copied!<pre><code>Caused by: java.lang.NoSuchMethodError: org.slf4j.impl.StaticLoggerBinder.getSingleton()Lorg/slf4j/impl/StaticLoggerBinder; </code></pre> <p>This means that you have the class <code>StaticLoggerBinder</code> in your classpath. But the class of your classpath does not have the method <code>getSingleton()</code></p> <p>This usually happens when you have dependencies that both use the same transitive dependency. This means that 2 of your dependencies (or your app, and a transitive dependency) are both using SLF4J internally with different versions. But your app can only use a single version of the class at the same time so it has to choose (don't know the rules here... random?)</p> <p>To solve the problem, you usually need to do a <code>mvn dependency:tree</code> to see which are using different versions of SLF4J.</p> <p>The solution is often to use a maven dependency exclusion on the lowest version. Libraries like SLF4J tend to be retrocompatible which means newer versions keep adding more features. Sometimes, a method is removed and then you have to keep the old library version, and pray. If this doesn't work there are still some options, like <a href="https://code.google.com/p/jarjar/">JarJar</a></p> <p>But for logging libraries it's sometimes a bit different, so my explaination is for general purpose, but it's probable you do not use the right logging library dependencies because they have very special packagings which are not always easy to understand :)</p> <hr> <p>Check what I found for you:</p> <ul> <li><a href="https://github.com/qos-ch/slf4j/blob/SLF4J_1.5.5/slf4j-api/src/main/java/org/slf4j/impl/StaticLoggerBinder.java">https://github.com/qos-ch/slf4j/blob/SLF4J_1.5.5/slf4j-api/src/main/java/org/slf4j/impl/StaticLoggerBinder.java</a></li> <li><a href="https://github.com/qos-ch/slf4j/blob/SLF4J_1.5.6/slf4j-api/src/main/java/org/slf4j/impl/StaticLoggerBinder.java">https://github.com/qos-ch/slf4j/blob/SLF4J_1.5.6/slf4j-api/src/main/java/org/slf4j/impl/StaticLoggerBinder.java</a></li> </ul> <p>The <code>getSingleton()</code> method appeared at version 1.5.6, so it is very probable that you have a library that uses an SLF4J version older that 1.5.6 :) You just need to exclude it with a maven exclusion (and pray).</p> <hr> <p>Edit: you should try:</p> <pre><code><dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-bundle-jaxrs</artifactId> <version>2.2</version> <exclusions> <exclusion> <groupId>org.slf4j</groupId> <artifactId>slf4j-jdk14</artifactId> </exclusion> <exclusion> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> </exclusion> </exclusions> </dependency> </code></pre> <p>Better, if you have a multimodule maven project with a parent pom you can use this with maven dependencyManagement xml node.</p>
