+# Check new versions of existing libraries in the repository
+
+As the number of libraries in the repository grow fast, it is hard to track new library versions for every library manually.
+Instead of doing this process manually, we provided a mechanism (through [a GitHub workflow](https://github.com/oracle/graalvm-reachability-metadata/blob/master/.github/workflows/check-new-library-versions.yml)) 
+that automatically scans MavenCentral repository for new versions of the libraries that we currently have.
+
+## How it works
+
+The workflow gets triggered every two weeks automatically (alternating to the automatic release weeks). Besides that, the job can be triggered manually from the GitHub actions.
+The whole process consists of the following parts:
+* Scanning of the MavenCentral
+* Running existing tests with newer versions of the library
+* Creating a pull-request that updates `tested-versions` field of the `index.json` file for libraries that passed tests with a new version
+* Creating an issue that lists all versions of libraries that failed their existing tests.
+
+As a preparation for the whole process, we are creating a branch for all successful tests, and a single issue for all failed tests.
+
+### Scanning the MavenCentral 
+
+At first, the workflow runs gradle task called `fetchExistingLibrariesWithNewerVersions`.
+The task itself does the following:
+1. Gets the list of all existing libraries in the repository
+2. For each library, it searches for the latest tested version in the corresponding library `index.json` file
+3. For the given library name, it fetches `maven-metadata.xml` file from the MavenCentral repository
+4. In the fetched `maven-metadata.xml` file, it finds the position of the latest tested version (gathered in the step 3) and returns all the versions after it
+5. As a last step, the task returns list of maven coordinates of libraries with newer versions (alongside java version and os version required for testing)
+
+### Running existing tests with newer versions
+
+Now that we have coordinates list, we are spawning a new job in GitHub workflow for each coordinate in the list.
+Each of the spawned jobs:
+1. Extracts the following parts from the given maven coordinates:
+   1. Latest version that we have tests written for 
+   2. Path to the latest tests we have
+   3. Maven coordinates of the latest tests
+2. Sets `GVM_TCK_LV` env variable to the version we want to test. This way the executed tests will use library version specified in the env variable.
+3. Run the latest test with `./gradlew test -Pcoordinates=<testCoordinates>` (with `testCoordinates` calculated in the step 1)
+
+### Aggregating results of the tests
+
+Based on the outcome of the test we:
+* Update the list of `tested-versions` in the proper library `index.json` file and commit changes to the previously created branch, if the test passed
+* Add a comment that explains which library version cannot pass the tests, in the issue we previously created
+
+Note: since the spawned jobs run tests in parallel, we have to make some kind of synchronization to avoid merge conflicts if two tests are populating the same `index.json` file.
+The whole process of synchronization is driven by the [tryPushVersionsUpdate](https://github.com/oracle/graalvm-reachability-metadata/blob/master/.github/workflows/tryPushVersionsUpdate.sh) script.
+
+At the end, when all jobs have finished their executions, the workflow just creates a pull-request based on a branch the jobs committed to.
+As a final result, we have:
+* a pull-request with updates of all new tested versions
+* an issue with list of all versions that doesn't work with existing metadata
