Root Cause

The version string contains leading or trailing whitespace, which is not allowed by Maven's version parser.

中文

版本字符串包含前导或尾部空格，Maven 版本解析器不允许。

Workarounds

  1. 100% success Trim whitespace from the version string in pom.xml 
    <version>1.0.0-SNAPSHOT</version> (no trailing spaces)
  2. 95% success Use a properties file to define the version without whitespace 
    <properties><lib.version>1.0.0-SNAPSHOT</lib.version></properties> and reference ${lib.version}

Dead Ends

Common approaches that don't work:

  1. Using a different version without whitespace but not the intended one 80% fail

    The dependency may not exist at that version, causing a resolution error.

  2. Ignoring the error and hoping it works 99% fail

    Maven will fail to parse the version and abort the build.
