根因分析

Java 主目录路径指向 JRE 而非 JDK，或 JDK 安装不完整。

English

The Java home path points to a JRE instead of a JDK, or the JDK installation is incomplete.

解决方案

  1. 95% 成功率 Set JAVA_HOME to a proper JDK installation 
    export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64 (ensure it points to JDK, not JRE)
  2. 90% 成功率 Install a full JDK if missing 
    sudo apt-get install openjdk-11-jdk

无效尝试

常见但无效的做法:

  1. Setting JAVA_HOME to a JRE directory 95% 失败

    JRE does not contain tools.jar, which is needed for annotation processing or certain plugins.

  2. Downloading tools.jar separately and placing it in the JRE lib folder 90% 失败

    This is not a supported configuration and may cause compatibility issues.
