Filipp Gunbin updated LOG4J2-2640:
----------------------------------
Summary: Circular dependency in log4j-core pom.xml (was: Circular
dependency in pom.xml)
> Circular dependency in log4j-core pom.xml
> -----------------------------------------
>
> Key: LOG4J2-2640
> URL: https://issues.apache.org/jira/browse/LOG4J2-2640
> Project: Log4j 2
> Issue Type: Bug
> Reporter: Filipp Gunbin
> Priority: Major
>
> Master fails to build unless current log4j-core version is already present in
> local maven repo:
> {quote}[ERROR] Failed to execute goal on project log4j-core: Could not
> resolve dependencies for project
> org.apache.logging.log4j:log4j-core:jar:3.0.0-SNAPSHOT: Could not find
> artifact org.apache.logging.log4j:log4j-core:jar:3.0.0-SNAPSHOT, try
> downloading from https://logging.apache.org/log4j/2.x/download.html -> [Help
> 1]
> {quote}
> This is because log4j-core has this dependency, which itself references
> log4j-core (with a defined version which gets correctly overriden by
> 3.0.0-SNAPSHOT).

> <artifactId>log4j2-custom-layout</artifactId>

> <scope>test</scope>

> Simplest fix is to add exclusion:
> {{diff --git a/log4j-core/pom.xml b/log4j-core/pom.xml
