Could not find org.springframework.boot:spring-boot-starter-log4j

Question

I am trying to integrate the apache log4j in my Spring boot application. Here is my build.gradle file:

build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.4.3.RELEASE")
        classpath 'mysql:mysql-connector-java:5.1.34'
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'

jar {
    baseName = 'spring-boot-sample'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    // tag::jetty[]
    compile("org.springframework.boot:spring-boot-starter-web") {
        exclude module: 'spring-boot-starter-tomcat'
        exclude module: 'spring-boot-starter-logging'
    }
    compile("org.springframework.boot:spring-boot-starter-jetty")
    // end::jetty[]
    // tag::actuator[]
    compile("org.springframework.boot:spring-boot-starter-actuator")
    // end::actuator[]
    compile("org.springframework.boot:spring-boot-starter-log4j")
    compile("org.springframework.boot:spring-boot-starter-data-jpa")
    compile("mysql:mysql-connector-java:5.1.34")

    testCompile("junit:junit")

    testCompile("org.springframework.boot:spring-boot-starter-test")
}

Whenever I tried to build my project I am getting following build failure. I think following repos are not available:

https://repo1.maven.org/maven2/org/springframework/boot/spring-boot-starter-log4j//spring-boot-starter-log4j-.pom
https://repo1.maven.org/maven2/org/springframework/boot/spring-boot-starter-log4j//spring-boot-starter-log4j-.jar

Here is the complete build output with full stack trace exception:

BUILD FAILED

The last option I am guessing to fix this is to place the log4j library in bin location (the worst possible way) and provide that in .classpath Is there any better way??

Answer 1

log4j is EOL so it has been removed from Spring Boot as of Spring Boot 1.4. If you want to use log4j, use org.springframework.boot:spring-boot-starter-log4j2
