Maven failing to download jar dependencies

Question

I have a very simple default application that I've created to test my Eclipse Indigo/Maven v3.0.1 setup on my Windows 7 machine. The Hello World app runs fine from Eclipse.

Now from the command line I'm trying to test with mvn install.

At which point I see Maven download a large series of dependencies. For some reason though it will get stuck downloading one and will just stop part way through. It's not at the same point each time, but it's currently consistently the same jar file, eg...

http://repo1.maven.org/maven2/org/apache/maven/surefire/surefire-booter/2.5/surefire-booter-2.5.jar

If I download this file from a browser it works perfectly. Quite fast in fact. Now if I manually copy that downloaded file to the appropriate directory in my .m2 repository directory, the install continues to download dependencies until it hits another one at random which it stops at.

Here's my POM, although I'm not sure it'll help as it's so basic and seems to work fine with a mvn compile.

<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-4.0.0.xsd">   <modelVersion>4.0.0</modelVersion>    <groupId>com.kyeema</groupId>   <artifactId>QServer</artifactId>   <version>0.0.1-SNAPSHOT</version>   <packaging>jar</packaging>    <name>QServer</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>       <version>3.8.1</version>       <scope>test</scope>     </dependency>   </dependencies> </project> 

Here's some debug output referencing some dummy jar file?

OK guys, I had the same problem downloading a large file. We're all probably using the lightweight HTTP wagon. If you look at the docs:

http://maven.apache.org/wagon/wagon-providers/wagon-http-lightweight/

Known Limitation:

The main limitation is that you can't download data that doesn't fit entirely into memory.

So I increased the memory for Maven:

export MAVEN_OPTS="-Xmx1024m"

and voila, it works. (!!!!)
