maven3.8.2 build instructions for Jersey 3.0.1

[pkcs11newbie]

Hello

I'm looking for instructions to build jersey source code using maven.

So far,

1. Installed and setup maven (3.8.2)
2. Downloaded jersey source code from https://github.com/eclipse-ee4j/jersey/tree/3.0.1 and Unzipped it ( ex: D:\workdir\XXX\jersey3.0.1\jersey-3.0.1)
3. D:\workdir\XXX\jersey3.0.1\jersey-3.0.1>mvn package -Dmaven.test.skip=true -PcheckstyleSkip

I ran into issue in regards to directory-maven-plugin:0.3.1:highest-basedir (directories), which after a lot of googling, came across stackoverflow user who suggested to use directory-of goal.
Attaching modified pom.xml for reference.
pom.txt

My expectation was to download jersey source code and built it using maven and generate the jersey jars that we need in our application. I wasn't expecting to make any changes to pom.xml, but then again I haven't much experience with maven. So, any help will be greatly appreciated.

Thanks..

Note that you can use git instead of zip (if you are not familiar with it):
git clone https://github.com/eclipse-ee4j/jersey.git <dir>
git checkout 3.0.1 to get 3.0.1
and then use maven.

I tried your way, but I could not reproduce your issue. Your output log, however, complains about org.apache.maven.plugins:maven-resources-plugin, and the copy-legaldocs execution. You may remove whole execution, it just adds legal documents to the jars.

Also you do not need to build Jersey, you may just download the jars from maven central.

Hello,

Thank you for your response.

FYI, I removed the execution block as you mentioned, it still gave me the NPE issue.
Removed all executions from maven-resources-plugin artifactid
pom.txt
That seemed to do ok for a while but then gave me below error:
[ERROR] Bundle org.glassfish.jersey.core:jersey-common:jar:3.0.1 : Input file does not exist:

Just out of curiosity, what version of maven did you use ? Maybe I can try with that.

Appreciate your help.

Thanks...

I tried with 3.8.2, it worked fine. Now maven-bundle-plugin in pom.xml has
<Include-Resource>{maven-resources},${project.build.directory}/legal</Include-Resource>. try to remove ${project.build.directory}/legal.

Did you acciddently erase the NOTICE.md and LICENSE.md files?

I'm sorry to bug but I think source of my problem is directory-maven-plugin not able to set the Highest basedir. I'm not sure why that could be the case.

I reverted all the changes to original pom.xml: pom.txt

If I modify the goal to be 'directory-of' ( or execution-root' ), in that case I think the relevant jars I'm looking for got built but fails for jersey-examples.

Thank you again for all your help..

I have tested it with maven 3.8.2 and it worked for me, but we have a report that the directory-maven-plugin works well only with maven 3.6.x. Can you test it?

[jansupol]

It really looks like on some OS, directory-maven-plugin did not work with maven 3.8.2. Fortunately, there is recently version 1.0 of directory-maven-plugin released, which seem to working fine.
