    Description

      [ERROR] Failed to execute goal org.apache.maven.plugins:maven-install-plugin:3.1.1:install (default-install) on project foo.bar: Execution default-install of goal org.apache.maven.plugins:maven-install-plugin:3.1.1:install failed: Could not acquire lock(s) -> [Help 1]

      I am using maven 3.9.4 on windows:

      $ mvn -v
Apache Maven 3.9.4 (dfbb324ad4a7c8fb0bf182e6d91b0ae20e3d2dd9)
Maven home: D:\projects\test\software\mvn
Java version: 17.0.5, vendor: Eclipse Adoptium, runtime: D:\projects\test\software\java
Default locale: en_US, platform encoding: UTF-8
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

      I searched for this bug and found issues like MRESOLVER-332 that first look identical or similar but do not really seem to be related so I decided to create this issue.

      For this bug I made the following observations:

      • it only happens with concurrent builds: mvn -T ...
      • is seems to be windows related (at least mainly happens on windows)
      • it is in-deterministic and is not so easy to create an isolated and simple project and a reproducible scenario that always results in this error. However, I get this very often in my current project with many modules (500+).
      • it is not specific to the maven-install-plugin and also happens from other spots in maven:

      I also got this stacktrace:

      Suppressed: java.lang.IllegalStateException: Attempt 1: Could not acquire write lock for 'C:\Users\hohwille\.m2\repository\.locks\artifact~com.caucho~com.springsource.com.caucho~3.2.1.lock' in 30 SECONDS
