Compile not Found

⚠️ Error: Compiler Not Found di HGrid247

📌 Causes

This error occurs because:
➡️ The JVM running HGrid247 uses the JRE (Java Runtime Environment)
➡️ The JRE does not have a Java compiler (javac)

Meanwhile, the workflow compilation process in HGrid247 requires a compiler .

🎯 Ultimate Solution

Use JDK (Java Development Kit) , not JRE.

🖥️ How to Fix it on Windows

Steps:

Open Command Prompt
Go to the HGrid247 folder

Run:

    %JAVA_HOME%\bin\java -jar HGrid247-3.5.jar

Example:

    "C:\Program Files\Java\jdk1.8.0_80\bin\java" -jar HGrid247-3.5.jar

🐧 How to Fix it on Linux

Steps:

Open terminal
Go to the HGrid247 folder

Run:

    $JAVA_HOME/bin/java -jar HGrid247-3.5.jar

Example:

    /usr/lib/jvm/java-8-openjdk-amd64/bin/java -jar HGrid247-3.5.jar

🔧 Best Practice (Recommended)

1. Set Environment Variable

Windows:

    JAVA_HOME = C:\Program Files\Java\jdk1.8.0_80

Add to PATH:

    %JAVA_HOME%\bin

Linux:
Add to .bashrc:

    export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
    export PATH=$PATH:$JAVA_HOME/bin

2. Check Installation

    java -version
    javac -version

✔️ If javac→ appears, it means you are using JDK

🧠 Important Insights

    Component       Function
    ---------------------------------
    JRE             Running Java programs
    JDK             Run + Compile Java

👉 HGrid247 requires JDK because it generates & compiles workflows
