D:/project/Java9Gradle/src/main/java/module-info.java
Error:(1, 1) java: module Java9Gradle.main reads package org.apache.commons.logging from both jcl.over.slf4j and commons.logging

Mi archivo de dependencias y el archivo module-info.java son muy sencillos.

module Java9Gradle.main {
    requires spring.boot;
}


group ''Java9Gradle''
version ''1.0-SNAPSHOT''

apply plugin: ''java''

sourceCompatibility = 1.9

repositories {
    mavenCentral()
}

dependencies {
    // https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter
    compile group: ''org.springframework.boot'', name: ''spring-boot-starter'', version: ''1.5.3.RELEASE''
    // https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-web
    compile group: ''org.springframework.boot'', name: ''spring-boot-starter-web'', version: ''1.5.3.RELEASE''
    testCompile group: ''junit'', name: ''junit'', version: ''4.12''
}

¿¿Puede ayudarme alguien, por favor??

Gracias,

Amar

Answer 1

¡Excluir la dependencia transitiva hizo que funcionara y ajustó module-info.java también!

compile("org.springframework.boot:spring-boot-starter:1.5.3.RELEASE") {
        exclude group: ''commons-logging'', module: ''commons-logging''
    }
    compile("org.springframework.boot:spring-boot-starter-web:1.5.3.RELEASE"){
        exclude group: ''commons-logging'', module: ''commons-logging''
    }

Answer 2

De acuerdo con las especificaciones de Jigsaw

No interferencia: el compilador de Java, la máquina virtual y el sistema de tiempo de ejecución deben garantizar que los módulos que contienen paquetes del mismo nombre no interfieran entre sí. Si dos módulos distintos contienen paquetes del mismo nombre, entonces, desde la perspectiva de cada módulo, todos los tipos y miembros de ese paquete están definidos solo por ese módulo. El código en ese paquete en un módulo no debe poder acceder a los tipos o miembros del paquete privado en ese paquete en el otro módulo.

Esto se conoce como paquetes divididos en la respuesta de @Andy aquí . La solución es, por lo tanto, desvincular estos paquetes y asegurarse de que los paquetes que se incluyen desde los módulos jcl.over.slf4j y commons.logging se commons.logging a través de un solo módulo.

Puede analizar ambas dependencias spring-boot-starter:1.5.3.RELEASE y spring-boot-starter-web:1.5.3.RELEASE para asegurarse de que cualquiera de los dos módulos esté incluido en su proyecto.
