I am new to spring boot and gradle. I am creating a spring boot application and want to use JDBC Template connection. My build.gradle is : 

buildscript {
    ext {
        springBootVersion = '1.5.2.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}


apply plugin: 'java'
apply plugin: 'eclipse-wtp'
apply plugin: 'org.springframework.boot'

sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    jcenter()
}

dependencies {
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-web', version: '1.5.2.RELEASE'
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-security', version: '1.5.2.RELEASE'

    compile project(':supplier-commons')
    runtime project(':supplier-commons')

    compile 'org.springframework:spring-context:4.2.6.RELEASE'
    compile 'org.springframework:spring-webmvc:4.2.6.RELEASE'
    compile 'org.springframework.data:spring-data-jpa:1.10.1.RELEASE'
    compile group: 'mysql', name: 'mysql-connector-java', version: '5.1.6'
    compile group: 'org.apache.logging.log4j', name: 'log4j-api', version: '2.7'
    compile group: 'org.apache.logging.log4j', name: 'log4j-core', version: '2.7'
    compile group: 'com.typesafe.akka', name: 'akka-actor_2.11', version: '2.4.1'
    compile 'io.jsonwebtoken:jjwt:0.7.0'
    compile group: 'javax.mail', name: 'mail', version: '1.4'
    compile group: 'freemarker', name: 'freemarker', version: '2.3.9'
    compile group: 'org.springframework.security', name: 'spring-security-crypto', version: '4.2.2.RELEASE'
    compile group: 'org.apache.commons', name: 'commons-email', version: '1.4'
    compile group: 'com.thoughtworks.xstream', name: 'xstream', version: '1.4.9'
    compile group: 'org.jmockit', name: 'jmockit', version: '1.8'
    compile 'io.jsonwebtoken:jjwt:0.7.0'
    compile group: 'com.ning', name: 'async-http-client', version: '1.9.40'
    compile group: 'org.mockito', name: 'mockito-all', version: '1.8.4'
    compile group: 'io.reactivex.rxjava2', name: 'rxjava', version: '2.0.7'

    compile('org.springframework.boot:spring-boot-starter-jdbc'){
        exclude module : 'spring-boot-starter-logging'
        exclude module: "logback-classic"
    }
    runtime('org.springframework.boot:spring-boot-devtools')
    compileOnly('org.springframework.boot:spring-boot-configuration-processor')

    testCompile 'junit:junit:4.12'

}

springBoot {
    executable = true
}

eclipse {

  wtp {
    facet {
        facet name: 'jst.web', version: '2.4'
    }

    component {
      contextPath = 'aggregator-api'
    }

  }
}

When I run the application, I get following error :

But when I remove 

compile('org.springframework.boot:spring-boot-starter-jdbc'){
        exclude module : 'spring-boot-starter-logging'
        exclude module: "logback-classic"
    }

I don't get any error but than I can't use jdbc connection.

Any solution?

For starters cleanup your build, you are trying to be too smart in there. Spring Boot has a lot of starters which you are including but also trying to bypass. 

dependencies {
    compile project(':supplier-commons')

    compile ('org.springframework.boot:spring-boot-starter') {
      exclude module : 'spring-boot-starter-logging'
    }
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-web'
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-freemarker'
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-mail'
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-security'
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-jdbc'
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-data-jpa'
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-log4j2'

    compile group: 'mysql', name: 'mysql-connector-java'
    compile group: 'com.typesafe.akka', name: 'akka-actor_2.11', version: '2.4.1'
    compile group: 'org.apache.commons', name: 'commons-email', version: '1.4'
    compile group: 'com.thoughtworks.xstream', name: 'xstream', version: '1.4.9'
    compile 'io.jsonwebtoken:jjwt:0.7.0'
    compile group: 'com.ning', name: 'async-http-client', version: '1.9.40'
    compile group: 'io.reactivex.rxjava2', name: 'rxjava', version: '2.0.7'

    testCompile group: 'org.jmockit', name: 'jmockit', version: '1.8'
    testCompile group: 'org.springframework.boot', name: 'spring-boot-starter-test'

    runtime('org.springframework.boot:spring-boot-devtools')
    compileOnly('org.springframework.boot:spring-boot-configuration-processor')
}

Something like that. This will pull in all the versions as defined by Spring Boot (notice a lot of the dependencies don't specify a version) and for the technologies you had declared you want to use the starters (so that you get the Spring Boot managed version).
