Maven 2-从传递依赖项版本定义依赖项版本 [英] Maven 2 - define dependency version from transitive dependency version
问题描述
我将用我的真实情况解释这个问题.
I'll explain the question with my real situation.
我使用logback 1.0.1进行日志记录，它包括SLF4J 1.6.4作为依赖项.我还将SLF4J API桥用于旧式日志记录API(java.util.logging，log4j和commons-logging)，它们不是显式的依赖项.这些还必须(最好是)版本1.6.4.
I use logback 1.0.1 for logging, and it includes SLF4J 1.6.4 as a dependency. I also use the SLF4J API bridges for legacy logging API's (java.util.logging, log4j and commons-logging), which are not explicit dependencies. These must also (preferrably) be version 1.6.4.
试图使我的pom.xml尽可能整洁且无错误，我想强制要求这些API桥与SLF4J的版本相同.我知道的唯一方法是使用1.6.4版在我的pom.xml中手动将它们定义为依赖项.如果我更新了logback，并且提高了所需的SLF4J版本，则需要记住将网桥API更改为正确的版本.
Trying to make my pom.xml as neat and error-free as possible, I'd like to enforce that these API bridges be the same version as SLF4J. The only way I know is to manually define them as dependencies in my pom.xml using version 1.6.4. If I ever update logback and the required SLF4J version is raised, I'd need to remember to change the bridge API's to the proper version.
我可以以某种方式将旧版API的版本与传递依赖项SLF4J的版本挂钩吗?
Can I somehow hook the legacy API's version to the version of the transitive dependency SLF4J?
当前pom.xml:
<properties>
<org.slf4j.version>1.6.4</org.slf4j.version>
</properties>
<dependencies>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.0.1</version>
<!-- requires SLF4J 1.6.4 -->
</dependency>
<!-- ... -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>log4j-over-slf4j</artifactId>
<version>${org.slf4j.version}</version>
<!-- here, how to bind this version value to SLF4J's version? -->
<scope>runtime</scope>
</dependency>
<!-- the other two bridge API's go here -->
</dependencies>
推荐答案
依赖性融合可能会为您提供帮助.谢谢@wemu！
Dependency Convergence may help you. Thank you @wemu!
我有一个相同吗?问题.
您可以克隆 https://gist.github.com/f35db1ac6dc8b6f45393.git
<dependencies>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.1.3</version>
<scope>runtime</scope> <!-- depends on slf4j-api:1.7.7 -->
</dependency>
<dependency>
<groupId>org.slf4j</groupId>

<dependency>

此时，一切正常.

现在让我们更改slf4j-api的版本.
Now let's change the slf4j-api's version.
$ mvn -Dunified.slf4j-api.version=1.7.13 -Dverbose=true dependency:tree verify
