Unable to build WPS 3.6.2

[eduardhc]

Hi,
We are trying to build 52North/WPS (build 3.6.2 from tar.gz file) from sources, and we are encountering the following problems:

• opengeo.org repository is not available any more: this is not a big deal, as per this we learnt it needs to be changed to another URL. We have updated the relevant files and it is OK.
• geotools license problems: this is more of a problem, as we have been completely unable to resolve this. It doesn't matter what we try (with or without -Pwith-geotools, adding -Dlicense.skip, ...), we cannot finish the build without getting license check errors for the geotools-related packages. I don't know if we are missing something really stupid, or else the documentation is not up to date, but for now we are completely stuck.

Kind regards, and thank you in advance.

Hi, could you try to remove the OpenGEO repository instead of replacing the URL? Note that this has to be done in the root pom.xml as well as in the 52n-wps-io-geotools/pom.xml. If this should not work, please let me know your operating system, maven and Java version.

[eduardhc]

Hi,
I've done so in the following 4 POM files:

• ./52n-wps-io-impl/pom.xml
• ./52n-wps-io/pom.xml
• ./pom.xml
• ./52n-wps-io-geotools/pom.xml

This solves the download problems, but I still have the license problem. This is the output I'm getting after a mvn clean install (CentOS 7.6.1810, Maven 3.0.5):

I confirm that the behaviour is a bit strange also on my CentOS test environment. I will investigate this.

Thank you. Just some more info: I got rid of the license check problem the "hard way", by completely removing the reference to maven-notice-plugin from all the relevant pom files. Now I'm facing what it seems a dependency problem, here's the output:

I'm getting this no matter if I include the "-Pwith-geotools" argument in command line or not. In fact, it seems it is including the geotools stuff in either case...

Thank you very much for your help, I'm a kind of a novice regarding Maven projects...

Kind regards

[bpross-52n]

The issue might be the relatively old maven version. Using maven 3.5.4 the build worked for me on a clean CentOS 7 system.

[eduardhc]

Ok, I'll give it a try. This will complicate things a bit, as this build needs to be done from inside a docker image, so we'll need to manually set up a newer version of Maven from inside the dockerfile...

Any chance that this gets fixed for older Maven releases...?

Regards.
