缺少的工件com.sun.jdmk：jmxtools：jar：1.2.1 [英] Missing artifact com.sun.jdmk:jmxtools:jar:1.2.1

问题描述

我已经从Eclipse Indigo中的maven-achetype-quickstart创建了简单的项目，然后我去了pom.xml gui编辑器和依赖关系选项卡添加依赖关系 log4j 通过搜索适当的对话。现在我的pom.xml看起来像

 < project xmlns =http://maven.apache.org/POM/4.0 .0xmlns：xsi =http://www.w3.org/2001/XMLSchema-instance
 xsi：schemaLocation =http://maven.apache.org/POM/4.0.0 http： //maven.apache.org xsd / maven-.0.0.xsd>

Eclipse说我的POM有很多问题，如

缺少的工件javax.jms：jms：jar：1.1 pom.xml / Test_Maven_03第2行Maven依赖关系问题

这是什么意思，以及如何查看自动的maven功能jar下载

编辑1
如果我选择log4j 1.2.16而不是1.2.15，我会收到另一个错误： Missing artifact log4j：log4j：bundle：1.2.16 。所以我看不到任何自动的jar管理。

解决方案

如果我记得正确，它不会被包含在许可证问题上。如果您不需要jms功能，可以从log4j依赖关系中排除jms：

 < dependency> 
< groupId> log4j< / groupId> 
< artifactId> log4j< / artifactId> 
< version> 1.2.15< / version> 
<排除> 
< exclude> 
< groupId> com.sun.jmx< / groupId> 
< artifactId> jmxri< / artifactId> 
< / exclusion> 
< exclude> 
< groupId> com.sun.jdmk< / groupId> 
< artifactId> jmxtools< / artifactId> 
< / exclusion> 
< exclude> 
< groupId> javax.jms< / groupId> 
< artifactId> jms< / artifactId> 
< / exclusion> 
< / exclusions> 
< / dependency> 
  

I have created simple project from maven-achetype-quickstart under Eclipse Indigo, then I went to pom.xml gui editor and in dependencies tab added dependency log4j by search in appropriate dialog. Now my pom.xml looks like

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org xsd/maven-.0.0.xsd">

        <artifactId>junit</artifactId>
        <version>3.8.1</version>
    </dependency>
</dependencies>
  </dependencyManagement>
</project>

Eclipse says my POM have many problems like

Missing artifact javax.jms:jms:jar:1.1 pom.xml /Test_Maven_03 line 2 Maven Dependency Problem

What does it mean and how to see maven feature of automatic jar downloading.

EDIT 1 If I select log4j 1.2.16 instead of 1.2.15, I get another error: Missing artifact log4j:log4j:bundle:1.2.16. So I see no automatic jar management at all.

解决方案

It's not included anymore due to licensing issues if I remember correctly. If you don't need jms functionality you can exclude jms from log4j dependency:

<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.15</version>
<exclusions>
    <exclusion>
        <groupId>com.sun.jmx</groupId>
        <artifactId>jmxri</artifactId>
    </exclusion>
    <exclusion>
        <groupId>com.sun.jdmk</groupId>
        <artifactId>jmxtools</artifactId>
    </exclusion>
    <exclusion>
            <groupId>javax.jms</groupId>
            <artifactId>jms</artifactId>
    </exclusion>
</exclusions>
</dependency>
