Ich wollte Temurin JDK 8 und 11 installieren, ich habe sie mit diesen Schritten installiert
wget https://github.com/adoptium/temurin8-binaries/releases/download/jdk8u312-b07/OpenJDK8U-jdk_x64_linux_hotspot_8u312b07.tar.gz
tar xzf OpenJDK8U-jdk_x64_linux_hotspot_8u312b07.tar.gz
sudo mv jdk8u312-b07/ /usr/lib/jvm/temurinjdk-8-hotspot-amd64
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/temurinjdk-8-hotspot-amd64/bin/java" 1081
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/temurinjdk-8-hotspot-amd64/bin/javac" 1081
Ich bin mir jedoch nicht sicher, ob das 100 % richtig ist und wie ich eine .jinfo-Datei erstelle. Ist das überhaupt erforderlich?
Antwort1
Du kannst den ... benutzenAdoptium Debian/Ubuntu-Repository
Fügen Sie den Eclipse Adoptium GPG-Schlüssel hinzu
wget -O - https://packages.adoptium.net/artifactory/api/gpg/key/public | sudo apt-key add -
Fügen Sie das Eclipse Adoptium apt-Repository hinzu
echo "deb https://packages.adoptium.net/artifactory/deb $(awk -F= '/^VERSION_CODENAME/{print$2}' /etc/os-release) main" | sudo tee /etc/apt/sources.list.d/adoptium.list
Installieren Sie die gewünschte Temurin-Version
sudo apt update # update if you haven't already sudo apt install temurin-8-jdk sudo apt install temurin-17-jdk
Konfigurieren der Standardversion
sudo update-alternatives --config java

Ich habe das Skript aus dem ursprünglichen AdoptOpenJDK-Debütpaket extrahiert und die von mir verwendete Version wie folgt geändert:
wget https://github.com/adoptium/temurin17-binaries/releases/download/jdk-17.0.1%2B12/OpenJDK17U-jdk_x64_linux_hotspot_17.0.1_12.tar.gz
mkdir -p /usr/lib/jvm
sudo tar -xvvf OpenJDK17U-jdk_x64_linux_hotspot_17.0.1_12.tar.gz -C /usr/lib/jvm/
sudo ./java-alternative install /usr/lib/jvm/jdk-17.0.1+12
sudo ./java-alternative set /usr/lib/jvm/jdk-17.0.1+12
…
sudo ./java-alternative remove /usr/lib/jvm/jdk-17.0.1+12
