Question

我有一个完美的工作项目。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 jars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

[错误]无法在项目compass_app上执行目标：无法执行解决项目的依赖关系 com.XXXXX.services:compass_app:jar:1.0-SNAPSHOT：收集失败在org.codehaus.jackson中依赖dencies：jackson-mapper-asl：jar：1.5.3 - ＆gt; org.codehaus.jackson：jackson-core-asl：jar：1.9.13：无法读取 org.codehaus.jackson的工件描述符：jackson-core-asl：j r：1.9.13：无法转移神器 org.codehaus.jackson：jackson-core-asl：pom：1.9.13 from / to m-all （http://XXXX/archives/all)：无法传输文件： http://XXXX/archives/all/org/codehaus/jackson/jackson-core-asl/1.9.13/jackson-core-asl-1.9.13.pom。返回码为：500，ReasonPhrase：无法找到托管存储库 id的配置：npanXXXX-1.5.0-maestXXXX-33。 - ＆GT; [帮助1]

我担心的是，为什么版本1.9.13在我的项目中未指定任何内容时尝试下载

我的pom文件中只有一个杰克逊罐子的声明。
我尝试过做mvn -X clean install＆gt; install.txt。

以下跟踪可能会有所帮助。

[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>

例外是。

我担心的是为什么版本1.9.13尝试下载时我没有在我的项目中的任何地方指定它

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

可能有点transitive dependency。

在进行maven构建时，杰克逊依赖版本被覆盖了
