Description

Maven Version 3.6.1

command : mvn -U -T 2C -DskipTests=true clean install -s settings.xml

We have several modules with same dependency and it is failing when two are downloading same dependency at the same time with below error. 

if we remove parallel flag it will go through. But the build will be very long.

Ideally it should wait and not fail?

[ERROR] Failed to execute goal on project content-model: Could not resolve dependencies for project com.gehc.ei.zfp:content-model:jar:6011.0.1.8270: Failed to collect dependencies at com.gehc.ei.zfp:ei-logging-service:jar:6011.0.1.8109 -> com.gehc.ei.zfp:atna-log-appender:jar:6011.0.1.8109: Failed to read artifact descriptor for com.gehc.ei.zfp:atna-log-appender:jar:6011.0.1.8109: Could not transfer artifact com.gehc.ei.zfp:atna-log-appender:pom:6011.0.1.8109 from/to central (xxxx[/artifactory/maven-zfp-all|: C:\Users\user\.m2\repository\com\gehc\ei\zfp\atna-log-appender\6011.0.1.8109\atna-log-appender-6011.0.1.8109.pom.part.lock (The process cannot access the file because it is being used by another process) -> [Help 1] 

Any idea why it is behaving this way?
