Description
I have a maven build for which logging during tests used to work.
Snippets from pom.xml:
<properties>
...
<slf4j.version>[1.7,1.8)</slf4j.version>
...

<dependencies>
<dependency>

Dependency tree snippet:
[WARNING] The artifact org.slf4j:slf4j-log4j12:jar:1.7.34 has been relocated to org.slf4j:slf4j-reload4j:jar:1.7.34 ... [INFO] +- org.slf4j:slf4j-api:jar:1.8.0-beta4:compile [INFO] +- org.slf4j:slf4j-reload4j:jar:1.7.34:test [INFO] | \- ch.qos.reload4j:reload4j:jar:1.2.18.3:test
Nothing has changed in my configuration, but after the 1.7.34 release, logging during tests no longer works and instead I see this:
[INFO] ------------------------------------------------------- [INFO] T E S T S [INFO] ------------------------------------------------------- [INFO] Running TestSuite SLF4J: No SLF4J providers were found. SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#noProviders for further details. SLF4J: Class path contains SLF4J bindings targeting slf4j-api versions prior to 1.8. SLF4J: Ignoring binding found at [jar:file:/Users/archie/.m2/repository/org/slf4j/slf4j-reload4j/1.7.34/slf4j-reload4j-1.7.34.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http://www.slf4j.org/codes.html#ignoredBindings for an explanation.
Is this backward-incompatibility expected?
FYI I was able to workaround the issue with these changes:
- <slf4j.version>[1.7,1.8)</slf4j.version>
+ <slf4j.version>1.7.34</slf4j.version>
...
- <artifactId>slf4j-log4j12</artifactId>
+ <artifactId>slf4j-reload4j</artifactId>
