Root Cause

The target directory is not writable or the filesystem is full, preventing the site plugin from creating output directories.

generic

中文

目标目录不可写或文件系统已满，导致站点插件无法创建输出目录。

Workarounds

  1. 95% success Ensure the target directory exists and is writable 
    mkdir -p /path/to/target && chmod 755 /path/to/target
  2. 90% success Free up disk space or use a different output directory 
    mvn site -Dsite.outputDirectory=/tmp/site

Dead Ends

Common approaches that don't work:

  1. Changing the site output directory to a random path 70% fail

    The new path may also have permission issues or be non-existent.

  2. Running Maven as root 60% fail

    This is a security risk and may not solve filesystem full issues.
