Description
If something (for example a Bamboo plugin) declares a dependency on bamboo-web 2.3-SNAPSHOT, Bamboo web will bring in conflicting versions of slf4j components:
\- com.atlassian.bamboo:atlassian-bamboo-web:jar:2.3-SNAPSHOT:compile
+- com.atlassian.bamboo:atlassian-bamboo-core:jar:2.3-SNAPSHOT:compile
| \- com.atlassian.bamboo:atlassian-bamboo-api:jar:2.3-SNAPSHOT:compile
| +- org.slf4j:slf4j-log4j12:jar:1.5.6:compile
| \- org.slf4j:jcl-over-slf4j:jar:1.5.6:compile
\- com.atlassian.profiling:atlassian-profiling:jar:1.8:compile
\- org.slf4j:slf4j-api:jar:1.4.3:compile
As you can see, 1.4.3 API is imported while the implementation is 1.5.6. This causes the following error when trying to run jwebunit tests:
java.lang.IllegalAccessError: tried to access field org.slf4j.impl.StaticLoggerBinder.SINGLETON from class org.slf4j.LoggerFactory at org.slf4j.LoggerFactory.<clinit>(LoggerFactory.java:60) at org.apache.commons.logging.impl.SLF4JLogFactory.getInstance(SLF4JLogFactory.java:155)
and is very strongly warned against by the slf4j FAQs.
Plugins depending on bamboo web can work around this issue by adding the following to their pom:
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.5.6</version>
</dependency>
</dependencies>
</dependencyManagement>
But really, this should be resolved at the bamboo web level.
