Missing artifact maven - java

I have the dependency
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>com.springsource.javax.servlet</artifactId>
<version>2.5.0</version>
</dependency>
in my pom file but it shows error saying.
Missing artifact javax.servlet:com.springsource.javax.servlet:jar:2.5.0
The below are the repositories that i used in my pom file
<repositories>
<repository>
<id>com.springsource.repository.bundles.release</id>
<name>SpringSource Enterprise Bundle Repository - SpringSource Bundle
Releases
</name>
<url>http://repository.springsource.com/maven/bundles/release</url>
</repository>
<repository>
<id>com.springsource.repository.bundles.external</id>
<name>SpringSource Enterprise Bundle Repository - External Bundle
Releases

<url>http://repository.springsource.com/maven/bundles/external</url>
</repository>
<repository>

<name>Java.net Repository for Maven</name>
<url>http://download.java.net/maven/2/</url>
<layout>default</layout>
</repository>
</repositories>

I do not know what happened but the m2 got screwed up as it created many m2 subfolders in m2. when i changed it. The Error was resolved, thanks for the quick reply guys.

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.

The best way to get rid from SNAPSHOT version in the dependency

I want to use dependency from the Cloudera Maven repository:
Extract from my pom.xml:
<repositories>
<repository>
<id>cloudera</id>
<url>https://repository.cloudera.com/cloudera/cloudera-repos/</url>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-core_2.10</artifactId>
<version>0.9.0-cdh4.6.0</version>
</dependency>
It depends on parent "spark-parent" that referenced to parent with SNAPSHOT version.
Extract from spark-parent pom.xml (https://repository.cloudera.com/artifactory/cloudera-repos/org/apache/spark/spark-parent/0.9.0-cdh4.6.0/):
<parent>
<groupId>com.cloudera.cdh</groupId>
<artifactId>cdh-root</artifactId>
<version>4.6.0-SNAPSHOT</version>
</parent>
<groupId>org.apache.spark</groupId>
<artifactId>spark-parent</artifactId>
<version>0.9.0-cdh4.6.0</version>
When I run simple "mvn clean package" I have the error that this SNAPSHOT artifact cannot be found.
What is the simplest way to solve this? A solution must be a change in pom.xml or in the build command.
Thanks.
The Cloudera Maven repository doesn't have the artifact com.cloudera.cdh:cdh-root:pom:4.6.0-SNAPSHOT, therefore you won't be able to build your project using it.
However, you can use the Spring cache of this repository: http://repo.spring.io/cloudera-cache. It contains the missing artifacts. You will also have to enable snapshot dependencies inside your repository:
<repositories>
<repository>
<id>cloudera-cache</id>
<url>http://repo.spring.io/cloudera-cache/</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
</repositories>

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

The following are the repositories that I have set in the pom.xml

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

How to add Spring to new Java Project in Eclipse?

I have Eclipse with m2 plugin and want to make new project with Spring.
In maven central repo are only Spring 1.x and Spring 2.x versions and adding http://maven.springframework.org/milestone to pom.xml don't change anything.
I the central repository there are also the latest final Spring artifacts (3.0.5.RELEASE).
E.g. http://repo1.maven.org/maven2/org/springframework/spring-beans/3.0.5.RELEASE
If you need milestones for 3.1 you should add repository definition to your pom.xml as follows:
<repository>
<id>spring-maven-milestone</id>
<name>Springframework Maven Milestone Repository</name>
<url>http://maven.springframework.org/milestone</url>
</repository>
And then you can define the dependency:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>3.1.0.M2</version>
</dependency>
There is also repository containing snapshots (nightly):
<repository>
<id>spring-maven-snapshot</id>
<snapshots><enabled>true</enabled></snapshots>
<name>Springframework Maven SNAPSHOT Repository</name>
<url>http://maven.springframework.org/snapshot</url>
</repository>
Seems like you want to use springs own repositories, but you need to add them in your settings.xml file (~/.m2/settings.xml), not in the pom.xml in your project.
<repository>
<id>repository.springframework.maven.release</id>
<name>Spring Framework Maven Release Repository</name>
<url>http://maven.springframework.org/release</url>
</repository>
<repository>
<id>repository.springframework.maven.milestone</id>
<name>Spring Framework Maven Milestone Repository</name>
<url>http://maven.springframework.org/milestone</url>
</repository>
<repository>
<id>repository.springframework.maven.snapshot</id>
<name>Spring Framework Maven Snapshot Repository</name>
<url>http://maven.springframework.org/snapshot</url>
</repository>
