how to properly configure gradle build to avoid including log4j and slf4j from the resulting jar?
<p>I'm having an issue with my spring-boot application: I'm able to run it within Eclipse, but unable to run the jar file (built with gradle).
I run the following command to build my project:</p>

<pre><code>gradle buid
</code></pre>

<p>The build is successful: </p>

<pre><code> gradle build
:compileJava UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:findMainClass
:jar
:bootRepackage
:assemble
:compileTestJava UP-TO-DATE
:processTestResources UP-TO-DATE
:testClasses UP-TO-DATE
:test UP-TO-DATE
:check UP-TO-DATE
:build

BUILD SUCCESSFUL

<p>This is a fragment of the resulting jar file:</p>

<pre><code>jar -tvf build/libs/springboot-receiver-api-0.1.0.jar | grep log

</code></pre>

<p>when I attempt to run this jar file, I get this error:</p>

<p>What can I do, to avoid this clash of logging libraries, and to be able to run my jar file stand-alone?</p>
