gradle conflicting transitive dependency not being included - gradle

Question

I have a dependency, my-project that uses two dependencies that use different versions of commons-lang3 but when I build my war artifact, commons-lang3 is not included in the artifact. What could be wrong?
My build.gradle looks like:
apply plugin: 'io.spring.dependency-management'
apply plugin: 'java'
apply plugin: 'maven-publish'
apply plugin: 'war'
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'io.spring.gradle:dependency-management-plugin:0.3.0.RELEASE'
}
}
compileJava {
sourceCompatibility = 1.7
targetCompatibility = 1.7
}
configurations.all {
exclude group: 'commons-logging'
}
repositories {
jcenter()
maven {
credentials {
username = "${artifactory_user}"
password = "${artifactory_password}"
}
url "myrepo.com"
}
}
dependencyManagement {
imports {
mavenBom 'io.spring.platform:platform-bom:1.1.2.RELEASE'
}
}
dependencies {
compile "my.project:my-project:1.0.0-SNAPSHOT"
// Spring Framework
compile 'org.springframework:spring-context'
compile 'org.springframework:spring-web'
compile 'org.springframework:spring-webmvc'
compile 'org.springframework.security:spring-security-config'
compile 'org.springframework.security:spring-security-web'
// Jackson
compile "com.fasterxml.jackson.core:jackson-annotations"
compile "com.fasterxml.jackson.core:jackson-core"
compile "com.fasterxml.jackson.core:jackson-databind"
// Logging
compile 'ch.qos.logback:logback-classic'
compile 'org.slf4j:slf4j-api'
runtime 'org.slf4j:jcl-over-slf4j'
runtime 'org.logback-extensions:logback-ext-loggly:0.1.2'
// Test
testCompile 'junit:junit'
testCompile 'org.mockito:mockito-core'
testCompile 'org.springframework:spring-test'
providedCompile 'javax.servlet:javax.servlet-api'
}
publishing {
publications {
mavenJava(MavenPublication) {
from components.web
}
}
repositories {
maven {
credentials {
username = "${artifactory_user}"
password = "${artifactory_password}"
}
if(project.version.endsWith('-SNAPSHOT')) {
url "myrepo.com/libs-snapshot-local"
} else {
url "myrepo.com/libs-release-local"
}
}
}
}
task wrapper(type: Wrapper) {
gradleVersion = '2.4'
}
EDIT Dependency diagram of my.project:my-project
my-project is a library project that my co-worker wrote that is dependent on two other library projects that contain commons-lang3. An example diagram would be
my.project:my-project:1.0.0-SNAPSHOT
+---my.project:my-dependency-1:1.0.0
| +---org.apache.commons:commons-lang3:3.4
+---my.project:my-dependency-2:1.0.0
+---org.apache.commons:commons-lang3:3.3.2

Answer 1

I updated the spring gradle dependency-management-plugin to 0.5.2.RELEASE and that fixed my problem.
