Is there a way to use multiple maven dependencies for one maven project in Eclipse?

Question

I am developing a Bukkit plugin with the M2E plugin in Eclipse. I have a problem where the maven dependency (Bukkit 1.5.2 R1.0) is in two different locations depending on whether I am at school or not. At home the file tree is in my dropbox with the maven repo at C:/users/canon/.m2/repository/org/bukkit/bukkit-1.5.2-R1.0 but at school it is located at C:/users/nmeyer/.m2/repository/org/bukkit/bukkit-1.5.2-R1.0. I have been able to recreate the project with maven such that the maven repository is in the correct place on only one computer at a time, but not both at once. Is there a way that I can tell Maven to look in both these file locations for the maven repository so I do not have to keep identical versions of the same project configured for one or the other locations only?

Additional Note: whichever file path I create the maven project with will work and display correctly with the bukkit-1.5.2-R1.0 jar file tree correctly displayed under maven dependencies, but it will not work on a computer in the other location (home vs school).

Clarification: The Maven repository is defined in my pom.xml but i don't see where to find the maven repo path. I've attached my pom.xml because the format of it seems to be a little different than the posted possible answers took into account:

Maybe you can create the directory from school in your home computer so it is the same path. Or you try to (sym)link that maybe. — xdevs23, Apr 11 '16 at 18:41
Dont sync the .classpath file between your computers, this contains computer local settings. — Ferrybig, Apr 11 '16 at 20:30

For Maven, you don't need to hard-code paths. You can use:

${user.home}

For example,

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      https://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository>${user.home}/.m2/repository</localRepository>
  <interactiveMode>true</interactiveMode>
  <usePluginRegistry>false</usePluginRegistry>
  <offline>false</offline>
  ...
</settings>

Review the maven settings reference for more info: https://maven.apache.org/settings.html

Your import, then, would look something like this:

<plugin>
    <groupId>org.bukkit</groupId>
    <artifactId>bukkit-1.5.2-R1.0</artifactId>
</plugin>

I figured out what the problem is, and it's so stupid that i didn't even think of it originally. Turns out that my school blocks bukkit.org as "games" and since school computer Eclipse hasn't had a chance to connect to that repository from the school computer since the repo http://repo.bukkit.org/content/groups/public/ was inaccessable.
