Linux quick tips

- Ensure `gradlew` is executable: `chmod +x gradlew`.
- If you get `/bin/sh^M: bad interpreter`, convert line endings: `dos2unix gradlew` or `sed -i 's/\r$//' gradlew` and re-add as LF in Git.
- If `java` is missing, install the course JDK (Temurin 25). Example (Adoptium/Temurin 25 on Ubuntu/Debian):

```bash
sudo apt update
sudo apt install -y wget apt-transport-https gpg
wget -qO - https://packages.adoptium.net/artifactory/api/gpg/key/public | sudo gpg --dearmor -o /usr/share/keyrings/adoptium.gpg
echo "deb [signed-by=/usr/share/keyrings/adoptium.gpg] https://packages.adoptium.net/artifactory/deb $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/adoptium.list
sudo apt update
sudo apt install -y temurin-25-jdk
