我正在尝试将我的项目从gradle构建转换为maven构建。我能够从maven生成war文件，但是maven中的某些依赖jar的版本与gradle的版本不同。
的build.gradle：
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath('org.springframework.boot:spring-boot-gradle-plugin:1.5.2.RELEASE')
classpath('org.apache.hive:hive-jdbc:2.0.0')
classpath('postgresql:postgresql:9.1-901-1.jdbc4')
classpath('org.apache.logging.log4j:log4j-core:2.8.2')
}
}
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
bootRepackage {
mainClass = 'com.rest.api.app'
}
apply plugin: 'war'
apply plugin: 'maven'
war {
baseName = 'app'
}
repositories {
mavenCentral()
}
configurations {
all*.exclude module: 'slf4j-log4j12'
all*.exclude module: 'log4j-slf4j-impl'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
dependencies {
compile('org.springframework.boot:spring-boot-starter-web'){
exclude module : 'spring-boot-starter-logging'
}
providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
compile('org.apache.lucene:lucene-snowball:3.0.3')
compile('org.apache.hive:hive-jdbc:2.0.0')
compile('postgresql:postgresql:9.1-901-1.jdbc4')
compile('com.fasterxml.jackson.dataformat:jackson-dataformat-yaml:2.8.8')
compile('com.fasterxml.jackson.core:jackson-databind:2.8.8.1')
compile('org.apache.logging.log4j:log4j-core:2.8.2'){
force=true
}
compile('org.apache.logging.log4j:log4j-api:2.8.2'){
force=true
}

}
task writeNewPom {
doLast {
pom {

}.writeTo("$buildDir/mavenpom.xml")
}
}

问题1：为什么上述罐子的版本不相同？
问题2：为什么使用Gradle构建的战争有＆＃39; cglib-2.2.1-v20090111.jar＆＃39;但不是在使用maven构建的战争中？
答案 0 :(得分：4)
如果依赖关系树中出现多个版本，则Maven和Gradle会遵循不同的规则来选择传递依赖关系的版本。 Maven通常使用最近的外观（来自树根的步数），而Gradle默认使用最高版本。
在Maven中，您可以使用DependencyManagement来修复冲突的传递依赖项的版本。
