java - Unable to run spark, phoenix/hbase with Spring Boot: Detected both log4j-over-slf4j.jar AND bound slf4j-log4j12.jar on the class path -


when try compile/build spring boot project spark/phoenix dependencies, says there's many slf4j's, , when try exclude package, throws above error.

how can them work together?

    buildscript {         ext {             springbootversion = '1.5.6.release'         }         repositories {             mavencentral()         }         dependencies {             classpath("org.springframework.boot:spring-boot-gradle-plugin:${springbootversion}")         }     }      apply plugin: 'java'     apply plugin: 'eclipse'     apply plugin: 'org.springframework.boot'      version = '0.0.1-snapshot'     sourcecompatibility = 1.8      repositories {         mavencentral()     }      //this doesn't work     configurations {         compile.exclude group:'ch.qos.logback'     }      dependencies {         compile('org.springframework.boot:spring-boot-starter')         /* excluding here didn't work */         compile('org.springframework.boot:spring-boot-starter-web')         compile('org.apache.spark:spark-sql_2.10:1.5.2')         compile('org.apache.spark:spark-core_2.10:1.5.2')         compile('org.apache.phoenix:phoenix-spark:4.7.0-hbase-1.1')         testcompile('org.springframework.boot:spring-boot-starter-test')     }
