Description

Hello

we're running maven 3.6.0 builds in a docker container and we use Nexus OSS configured as proxy for Maven Central.

While running our builds using Gitlab CI, we're experiencing intermittent build failures because Maven cannot find artifacts in Nexus which we verified they are actually available.

Error example below:

20744 [main] [ERROR] Failed to execute goal on project EcotransitWSClient: Could not resolve dependencies for project it.sdb.ecotransit:EcotransitWSClient:jar:7.0.1-SNAPSHOT: Could not transfer artifact commons-beanutils:commons-beanutils:jar:1.9.3 from/to nexus (http://maven-repo.sdb.it:8081/repository/maven-public/): /builds/sdb/webportal/.m2/repository/commons-beanutils/commons-beanutils/1.9.3/commons-beanutils-1.9.3.jar.part (No such file or directory) -> [Help 1]

I attached the full maven build log and our Docker env settings.

We tried disabling the keep alive and also disabling the connection pooling but nothing seems to fix the issue.
