Backend failures are not reported properly

Here is a sample command one can run against a local instance:

 curl -v http://localhost:8080/starter.tgz -d dependencies=web,jpa,h2,lombok -d artifactId=service-school -d name=service-school -d groupId=com.mikzuit.developer -d javaVersion=14 -d language=java -d type=maven-project -d baseDir=java-springboot-project -o java-springboot-project.tgz

This leads to a 404 and the following in the logs:

This should be reported as a 500 with the relevant information or, better yet, we should find a way to handle such use cases with tgz format.

Hi @snicoll , I am a first time contributor looking to submit a PR to help resolve issues in the spring initializer project. I discovered an easy fix for long filename support of tar archives using a POSIX configuration.

ProjectGenerationController.java

final TarArchiveOutputStream taos = new TarArchiveOutputStream(new GzipCompressorOutputStream(output));
taos.setLongFileMode(TarArchiveOutputStream.LONGFILE_POSIX);
return taos;

Let me know if this solution makes sense, but I wrote an integration test that proves that the config works on my Mac at least. If you agree, then I can open to PR and maybe you can guide me through the process a bit in the spirit of Hacktoberfest.

The underlying issue has been fixed now but the lack of proper report remains. That being said, I can’t reproduce it with the sample so I suspect that our Web UI arrangement is actually prevent the error to be reported properly.
