Eclipse - Maven - Dependencies not getting automatically reflected

Question

I have installed

• Java 1.7
• Eclipse Juno
• From Eclipse Market place have installed - Maven Integration for Eclipse WTP (a.k.a m2e-wtp), m2e-apt, Spring IDE, The Spring Tool Suite™ (STS)
• Have defined M2_HOME as directory where Maven is installed. PATH updated as %M2_HOME%/bin

I am working on Windows XP.

I am able to create a Maven project but when trying to add Dependencies (select pom.xml - Dependencies - Add) artifactId's "Enter groupId, artifactId or sha1 prefix or pattern" which are inputted are not getting displayed. Say if I input "springframework", it only reflect the jars that installed locally and don't search over the internet. Also if I check Maven Repositories (select by Windows - Show Views - Others - Maven - Maven Repositories), nothing is shown in Global Repositories - central (http://repo.maven.apache.org/maven2).

In case, if I manually put required artifactID in pom.xmland then update maven it downloads the required jars.

I am working on my home computer where I don't have any proxies and has set following in local m2 settings (C:\Documents and Settings\Sandy\.m2\Settings.xml)

Can you please advise, what setting I need to do so that inputted artifact's can be added using add Dependencies option?

Thanks in advance

Solution 1

Finally issue got resolved :) :)

Here what was done:

• Followed @khmarbaise, @SaifAsif, @Adrian comments :) Thanks for them I was able to understand the overlooked configurations
• Installed Eclipse Kepler (I was using Eclipse Juno) and Spring IDE from marketplace
• Maven Download setting as shown by @khmarbaise
• Copied global setting of maven (f:\maven\conf\settings.xml) to my local setting (C:\Documents and Settings\Sandy.m2). I didn't modified any thing in it.
• Windows - System environment variables were set
• M2_HOME - To the local installion (f:\Maven)
• M2 - %M2_HOME%\bin
• JAVA_HOME (already exist) - f:\java
• PATH - %M2%;%JAVA_HOME%\bin
• CLASSPATH - %JAVA_HOME%

At end I was able to see the dependencies automatically.

Thanks!

Also if I check Maven Repositories (select by Windows - Show Views - Others - Maven - Maven Repositories), nothing is shown in Global Repositories - central(http://repo.maven.apache.org/maven2).

It is most likely that your central Repository index might never have been updated. To resolve it , Go to Window > Show View > Other > type Maven in filter and select Maven Repositories. In Maven Repositories tab Expand Global Repositories, Right-click on central and Update Index.

The process will initially take about a few minutes depending on the network speed but once its done, the search box will start showing results when-ever you type in the name of any jar

The configuration for Eclipse can be found here:

The screen shot is from Mac OS but also on Windows you will find this under preferences -> Maven.

Please note, that this process could take more than just a "few" minutes ;)

[Saif Asif]

sometimes, yes ! I remember my initial update/re-index took about 7-10mins. Actually the size of the file ( the index file ) is approximately around 60MB ( if I remember correctly ).

[Adrian]

Ui, that's quite small. My indexed file is typically larger than 1GB. Maybe we should cleanup our internal Nexus ;)

[Saif Asif]

your talking about the nexus indexer ? I thought you meant the index file of mvn central. Thats 60MB. Oh and yeah the nexus index files usually count up in GB . You also don't cleanup your nexus? Join the club ;)

@SaifAsif - Any message on bar is shown? I Updated the Index and even after 10-15 mins nothing happened!!

[Sandeep]

@SaifAsif - Tried couple of times, but is not working. I even uninstalled all Maven and Spring IDE from Maketplace and re-installed it but it didn't helped! Any advise>

[Saif Asif]

@Sandeep Yes it should show a status bar showing something like downloading/updating maven index. And it should take a couple of minutes.

[Saif Asif]

Thats great. Don't forget to upvote and accept the answer :)
