问题描述

在更新Firefox之后，我将库的版本更改为更高版本.出现以下错误: [错误] commons-collections:commons-collections:3.2.2依赖关系的依赖收敛错误是:

[ERROR] +-net:serenity.pom.gradle:0.0.1-SNAPSHOT
[ERROR] +-net.serenity-bdd:serenity-core:1.1.29-rc.3
[ERROR] +-org.seleniumhq.selenium:htmlunit-driver:2.20
[ERROR] +-commons-collections:commons-collections:3.2.2
[ERROR] and
[ERROR] +-net:serenity.pom.gradle:0.0.1-SNAPSHOT

[ERROR] +-io.appium:java-client:3.3.0
[ERROR] +-commons-validator:commons-validator:1.4.1

[ERROR] and
[ERROR] +-net:serenity.pom.gradle:0.0.1-SNAPSHOT
[ERROR] +-net.serenity-bdd:serenity-core:1.1.29-rc.3
[ERROR] +-commons-collections:commons-collections:3.2.2
[ERROR] ]
[ERROR] -> [Help 1]

依赖树如下:

[INFO] +- net.serenity-bdd:serenity-core:jar:1.1.29-rc.3:test
[INFO] |  +- org.seleniumhq.selenium:htmlunit-driver:jar:2.20:test

[INFO] |  |     +- commons-beanutils:commons-beanutils:jar:1.8.3:test
[INFO] |  |     \- commons-digester:commons-digester:jar:1.8.1:test

如何解决这个问题? 我可以手动切换媒体库吗?

PS 这是我的pom.xml

解决方案

请参见 POM参考，排除:

排除项明确告诉Maven，您不希望包括作为该依赖项依赖项(即其传递性依赖项)的指定项目.

另请参见 Apache Maven Enforcer规则，依赖项收敛:

如果一个项目有两个依赖项A和B，都依赖于相同的工件C，那么，如果A依赖于C的不同版本，那么C的版本依赖于B的话，该规则将使构建失败. >

[...]

这将成功.

After updating Firefox I changed versions of libraries to higher ones. Following errors appeard: [ERROR] Dependency convergence error for commons-collections:commons-collections:3.2.2 paths to dependency are:

How to solve this problem? Can I manually switch the library?

解决方案

See POM Reference, Exclusions:

Exclusions explicitly tell Maven that you don't want to include the specified project that is a dependency of this dependency (in other words, its transitive dependency).

See also Apache Maven Enforcer Rules, Dependency Convergence:

If a project has two dependencies, A and B, both depending on the same artifact, C, this rule will fail the build if A depends on a different version of C then the version of C depended on by B.

[...]

And this will succeed.

      <groupId>org.slf4j</groupId>

      <version>1.6.1</version>

    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-nop</artifactId>
      <version>1.6.0</version>
      <exclusions>
        <exclusion>
          <groupId>org.slf4j</groupId>
          <artifactId>slf4j-api</artifactId>
