Cannot resolve dropwizard version 2.1.3-SNAPSHOT in maven project pom in Intellij

Using the following dependency entry in my pom:
<dependencies>
<dependency>
<groupId>io.dropwizard</groupId>
<artifactId>dropwizard-core</artifactId>
<version>${dropwizard.version}</version>
</dependency>
</dependencies>
Using an older dropwizard version works fine:
<properties>
<dropwizard.version>2.0.9</dropwizard.version>
</properties>
But using the most up to date version as listed on mvnrepository:
<dropwizard.version>2.1.2</dropwizard.version>
gives the following error:
Dependency 'io.dropwizard:dropwizard-core:2.1.2' not found
Additionally, using the recommended version in dropwizard's tutorial page does not work either:
<dropwizard.version>2.1.3-SNAPSHOT</dropwizard.version>
I have the following to pull snapshots in my pom:
<repositories>
<repository>
<id>nexus</id>
<name>nexus-snapshot</name>
<url>http://localhost:8081/repository/maven-snapshots/</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
<releases>
<enabled>false</enabled>
</releases>
</repository>
</repositories>
Update:
By deleting io/dropwizard from my ~/.m2/repository directory and invalidating caches & restarting, I was able to load dropwizard version 2.1.2. I am still unable to determine how to properly load the SNAPSHOT version. I don't know what repository settings to add to my pom file in order to correctly link to that dependency.

Maven: copy local jar to target dir

I want a local jar located in C:/myLibs/TDKLogging/TDKLogging-2.1.6.jar
to be copied to my target dir when generating the war, so I modified my pom as follows:
<repositories>
<repository>
<id>JBossNexus</id>
<name>JBoss Nexus Repository Manager</name>
<layout>default</layout>
<url>https://webgate.tdk.com/JBoss/nexus/content/groups/public</url>
</repository>
<repository>
<id>my-local-repo</id>
<url>file://C:/myLibs/</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>tdk.com.iot.log</groupId>
<artifactId>TDKLogging</artifactId>
<version>2.1.6</version>
<type>jar</type>
</dependency>
..
But I got this error
Could not find artifact tdk.com.iot.log:TDKLogging:jar:2.1.6 in tdkPublicRepository (https://webgate.tdk.com/JBoss/nexus/content/groups/public)
How to tell maven to search the artifact in a specific repo ???? Can a project work with more than 1 repo at the same time ???? because I only have 1 jar in the local repo, the others ones are stored in the public repo

you may have more than one repo specified.
<repositories>
<repository>
<id>Webgate repository</id>
<url>https://webgate.tdk.com/JBoss/nexus/content/groups/public/</url>
</repository>
<repository>
<id>JBoss repository</id>
<url>http://repository.jboss.org/nexus/content/groups/public/</url>
</repository>
<repository>
<id>java.net</id>
<url>https://maven.java.net/content/repositories/public/</url>
</repository>
</repositories>
What about your particular situation - you have to add your jar and pom to your local repository. You have to run few commands.

Maven doesn't find dependency

I added a dependency in maven for servlet as seen here, here and here
Maven doesn't find it :
dependency javax.servlet:javax.servlet-api:3.0.1 not found
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
I tried to add this, which doesn't work :
<repository>
<id>maven2</id>
<url>https://mvnrepository.com</url>
</repository>
or this:
<repository>
<id>maven2</id>
<url>http://repo1.maven.org/maven2/javax/servlet/javax.servlet-api/3.0.1/</url>
</repository>

First of all you need to verify if you have Internet connectivity and then you can try to purge and resolve the dependencies in the local Maven repository as there could be some corrupted package, you can try the following command to accomplish this:
mvn dependency:purge-local-repository
Take a look to Purging local repository dependencies for more information.

Use default repostiory:
<repositories>
<repository>
<id>central</id>
<name>Central Repository</name>
<url>http://repo.maven.apache.org/maven2</url>
<layout>default</layout>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
</repositories>
Don't do like this: http://repo1.maven.org/maven2/javax/servlet/javax.servlet-api/3.0.1/
Even you should remove all content of the tag <repositories> or <repository> and all things inside these, Maven will automatic use default configuration.

Artifact com.oracle.toplink:toplink:jar:10.1.3 not found

I am trying to create a spring 4 project from scratch and maven is unable to resolve the dependency of com.oracle.toplink:toplink:jar:10.1.3
The following are the repositories that I have set in the pom.xml
<repositories>
<repository>
<id>repo2.maven.org</id>
<name>repo2.maveng.org</name>

Questions:
Which repo should I add to make sure maven resolves this dependency?
Usually, how does one know which repo has a particular artifact belong to?
The error message I see is below. Does this error mean Maven did not try looking up for it in other repositories mentioned?
Could not find artifact com.oracle.toplink:toplink:jar:10.1.3 in repo2.maven.org (http://repo2.maven.org/maven2) -> [Help 1]

The is Oracle toplink - toplink-10.1.3 in maven's Central repository http://repo1.maven.org/maven2. So you just only need to add the dependency in pom.xml, not the repository.
<dependency>
<groupId>com.oracle.toplink</groupId>
<artifactId>toplink</artifactId>
<version>10.1.3</version>
</dependency>
Source:
http://mavenhub.com/mvn/central/com.oracle.toplink/toplink/10.1.3
http://mvnrepository.com/artifact/com.oracle.toplink/toplink/10.1.3

Jongo Maven Dependency causing problems

I am currently trying to use the Jongo project to connect to a remote MongoDB.
To do so, I added these dependencies to my project :
<dependencies>
<dependency>
<groupId>org.jongo</groupId>
<artifactId>jongo</artifactId>
<version>1.0</version>
</dependency>
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>2.6.5</version>
</dependency>
</dependencies>
I already had some troubles with the first dependency (jongo:1.0), since maven could not retreive this version (the latest maven knew was 0.4) : Intellij tells me Dependency "org.jongo:jongo:1.0" not found. Yet, the dependency can be found there
I managed to get it via Project Structure -> Librairies
The problem is that this dependency is now local, and anyone who clones this project must import this dependency manually, which is not suitable.
I am using Intellij IDEA 13.0

First, the Sonatype dependency version in the snapshots repository you had linked in your post is 1.1-SNAPSHOT and not 1.0.
It's not recommended to use 3rd party snapshots in your build
If however you insist, you need to add Sonatype snapshots repository to your maven build as follows:
<repository>
<id>sonatype-snapshots</id>
<name>sonatype-snapshots</name>
<url>https://oss.sonatype.org/content/repositories/snapshots/</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
EDIT
The 1.0 version resides in Sonatype releases repository:
<repository>
<id>sonatype-releases</id>
<name>sonatype-releases</name>
<url>https://oss.sonatype.org/content/repositories/releases/</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>

Jongo 1.0 is in maven central. There is no need for extra repository configuration in your pom.
