SLF4J NoSuchMethodError on LocationAwareLogger
79,417
Solution 1
The javadocs for NoSuchMethodError say,
Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.
So this is probably being caused by incompatible versions of slf4j being loaded. Rather than looking at your classpath and guessing where classes are loaded, find where your class is loaded as described here.
Print out where org.slf4j.spi.LocationAwareLogger, org.apache.commons.logging.impl.SLF4JLocationAwareLog and org.slf4j.Marker are being loaded from.
Solution 2
I had the same error message, but the solution was different for me. I had to remove to following dependency from the maven pom:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jcl-over-slf4j</artifactId>
<version>1.6.1</version>
</dependency>
After that the error vanishes and everything worked for me.
Solution 3
We were facing the similar problem and it turned out we had 2 incompatible versions of slf4j jars in the classpath. The class path had the following 2 incompatible versions. After removing the lower versions from the classpath, the problem was fixed.
slf4j-api-1.6.1.jar
slf4j-log4j12-1.6.1.jar
slf4j-api-1.5.11.jar
slf4j-log4j12-1.5.11.jar
Solution 4
One Solution.
Verify on eclipse directory: configuration\org.eclipse.equinox.simpleconfigurator\bundles.info
slf4j no more one
Solution 5
do
mvn clean dependency:tree -DskipTests;
remove all the dependencies of "org.slf4j" except one (highest one") as
<dependency>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.6</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-jdk14</artifactId>
</exclusion>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>jcl-over-slf4j</artifactId>
</exclusion>
</exclusions>
</dependency>

This is a question that has been asked before, but unfortunately no solution seems to work for me. I am facing this exception (with abridged stack trace):
java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V at org.apache.commons.logging.impl.SLF4JLocationAwareLog.debug(SLF4JLocationAwareLog.java:133) at org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager$1.getConnection(ThreadSafeClientConnManager.java:221) at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:401) at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:820)This happens when compiling using a command line Maven and also when deploying to Tomcat. It works fine inside IntelliJ IDEA.
Usually I would expect this to be caused by multiple versions of the SLF4J library being in use. But the Maven dependency tree shows all slf4j libraries in a single version:
..$ mvn dependency:tree | grep slf4j [INFO] +- org.slf4j:slf4j-simple:jar:1.6.4:compile [INFO] | \- org.slf4j:slf4j-api:jar:1.6.4:compile [INFO] +- org.slf4j:slf4j-api:jar:1.6.4:compile [INFO] +- org.slf4j:jcl-over-slf4j:jar:1.6.4:compile [INFO] +- org.slf4j:slf4j-simple:jar:1.6.4:compileI even ensured that there is no other JAR in ~/.m2/repository
There are no references to commons-logging libraries either (I excluded them all as confirmed by the dependency tree.
How can I resolve this issue? I'm running out of ideas.

I tried to 'hg bisect' the problem, but going back weeks I could not find a version that works. Some of these are running in production systems, so it is not likely to be a code change that causes this problem.

Peter Becker over 12 yearsI should have thought about asking the class loader. It turns out auskey.abr.gov.au was the culprit: they dumped a copy of a 1.5.8 slf4j into /usr/java/packages/lib/ext/ when I installed their key 5 days ago. There's more scary stuff in there (log4j, bcmail, jaxb...) -- I'll need to set up a separate JRE. I wish slf4j would stop breaking binary compatibility, though.

Marty Pitt over 12 yearsJust hit exactly this problem after installing auskey! Thanks for the comment, @PeterBecker.

yasko about 5 yearsI added it as
provideddependency in my parent pom -
payne almost 4 yearsI'm able to import the classes mentioned in this answer (as in the IDE doesn't complain about not finding them), but when I try to run the code which is supposed to display where they are loaded from, I get a compilation error:package does not existandcannot find symbol. Yetslf4jis in my classpath, and only one version too. -
Peter Becker over 3 years@payne I would have used a clean JRE (it's been a while), but it was a problem different to yours. You may be having the dependency on the IDE's library set, but not the runtime classpath. It might need it's own question.

payne over 3 yearsIf it was there in the first place, there might have been a reason why?
