Maven：如何覆盖由库添加的依赖关系 [英] Maven: how to override the dependency added by a library

问题描述

这是我的一般问题：

我的项目P依赖于A，它取决于依赖于D.的版本1.0.1的C。 >

D的版本1.0.1有问题，我想强制使用另一个模块。我不知道如何在我的项目的POM中声明这一点，因为我没有直接添加对D的依赖。这是C声明对D的依赖。

重要提示：在这种情况下，不仅版本被更改，而且组&神器也是。因此，这不仅仅是覆盖依赖关系的版本，而是排除模块并包括另一个模块。

在具体情况下，D是Stax，其1.0.1具有错误。根据bug的说明，通过用stax-api-1.0-2（maven GroupId = javax.xml.stream）替换stax-api-1.0.1（maven GroupId = stax）来解决问题，所以我'/ />

因此，D = stax：stax-api：jar：1.0.1和C = org.apache.xmlbeans：xmlbeans：jar：2.3 .0

我正在使用maven 2.0.9，以防万一重要。

输出mvn依赖关系：树

  mvn依赖：tree 
 [..snip ..]

 <在我的项目的POM中，我对A有以下依赖：

<依赖关系> 
< groupId> org.apache.poi< / groupId>

提前感谢

解决方案

只需指定当前pom中的版本。

强制版本

版本将如果在当前POM中声明具有特定版本，则始终都将获得荣誉 - 但是，应该注意的是，如果它本身依赖于使用传递依赖关系，这也将影响下游的其他pom。

Here's my generic problem:

My project P depends on A which depends on B which depends on C which depends on version 1.0.1 of D.

There's a problem with version 1.0.1 of D and I want to force the use of another module. I don't know how to declare this in my project's POMs since I haven't added a dependency on D directly. It's C which declared the dependency on D.

Important: In this case, not only the version is changed, but the group & artifact as well. So it's not just a matter of overriding the version of the dependency, but rather, of excluding a module and including another one.

In the concrete case, D is StAX whose 1.0.1 has a bug. According to the notes in the bug, "the problems were solved by replacing the stax-api-1.0.1 (maven GroupId = stax) by stax-api-1.0-2 (maven GroupId = javax.xml.stream)" so I'm trying just that.

Thus, D = stax:stax-api:jar:1.0.1 and C = org.apache.xmlbeans:xmlbeans:jar:2.3.0

I'm using maven 2.0.9 in case it matters.

Output of mvn dependency:tree"

mvn dependency:tree
[..snip..]
[INFO] +- org.apache.poi:poi-ooxml:jar:3.6:compile
[INFO] |  +- org.apache.poi:poi-ooxml-schemas:jar:3.6:compile
[INFO] |  |  +- org.apache.xmlbeans:xmlbeans:jar:2.3.0:compile
[INFO] |  |  |  \- stax:stax-api:jar:1.0.1:compile

In my project's POM I have the following dependency on "A":

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>3.6</version>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>3.6</version>
</dependency>

Thanks in advance.

解决方案

Simply specify the version in your current pom. The version specified here will override other.

Forcing a version
A version will always be honoured if it is declared in the current POM with a particular version - however, it should be noted that this will also affect other poms downstream if it is itself depended on using transitive dependencies.
