Missing artifact com.sun.jdmk:jmxtools:jar:1.2.1

Question

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">

  <version>0.0.1-SNAPSHOT</version>
  <packaging>jar</packaging>

    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>

        <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.

Answer 1

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>
