Multiple SLF4J Bindings problems when using gretty #367

Open perqin opened 7 years ago

perqin commented 7 years ago

I'm switching from Cargo to gretty and use the following build.gradle:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'org.akhikhl.gretty:gretty:+'
    }
}

apply plugin: 'java'
apply plugin: 'eclipse-wtp'
apply plugin: 'war'
apply plugin: 'org.akhikhl.gretty'

sourceCompatibility = 1.7

repositories {
    mavenCentral()
}

gretty {
    contextPath = '/'
    servletContainer = 'tomcat7'
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

And when executing task appRun, I get the following error:

:prepareInplaceWebAppFolder UP-TO-DATE
:createInplaceWebAppFolder UP-TO-DATE
:compileJava UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE

As it runs properly over Cargo, I am confusing why I got such error......

Maybe this can helps, https://stackoverflow.com/questions/21140646/abstractmethoderror-when-try-to-initialize-spring

You have multiple slf4j bindings in your classpath, as error messages show. You should select only one binding, then it should work.
