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"> <modelVersion>4.0.0</modelVersion> <groupId>mygroup</groupId>   <artifactId>Test_Maven_03</artifactId>   <version>0.0.1-SNAPSHOT</version>   <packaging>jar</packaging>    <name>Test_Maven_03</name>   <url>http://maven.apache.org</url>    <properties>     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>   </properties>    <dependencies>     <dependency>       <groupId>junit</groupId>       <artifactId>junit</artifactId>       <scope>test</scope>     </dependency>     <dependency>         <groupId>log4j</groupId>         <artifactId>log4j</artifactId>         <version>1.2.15</version>     </dependency>   </dependencies>   <dependencyManagement> <dependencies>     <dependency>         <groupId>junit</groupId>         <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>
