--------------------------------

             Summary: Maven install failure with multi-threads(-T option) 
                 Key: MNG-7365
                 URL: https://issues.apache.org/jira/browse/MNG-7365
             Project: Maven
          Issue Type: Bug
          Components: Command Line
    Affects Versions: 3.8.1
         Environment: 1. Operating System & Hardware
macOS Monterey 12.0.1
with 6-Core Intel Core i5

2. JDK version
openjdk version "1.8.0_292"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_292-b10)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.292-b10, mixed mode)

            Reporter: Jiseong Bak
         Attachments: karaf_install_multi_thread.log, karaf_install_single_thread.log

I found that build failure occurs with multi-threads, using `-T` option. I'm the researcher on automated software engineering and faced this problem while running a script that installs vast amount of open-source projects using Maven.

This happens on one project, [karaf|https://github.com/apache/karaf]. If I find other cases like this, I'll investigate and report them for discussion here. Currently, I'm not sure why this corner case happens.

 

```bash

mvn clean install -DskipTests -V # success

mvn clean install -DskipTests -V -T 6 # failure

```
