Re: Importing new libraries into Synapse
[image: image.gif]Hi all,
I'm having a bit of trouble downloading new libraries by adding them to the
root pom.xml using the mvn install.
After a successful build when I tried to import the libraries into the
classes, they don't seem to be identified.
Upon inspection of the .m2 folder it seems that even though the libraries
do get imported as seen in the screenshot below from the build logs,
[image: image.png]
...the .jar files do not get imported.
[image: image.png]
Would appreciate some thoughts on how this can be resolved.
Kind regards

Re: Importing new libraries into Synapse
Posted by Andreas Veithen-Knowles <an...@gmail.com>.
Note that the root POM doesn't define any dependencies as such. It only has
a dependencyManagement section that defines the dependency versions to be
used in child modules.

...the .jar files do not get imported.
I was working on a resolution to this and found that adding the dependency
in the respective module-level pom.xml (in this case Synapse core) resulted
in the .jars being downloaded successfully. The relevant commit is linked
here:
https://github.com/n-jay/synapse/commit/684ed55a54be8ef2341f68d583bc2f19171eaa1c
I've removed all the new dependencies that I added to the root pom
previously.
The issue now is that when I try to import the library (existing in the
com/github/... location in .m2) it doesn't seem to be detected.
[image: image.png]
The jar is, however, present.
[image: image.png]
Would appreciate some thoughts on whether this is the proper way to go
about it.
Thanks and regards

Rebuilt with the inclusion of Maven central, unfortunately didn't work out:
https://github.com/n-jay/synapse/commit/3688230dc367d44bb9b187fa6505be3159f9630d
Do you have a link showing the changes in the root POM?

Re: Importing new libraries into Synapse
Posted by Senaka Fernando <se...@apache.org>.
Your point "I also noticed that the repositories included in the pom.xml is
only the WSO2 public maven repo and Maven central is not included" might
have something to do here. It would be best if you can provide a link to
the root pom you are using to validate this as well. Mevan Central has the
library
<https://search.maven.org/artifact/com.github.stefanbirkner/system-lambda/1.2.0/jar>
you are after.
Thanks,
Senaka.

Do you have a link showing the changes in the root POM?
