Is it normal that pom.xml in target repository is checked ? about sortpom

[Ekryd]

Hi! I am busy the following days, so it will take some time before I can look at this for real. Thanks for your patience.
ps. it should be the source but but I haven’t experienced your problem. Is it possible to recreate in an integration test?

[sbernard31]

I will maybe find time to create an integration test that but not sure.

Waiting you could use : sbernard31/leshan#11 to reproduce that.

Thanks!

I digged a little more about this.

Explanation about why it is called twice ?
I find why the sortpom:verify goal (attached to validate phase by default) is called twice.

This is because my build also run maven-source-plugin:jar goal which :

• Binds by default to the lifecycle phase: package.
• Invokes the execution of the lifecycle phase generate-sources prior to executing itself.

First try to fix it :
To attach sortpom:verify goal to process-sources, this way maven-source-plugin will execute generate-sources and will not recall it.
==> It seems to work ✔️

Second try to fix it :
Using maven-source-plugin:jar-no-fork which does not invoke `generate-sources. (more details)
==> it seems to work too ✔️

So I guess this is not a sortpom issue.

Before to find this, I begin to write 1 IT test but I was not able to reproduce because in my IT test sortpom:verify was called twice but still on same file.

Even when I was using flatten-maven-plugin, the flattened pom file was created by not used by sortpom... 🤷

So a remaining question (not related to sortpom) is : why IT test and "real use case" behave differently ?

I let the IT test just in case :

I am glad that the problem was solved for you and thank you for posting it as an issue (in case somebody else stumbles on the same problem).
I guess that the IT test framework does some hacking in the Maven process. The IT tests themselves does not execute in the source directory, but it moves all files to the target/it directory before executing. Perhaps it also caches the pom file input instead of reading the pom between each phase??

Probably something like this. 🤷

I guess we can close this issue ?
