Java Installation and Configuration in Aletyx Enterprise Build of Kogito and Drools 10.1.0-aletyx

Microsoft Windows
MacOS
Linux

Install Java using Chocolatey®:
choco install temurin17

JAVA_HOME (Run in PowerShell as Administrator):

[Environment]::SetEnvironmentVariable(
    "JAVA_HOME",
    "C:\Program Files\Eclipse Adoptium\jdk-17.0.10.7-hotspot",
    [System.EnvironmentVariableTarget]::Machine)

Add Java to PATH (Run in PowerShell as Administrator):

[Environment]::SetEnvironmentVariable(
    "Path",
    [Environment]::GetEnvironmentVariable("Path", "Machine") + ";%JAVA_HOME%\bin",
    [System.EnvironmentVariableTarget]::Machine)

Verify installation (open a new PowerShell window):
java --version echo $env:JAVA_HOME

Install Java:
brew install --cask temurin17

Add Java environment variables to your shell configuration (for zsh):

echo 'export JAVA_HOME=$(/usr/libexec/java_home -v 17)' >> ~/.zshrc
echo 'export PATH=$JAVA_HOME/bin:$PATH' >> ~/.zshrc

Create a helper function to switch Java versions (optional):

echo 'function setjdk() {
    export JAVA_HOME=$(/usr/libexec/java_home -v $1)
    echo "JAVA_HOME set to $JAVA_HOME"
    java -version
}' >> ~/.zshrc

Reload shell configuration:
source ~/.zshrc
Verify installation:
java --version echo $JAVA_HOME

Install Java:

sudo apt-get update
sudo apt-get install -y temurin-17-jdk

Set JAVA_HOME and update PATH (for bash):

echo 'export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:/bin/java::")' >> ~/.bashrc
echo 'export PATH=$JAVA_HOME/bin:$PATH' >> ~/.bashrc

For zsh users:

echo 'export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:/bin/java::")' >> ~/.zshrc
echo 'export PATH=$JAVA_HOME/bin:$PATH' >> ~/.zshrc

Reload shell configuration:

# For bash
source ~/.bashrc

# For zsh
source ~/.zshrc

Verify installation:
java --version echo $JAVA_HOME

Troubleshooting

Windows
macOS
Linux

If Java command is not recognized after installation:

Open System Properties (Win + R, type sysdm.cpl)
Click “Environment Variables”
Verify JAVA_HOME exists and points to correct directory
Verify Path includes %JAVA_HOME%\bin
Open new command prompt to test

“Java command is not recognized”:

ls -l /Library/Java/JavaVirtualMachines/ # Verify Java installation

Verify JAVA_HOME

/usr/libexec/java_home -V

If Java command is not recognized:

# Check Java alternatives
sudo update-alternatives --config java

# Verify installation path
which java
readlink -f $(which java)
