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 

phụ thuộc tập tin của tôi và tập tin module-info.java rất thẳng về phía trước.

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' 
} 

Ai đó có thể vui lòng trợ giúp ??

Cảm ơn,

Amar

Answer 1

Loại trừ sự phụ thuộc bắc cầu làm cho nó hoạt động và điều chỉnh module-info.java quá !!!

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

Theo Jigsaw specs

Không can thiệp - Trình biên dịch Java, máy ảo, và thời gian chạy hệ thống phải đảm bảo rằng các module có chứa các gói của cùng một tên không ảnh hưởng lẫn nhau. Nếu hai mô-đun riêng biệt chứa các gói có cùng tên thì, từ góc nhìn của từng mô-đun, tất cả các loại và thành viên trong gói đó chỉ được xác định bởi mô-đun đó. Mã trong gói đó trong một mô-đun không được truy cập các loại gói riêng tư hoặc thành viên trong gói đó trong mô-đun khác.

này được gọi là gói chia trong câu trả lời của @Andy here. Giải pháp do đó là để hủy các gói này và đảm bảo rằng các gói được bao gồm trong các mô-đun của bạn jcl.over.slf4j và commons.logging chỉ được truy cập thông qua một mô-đun.

Bạn có thể phân tích tất cả phụ thuộc spring-boot-starter:1.5.3.RELEASE và spring-boot-starter-web:1.5.3.RELEASE để đảm bảo một trong hai module được bao gồm trong dự án của bạn.
