I was trying to deploy a test Spring Boot project to Google Cloud Run referring to this Quickstart guide by Google: https://cloud.google.com/run/docs/quickstarts/build-and-deploy/deploy-java-service
I didn't follow the guide exactly, as I write the REST endpoints myself. The project can start up locally and I am able to access its endpoint though.
What I did follow is run gcloud run deploy at the root of the project, and follow the options in Quickstart.
The process failed at "Building Container" stage. Google Cloud Build log shows that it failed when it is executing something related to fork/exec and ./gradlew. Below is a slice of the log.
Step #1: [builder] Warning: BOM table is deprecated in this buildpack api version, though it remains supported for backwards compatibility. Buildpack authors should write BOM information to <layer>.sbom.<ext>, launch.sbom.<ext>, or build.sbom.<ext>.

I tried searching online for these keywords, but I can find none. The most prevalent result is to use chmod +x ./gradlew, but I don't think I am able to do that?

As stated by @John Hanley, the short answer is not follow the tutorial. Instead, you should do the following:
1: use Maven or Gradle to build your JAR file.
2: create a Dockerfile at the root of the project. Below is a sample I used.
FROM openjdk:17-alpine
WORKDIR /app
COPY ./target/rest-demo-0.0.2-POC.jar /app
EXPOSE 8080
CMD ["java", "-jar", "rest-demo-0.0.2-POC.jar"]
3: Set up a repository in Artifact Registry, in a region of your choice, and then tag your image in the following format
<region-name>-docker.pkg.dev/<gcp-project-name>/<repository-name>/<short-image-name>
E.g.
asia-northeast2-docker.pkg.dev/playground-888888/rest-demo/rest-demo
4: should be straightforward
Along the way you may discover that you do not have certain permissions. Grant yourself those permissions and try again.
Also I didn't use this, but it may be helpful too: https://cloud.google.com/build/docs/building/build-containerize-java#gradle
