Add .rat-excludes file to each repository

[tkobayas]

In order to check All files have license headers if necessary. https://kie.apache.org/docs/community/verify/ , add .rat-excludes to the root directory of each repository.

• incubator-kie-drools [incubator-kie-issues-1613] Add .rat-excludes file to each repository incubator-kie-drools#6149
• incubator-kie-optaplanner kie-issues#1613: Add CI :: Check license headers GitHub Actions workflow incubator-kie-optaplanner#3130 and kie-issues#1613: Migrate CI :: Check license headers apache-rat v0.16.1 incubator-kie-optaplanner#3144
• incubator-kie-kogito-runtimes kie-issues#1613: Add CI :: License headers GitHub Actions workflow incubator-kie-kogito-runtimes#3714
• incubator-kie-kogito-apps [DO NOT MERGE][WORK IN PROGRESS]kie-issues#1613: Add CI :: Check license headers GitHub Actions workflow incubator-kie-kogito-apps#2111
• incubator-kie-kogito-images [10.0.x] kie-issues#1613: Add CI :: Check license headers GitHub Actions workflow incubator-kie-kogito-images#1811
• incubator-kie-tools [DO NOT MERGE][WORK IN PROGRESS]kie-issues#1613: Add CI :: License headers / check GitHub Actions workflow incubator-kie-tools#2746

For example, running

java -jar apache-rat-0.16.1.jar -d ./incubator-kie-drools/ -E ./incubator-kie-drools/.rat-excludes | grep "== File:" > kie-drools-rat.txt

can easily confirm license headers.

Each repository committers should add ignorable file names/paths in .rat-excludes.

Note:

• apache-rat 0.16 supports only filename with regex. e.g. .*\.csv . We cannot express file path.
• apache-rat 0.17 (as of 2024 Nov 20, it's still SNAPSHOT) supports glob pattern with --input-exclude-file option. e.g. **/optaplanner-examples/data/**/import/**

Thank you @tkobayas, I have something similar in my head longer time. What I see as we should do as part of this ticket is to unify the approach. Because there were already some initiatives to have licenses checks.

checkstyle.header.template

Used in a lot of our maven projects

I think we should avoid the situation we have in parallel use of:

• apache-rat-plugin
• checkstyle.header.template
• apache-rat java cli tool

I think we should use just one of the above, while the last seems to me as best candidate as it is not bind to maven projects. What is your opinion?

Hi @jomarko

I think we should use just one of the above, while the last seems to me as best candidate as it is not bind to maven projects. What is your opinion?

Yeah, +1 for apache-rat java cli tool.

Indeed, I merged apache/incubator-kie-drools#6149 with removing apache-rat-plugin. I think @baldimir has the same opinion, but it's good to discuss it in dev at kie.apache ML. I'll send an email very soon.

Also thanks for mentioning that checkstyle.header.template can be removed as well.

[LightGuard]

Also a +1 from me about using the CLI tool.

FYI, "kogito-images" will be not updated with "CI :: Check license headers" workflow, see the explanation here apache/incubator-kie-kogito-images#1811 (comment).
