According with the Install all spring-* jars into your local Maven cache section it indicates: ./gradlew install

In two different computers it used to work without any problem, now in both arise:

FAILURE: Build failed with an exception.

* What went wrong:
Task 'install' not found in root project 'spring-security'.

* Try:
Run gradlew tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.
Use '--warning-mode all' to show the individual deprecation warnings.
See https://docs.gradle.org/6.9/userguide/command_line_interface.html#sec:command_line_warnings

BUILD FAILED in 14s

A build scan was not published as you have not authenticated with server 'ge.spring.io'.

I had executed:

git checkout main
git fetch upstream
git merge upstream/main
git push -f origin main

So I have all updated.

Thanks for reaching out @manueljordan. I have updated the README with the correct command. Please use ./gradlew publishToMavenLocal instead.
