java - 进行 Maven 构建时 Jackson 依赖版本被覆盖

Question

我有一个完美运行的项目。我能够成功构建和部署。昨天，作为开发的一部分，我必须在我的项目中为 Jackson jar 添加以下 Maven 依赖项，之后 mvn clean install 开始失败。

 <dependency>
       <groupId>org.codehaus.jackson</groupId>
       <artifactId>jackson-mapper-asl</artifactId>
       <version>1.5.3</version>
</dependency>
<dependency>
       <groupId>org.codehaus.jackson</groupId>
       <artifactId>jackson-core-asl</artifactId>
       <version>1.5.3</version>
</dependency>

我收到的错误消息是

[ERROR] Failed to execute goal on project compass_app: Could not resolve dependencies for project com.XXXXX.services:compass_app:jar:1.0-SNAPSHOT: Failed to collect depe dencies at org.codehaus.jackson:jackson-mapper-asl:jar:1.5.3 -> org.codehaus.jackson:jackson-core-asl:jar:1.9.13: Failed to read artifact descriptor for org.codehaus.jackson:jackson-core-asl:j r:1.9.13: Could not transfer artifact org.codehaus.jackson:jackson-core-asl:pom:1.9.13 from/to m-all (http://XXXX/archives/all): Failed to transfer file: http://XXXX/archives/all/org/codehaus/jackson/jackson-core-asl/1.9.13/jackson-core-asl-1.9.13.pom. Return code is: 500 , ReasonPhrase:Unable to find managed repository configuration for id:npanXXXX-1.5.0-maestXXXX-33. -> [Help 1]

我担心的是，当我没有在项目中的任何位置指定版本 1.9.13 时，为什么会尝试下载版本 1.9.13

1. 我的 pom 文件中只有一个 jackson jar 声明。
2. 我尝试过执行 mvn -X clean install > install.txt 。

以下跟踪片段可能会有所帮助。

[DEBUG] Configuration: <?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <artifact default-value="${project.artifact}"/>
  <attachedArtifacts default-value="${project.attachedArtifacts}"/>
  <createChecksum default-value="false">${createChecksum}</createChecksum>
  <localRepository>${localRepository}</localRepository>
  <packaging default-value="${project.packaging}"/>
  <pomFile default-value="${project.file}"/>
  <updateReleaseInfo default-value="false">${updateReleaseInfo}</updateReleaseInfo>
</configuration>

异常(exception)是。

Answer 1

My concern is why is the version 1.9.13 attempted for a download when I have not specified it anywhere in my project

请使用mvn dependency:tree(请参阅:documentation)，以便您能够跟踪加载此版本的原因。

这可能是transitive dependency .
