Maven构建错误“在[jackson-annotation，jackson-core，jackson-databind]中发现重复和不同的类”都是在2.10.0

Question

我将我的jackson-databind maven reference从2.9.9.3升级到2.10.0，以克服一些安全漏洞。为了克服一些实现问题，我还必须将jackson-core和jackson-annotation升级到2.10.0。现在我得到了一个maven副本搜索器，它提到了所有3个罐子。

我尝试使用maven资源库中提到的.prX版本。更改我的pom中引用的jar的顺序。

<properties>
    <fasterxml-jackson.version>2.10.0</fasterxml-jackson.version>
    <fasterxml-jackson-databind.version>2.10.0</fasterxml-jackson-databind.version>
        ...
</properties>

<dependencies>
    <dependency>
         <groupId>com.fasterxml.jackson.core</groupId>
         <artifactId>jackson-annotations</artifactId>
         <version>${fasterxml-jackson.version}</version>
    </dependency>
    <dependency>
         <groupId>com.fasterxml.jackson.core</groupId>
         <artifactId>jackson-core</artifactId>
         <version>${fasterxml-jackson.version}</version>
    </dependency>
    <dependency>
         <groupId>com.fasterxml.jackson.core</groupId>
         <artifactId>jackson-databind</artifactId>
         <version>${fasterxml-jackson-databind.version}</version>
    </dependency>
    ....

现在，我在构建时遇到了以下问题：

[WARNING] Found duplicate and different classes in [com.fasterxml.jackson.core:jackson-annotations:2.10.0, com.fasterxml.jackson.core:jackson-core:2.10.0, com.fasterxml.jackson.core:jackson-databind:2.10.0.pr3]:

[ERROR] Failed to execute goal org.basepom.maven:duplicate-finder-maven-plugin:1.2.1:check (default) on project my-project: Found duplicate classes/resources! -> [Help 1]

Answer 1

如果你不介意冲突的类：

<plugin>
  <groupId>com.ning.maven.plugins</groupId>
  <artifactId>duplicate-finder-maven-plugin</artifactId>
  <configuration>
    <failBuildInCaseOfConflict>false</failBuildInCaseOfConflict>
    ...
  </configuration>
</plugin>

但是，如果你想解决这个问题，你必须检查你的依赖项并忽略其中的一些：

<plugin>
  <groupId>com.ning.maven.plugins</groupId>
  <artifactId>duplicate-finder-maven-plugin</artifactId>
  <version>1.1.0</version>
  <configuration>
    <ignoredDependencies>
      <dependency>
        <groupId>xml-apis</groupId>
        <artifactId>xml-apis</artifactId>
        <version>1.3.02</version>
      </dependency>
      <dependency>
        <groupId>xml-apis</groupId>
        <artifactId>xml-apis</artifactId>
        <version>1.3.03</version>
      </dependency>
    </ignoredDependencies>
    ...
  </configuration>
</plugin>
