首次在Windows使用Apache Isis，Simple-app执行clean install失败

Hey there, sorry to hear your Apache Isis project build is hitting a snag! Since you haven’t shared the specific error output from Maven, let’s go through the most common culprits and fixes to get your build back on track:

• Confirm Maven & Java Version Compatibility
  Apache Isis 1.16.2 has strict runtime requirements:

  • You’ll need Maven 3.3.9 or newer—verify your version with:

    mvn -v
    

  • It also requires Java 8 (JDK, not just JRE). Check your Java version and ensure JAVA_HOME points to a valid JDK 8 installation:

    java -version
    echo %JAVA_HOME%  # For Windows
    

• Fix Network/Repository Issues
  Maven needs to pull dependencies from central repositories, which can fail if you’re behind a proxy or have cached corrupted files:

  • Force a refresh of dependencies with the -U flag to bypass stale cached artifacts:

    mvn clean install -U
    

  • If you’re on a corporate network, update your Maven settings.xml (located in C:\Users\<YourUsername>\.m2 or your Maven installation’s conf folder) with proxy credentials.
  • As a last resort, delete the entire .m2/repository folder to clear corrupted cached files, then re-run the build.

• Get Detailed Error Output
  The -B (batch) flag suppresses verbose logging, so you’re missing critical details about why the build failed. Run the build without it to see full error messages:

  mvn clean install
  

  Look for lines starting with ERROR or Failed—common issues include missing dependencies, plugin conflicts, or invalid project configuration. Sharing these specific errors will make troubleshooting much faster.

• Validate Archetype Generation Command
  I noticed a small typo in your original archetype command: there’s an extra space in -D archetypeArtifactId (it should be -DarchetypeArtifactId with no space). While the project was created, this might have caused partial configuration issues. If other fixes don’t work, re-generate the project with the corrected command:

  mvn archetype:generate "-DarchetypeGroupId=org.apache.isis.archetype" "-DarchetypeArtifactId=simpleapp-archetype" "-DarchetypeVersion=1.16.2" "-DgroupId=com.mycompany" "-DartifactId=myapp" "-Dversion=1.0-SNAPSHOT" "-B"
  

If you can share the exact error messages from the Maven build, I can help you pinpoint the exact issue and fix it quickly!
