on how to configure nar-maven-plugin, you can find our project which uses it at:

    https://github.com/imagej/imagej-launcher

We have this working with a Jenkins farm that compiles for Win, OS X and Linux 32-bit and 64-bit builds, thanks to Johannes's hard work [1].

Regards,

Curtis

Thanks for your responses. I'll try your examples and get back if I have any problems.

Thanks for putting a version out there, Johannes!

Small correction to your snippet, since we are talking about a plugin here:

    <pluginRepositories>
        <pluginRepository>
            <id>imagej.releases</id>
            <url>http://maven.imagej.net/content/repositories/thirdparty</url>
        </pluginRepository>
    </pluginRepositories>

I was wondering though, is the current snapshot available in a repo somewhere or do I just have to build it myself?

Technically, it was Curtis Rueden who put it out.

Sorry, what exactly did you change?

As mentioned, it is available from ImageJ's thirdparty repository:

http://maven.imagej.net/content/repositories/thirdparty/org/apache/maven/plugins/nar-maven-plugin/3.0.0-scijava-2/nar-maven-plugin-3.0.0-scijava-2.jar

Well, then: thank you Curtis!

You used 'repositories'- and 'repository'-tags, but a for plugin you should use 'pluginRepositories'- and 'pluginRepository'-tags.

As mentioned, it is available from ImageJ's thirdparty repository:

        http://maven.imagej.net/content/repositories/thirdparty/org/apache/maven/plugins/nar-maven-plugin/3.0.0-scijava-2/nar-maven-plugin-3.0.0-scijava-2.jar

That's a release version, but I was wondering if there are snapshots available. Eg from nightly builds or something...

Ah, but of course!

As we struggle to reduce our -SNAPSHOT dependencies in the interest of
reproducible builds: no, we do not have nightly builds.

There is a BuildHive job that builds the nar-maven-plugin whenever
somebody updates master, but it also builds whenever a pull request is
opened, so even if we could maintain a Maven repository from that (which
BuildHive does not support), you should not rely on that:

https://buildhive.cloudbees.com/job/maven-jar/job/maven-nar-plugin/

So to answer your question: I am not aware of any Maven repository
reflecting nightly builds.

Hi all,

I believe duns used to maintain a Maven repository with SNAPSHOT builds of the NAR plugin. At first I thought it might be valuable to do so again so that people can more easily test changes. But the more I think about it, the less useful I think it actually is. Even if we set up such a thing, it would be SNAPSHOTs based on the master branch. So e.g. you wouldn't be able to test pending PRs that way. And thanks to Java and the Maven build system, cloning the NAR plugin source and running "mvn install" to have your own local SNAPSHOT for testing (from whichever branch you wish, or even multiple merged branches, whatever) is nice and easy on all popular OSes.

So in short, I think given the lack of time of the maintainers, and the fact that it really is not a requirement for testing, let's not worry about publishing SNAPSHOT builds.

Other opinions?

Regards,
Curtis

Hi,

I'm struggling to use the 3.0.0-scijava-2 repository artifact. My Nexus repository only seems to be able to index maven-nar-plugin and not nar-maven-plugin. Could this be because

http://maven.imagej.net/content/repositories/thirdparty/org/apache/maven/plugins/maven-metadata.xml

only contains

<metadata>
<plugins>
<plugin>
<name>Maven NAR Plugin</name>
<prefix>nar</prefix>
<artifactId>maven-nar-plugin</artifactId>
</plugin>
</plugins>
</metadata>

Thanks,
Mark.

Hi Mark,

Is your project public? I would like to compare the output of your
project's build with the output of
https://github.com/imagej/imagej-launcher

OTOH you can also compare them yourself if you do not want to share your
code with us.

Ciao,
Johannes

[Mark Bowman]

Johannes,

Thanks for the response. The problem appears to be entirely at my end. I think I must have misconfigured my nexus repository. imagej-laucher now builds successfully.

Thanks again,

Mark.
