我的依赖关系文件和模块信息.java文件非常简单。

 模块Java9Gradle.main {
需要spring.boot; 
 
 
 $ b group'Java9Gradle'
 version'1.0-SNAPSHOT'
 
 apply plugin：'java'
 
 sourceCompatibility = 1.9 
 
存储库{
 mavenCentral（）
} 
 
依赖项{
 // https：// mvnrepository。 com / artifact / org.springframework.boot / spring-boot-starter 
编译组：'org.springframework.boot'，名称：'spring-boot-starter'，版本：'1.5.3.RELEASE'
 // https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-web 
编译组：'org.springframework.boot'，名称：'spring-boot- starter-web'，version：'1.5.3.RELEASE'
 testCompile group：'junit'，name：'junit'，version：'4.12'
} 
  

有人可以帮忙吗？

谢谢，

解决方案

根据拼图规格

不干扰 - Java编译器，虚拟机和运行时
系统必须确保包含相同名称
的包的模块不会相互干扰。如果两个不同的模块包含同名的
包，则从每个模块的角度来看，
该包中的所有类型和成员仅由该
模块定义。一个模块中的代码不能访问
包私有类型或其他模块中该包的成员。

在@Andy 此处的答案中，这被称为拆分包。因此，解决方案是将这些包解包并确保包含在您的模块中的包 jcl.over.slf4j 和 commons.logging


---

您可以分析两个依赖关系 spring -boot-starter：1.5.3.RELEASE 和 spring-boot-starter-web：1.5.3.RELEASE 以确保两个模块包含在您的项目中。

My dependencies file and the module-info.java file are very straight forward.

    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

Can someone please help??

解决方案

According to the Jigsaw specs

Non-interference — The Java compiler, virtual machine, and run-time system must ensure that modules that contain packages of the same name do not interfere with each other. If two distinct modules contain packages of the same name then, from the perspective of each module, all of the types and members in that package are defined only by that module. Code in that package in one module must not be able to access package-private types or members in that package in the other module.

This is referred to as split packages in the answer by @Andy here. The solution thereby is to unsplit these packages and make sure that the packages that are included from your modules jcl.over.slf4j and commons.logging are accessed via only one module.

---

You can analyze both dependencies spring-boot-starter:1.5.3.RELEASE and spring-boot-starter-web:1.5.3.RELEASE to make sure either of the two modules is included in your project.
