Jhipster 5.7 microservice failed to start on windows with error CreateProcess error=206, The filename or extension is too long

I have created a Jhipster micro service. when I am trying to start, I get error CreateProcess error=206, The filename or extension is too long. All other questions are suggesting to reduce classpath or usning IntelliJ. None of them explained how. Here are few things I have trying:

1. Remove Unnecessary jar from classpath:

   • I have fresh Jhipsterap. I don't know which jar I can remove without breaking it.

2. Use IntelliJ

   • I am running the service from command line.

3. Move your project or maven repo to "c:" drive to make path short.

   • I can't. The repo is huge and is being shared.

Let me know if there is any other solution for this problem.

Thanks

Answer 1

There is fairly simple way of reducing classpath on windows, if you can not move your local repo. Here is how:

Open command prompt and execute this command

mklink /J c:\repo C:\<long path to your maven repository>

This will create a link to your maven repository. Now run the service like this:

mvn -Dmaven.repo.local=c:\repo spring-boot:run

Thats all. Now your classpath will be reduced by around 10000 characters (tried for jhipster gateway app).

Good luck.

Forking is enabled by default since Spring Boot 2.2. See Since 2.2.0 spring-boot-maven-plugin create 2 java process (may cause CreateProcess error=206). Need workaround to fix it question and solution
