Hi.
I have problem with this Exception:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

I tried this solution: SLF4J Error Codes but that did not help.

I don’t have any dependencies.

Hi Marcin,

Does it take place in standard deployment to Tomcat done by Studio?

Hi Konstantin,

Yes, in standard deployment.

I found reason: I added dependency: mybatis-freemarker and this exception appeared.
I removed this dependency , run clean task, and remove all build directories and deploy directory, gradle cache but it did not help.

Only one solution what I found, is created a new project and copy sources from prev project.

For mybatis-freemarker I must have this in build.gradle file:


        compile('org.mybatis.scripting:mybatis-freemarker:1.1.1') {
            exclude(group: 'org.slf4j', module: 'slf4j-log4j12')
            exclude(group:'org.mybatis',module:'mybatis-spring')
            exclude(group:'org.freemarker',module:'freemarker')
        }

I don’t know why dependencies destroyed project even when they are removed?

Marcin
p.s. Sorry for my bad english.

> don’t know why dependencies destroyed project even when they are removed?

That’s very strange. Either Tomcat contained the jars or build.gradle had the dependency and brought the jars again. If you still have that broken project, please take a look into tomcat/shared/lib folder and into build.gradle.

Thanks.

Hi
I have similar problem in my project but didn’t see anything related to mybatis in the build.gradle. I tried to fix it using the code that Marcin used but no luck. Here is the exception -

Hi.

Do you have any foreign dependencies in build.gradle?
