The script:
1. resolves its own directory,
2. checks that `java` is available and is JDK 17+,
2. uses JDK 17 or JDK 21; on macOS it auto-selects an installed 21/17 via `/usr/libexec/java_home` when the active Java is unsupported,
3. uses the repository Gradle wrapper when present, otherwise system `gradle`,
4. runs `gradle build` for this standalone sample.
Kotlin 2.1.0 / this Gradle setup does not work with newer Java versions such as `26.0.1`. If your default `java -version` is 26, install JDK 21 or 17 and either let `build.sh` auto-detect it or export `JAVA_HOME` explicitly:
```bash
brew install --cask temurin@21
export JAVA_HOME=$(/usr/libexec/java_home -v 21)
./test/sageclient/build.sh
```
Extra Gradle arguments can be appended, for example:
```bash

Install a supported JDK and rerun, for example on macOS:
brew install --cask temurin@21

If JDK 17/21 is already installed, set JAVA_HOME before running build.sh.
