【Maven】Missing artifact com.sun:tools:jar:1.5.0

[size=medium]Eclipse maven has following error:
Missing artifact com.sun:tools:jar:1.5.0[/size]

Eclipse use "C:\windows\system32\javaw.exe" as default JVM, of course cant find tools.jar.

[size=medium]Solution I：[/size]
Modify eclipse.ini which in the eclipse.exe directory, add the following configuration:
[b][color=darkblue]-vm
D:\Program Files\Java\jdk1.6.0_37\bin\javaw.exe[/color][/b]

Note:
1. -vm cannot have a space behind;
2. the first line is parameter, and the second line is the value, need to separate.
3. This configuration is in the front of the file best.


[size=medium]Solution II:[/size]

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  	<java.home>D:\Program Files\Java\jdk1.6.0_37</java.home>

  <profiles>
     <profile>

  <dependencies>   
    <dependency>
        <groupId>com.sun</groupId>
        <artifactId>tools</artifactId>
        <version>1.5.0</version>
        <scope>system</scope>
        <systemPath>${java.home}/lib/tools.jar</systemPath>
    </dependency>
  </dependencies>

PS: here, <profiles> and <dependencies> must be sepreated, or it cant solve the problem.
