[jira] [Created] (LOG4J2-1876) Unreliable checking for runtime
dependencies
Mikael Ståldal created LOG4J2-1876:
--------------------------------------
Summary: Unreliable checking for runtime dependencies
Key: LOG4J2-1876
URL: https://issues.apache.org/jira/browse/LOG4J2-1876
Project: Log4j 2
Issue Type: Bug
Components: Core
Affects Versions: 2.8.2
Reporter: Mikael Ståldal
If I include this in Maven POM:
{code}
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.8.7</version>
<scope>runtime</scope>
<exclusions>
<exclusion>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
</exclusion>
</exclusions>
</dependency>
{code}
I get this printed on STDERR on startup:
{code}
