Rather than "excluding" the dependency, you rather might add a dependency
management section to your application POM file to ensure that only a
single version of the SLF4J dependencies (and in particular, the
slf4j-log4j12 bridge) is present. For example...
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
*<version>1.7.7</version>*
</dependency>
</dependencies>
</dependencyManagement>
The version is based on the version called out in the
dependency-versions.properties
<https://github.com/apache/incubator-geode/blob/rel/v1.0.0-incubating.M2/gradle/dependency-versions.properties#L86>
[1]
file.
To my understanding, *Apache Geode* at version *1.0.0-incubating.M2* had
properly resolved all dependencies and cleaned up the dependency graph/tree
so that only a single version of any dependency is present. Are you using
SLF4J in your application and possibly pulling in a different version?
Either way, no matter, the "dependencyManagement" section will properly
constrain the SLF4J dependencies. You can declare any other possibly
conflicting dependencies in the dependencyManagement section of your POM
file as well.
Hope this helps!
