i am trying to build my project with maven v3.0.5 and jdk 1.7. snippets of my pom xml looks like the following.
<properties>
<sqoop.version>1.4.4</sqoop.version>
</properties>
<dependencies>
<dependency>
<groupId>org.apache.sqoop</groupId>
<artifactId>sqoop</artifactId>
<version>${sqoop.version}</version>
</dependency>
</dependencies>
when i run "mvn clean package" i see the following error:
Could not find artifact org.apache.sqoop:sqoop:jar:1.4.4 in central (http://repo.maven.apache.org/maven2)
usually and typically, i go to mvnrepository.com, and search for artifacts, and whatever artifacts i can find there, i have always been able to simply reference them in my pom.xml. according to this link, http://mvnrepository.com/artifact/org.apache.sqoop/sqoop/1.4.4, this artifact should exist?
i can't really browse http://repo.maven.apache.org/maven2.
Browsing for this directory has been disabled.
View this directory's contents on http://search.maven.org instead.
so i decided to use the search site for sqoop.
http://search.maven.org/#search%7Cga%7C1%7Csqoop
it seems to me that this artifact exists, but somehow, i can't access it. any ideas on what i'm doing wrong?
EDIT -
The Sqoop JAR varies based on what version of Hadoop you're using.
If you want to build against some Hadoop 0.23.x variant, what you need is the following:
<dependency>
<groupId>org.apache.sqoop</groupId>
<artifactId>sqoop</artifactId>
<version>1.4.4</version>
<classifier>hadoop23</classifier>
</dependency>
You will be able to see what classifiers are available using Eclipse. Right-click pom.xml, Maven --> Add Dependency. Type 'sqoop' in the search box, then expand the collapsed menu for org.apache.sqoop and note the options, hadoop23, hadoop100, etc.

I am not able to find any hint about the issue that I am facing and hence posting my question here. Please apologize if it is something silly.
I have some working experience in selenium webdriver. However in my new project, I was asked to use an existing Selenium framework.
In the pom.xml, I am seeing the below dependency (I have edited xxx to avoid displaying the company name)
<dependencies>
<dependency>
<groupId>com.xxxqa.selenium</groupId>
<artifactId>selenium-central-framework</artifactId>
<version>2.0.18</version>
</dependency>
Question :
I couldn't understand from where that dependancy was taken from ?
Solution Tried :
I have tried searching in the maven repository still couldn't find
anything related to "selenium-central-framework"
I have checked the dependencies of selenium RC, but they seems to be different from the one that is present above.
I have researched whether any local jars were used and were linked
as dependancy. However I understand from maven repository, local
repositories will be linked with the tag "systemPath"
<dependency>
<groupId>ldapjdk</groupId>
<artifactId>ldapjdk</artifactId>
<scope>system</scope>
<version>1.0</version>
<systemPath>${basedir}\src\lib\ldapjdk.jar</systemPath>
</dependency>
</dependencies>
Note that the depedency used in my project doesn't have the tag "systemPath".
Is there anyway the external repositories could be added without mentioning systemPath ??
Please help, what could be that dependency ? How to find more information about it. Thanks a ton for your help.
I suggest you one of these approaches:
Jar file
If you have access to the jar file called : selenium-central-framework-2.0.18.jar, open a command line pointing to the folder of this jar and execute:
mvn install:install-file \
-Dfile=selenium-central-framework-2.0.18.jar \
-DgroupId=com.xxxqa.selenium \
-DartifactId=selenium-central-framework \
-Dversion=2.0.18 -Dpackaging=jar
Source code file
If you have the source code of : selenium-central-framework-2.0.18.jar, open a command line pointing to the folder of this source code and execute:
mvn clean install
After one of these approaches, selenium-central-framework-2.0.18.jar will be available in you local maven repository ($HOME/.m2) and your other java maven projects will be ready to use it as dependency:
<dependency>
<groupId>com.xxxqa.selenium</groupId>
<artifactId>selenium-central-framework</artifactId>
<version>2.0.18</version>
</dependency>
This is a workaround if you don't have a server to host an artifact repository management server like :
https://www.sonatype.com/nexus-repository-sonatype
https://www.jfrog.com/confluence/display/RTF/Maven+Repository
Explanation
Almost all free, public, safe, useful and cool java libraries are hosted in https://mvnrepository.com . So any person in the world can use it in their maven project with this piece in their pom.xml:
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>3.141.59</version>
</dependency>
But in some cases, publish your source code to https://mvnrepository.com is not an option:
Oracle Driver. This driver (.jar) can only be downloaded from the official Oracle page. Private source code like IBM, Microsfot,etc
Source code of your company that should not be public.
Some super cool library that is only in github but not in the maven central repository.
So in this cases, the best and scalable solution is host and configure some artifact repository management server like :
https://www.sonatype.com/nexus-repository-sonatype
https://www.jfrog.com/confluence/display/RTF/Maven+Repository
This platforms are an emulation of https://mvnrepository.com . So with a minimal configuration:
You can host your special or private jars
Your maven projects could use this jars with the standrad xml dependency in pom.xml.
If you don't have a server to implement one of these platforms, the previous approaches could help you and get the same results
I have a few dependencies in Project Structure/Libraries in IntelliJ 14. How can I add them to my maven pom.xml? There is one single tutorial on IntelliJ's website that does not work for me. I don't want to manage them manually.
The proper way to do this would be to install the dependency artifacts (most likely jars) into your local maven repo, like this.
How to install artifacts to your local maven repo
And then add the dependencies into your pom.xml
<dependencies>
<dependency>
<groupId>com.something</groupId>
<artifactId>artifact</artifactId>
<version>1.2.3</version>
</dependency>
</dependencies>
Yes, this does require going through each artifact manually, one at a time, but it's a one time setup process.
That is the "proper" way. After that, you can do away with library dependencies in your project structure (they will be picked up correctly via maven).
There is the alternative possibility to "hack" in your project libraries path as a sort of "embedded" maven repo in your project, but that's a little bit hacky and I wouldn't advise that.
When I right click on my Maven project and choose the Add dependency option and I type my external jar's name in query, it is not found. How to add external jar to a Maven project?
From the NetBeans forum:
Open the Projects tab.
Right-click on Dependencies.
Select Add dependency.
Set groupId to: group.id (can be anything)
Set artifactId to: artifact.id (can be anything)
Set version to: 1.0 (can be anything)
Click Add to continue.
Dependency is added to pom.xml and appears under the Libraries node of Maven project. Continue:
Expand Dependencies.
Right-click on library (e.g., group.id).
Select Manually install artifact.
Set Artifact to install with the Java Archive (.jar) file path.
Click Install locally.
Library is installed locally with dependency attributes (coordinates) entered in steps 4 - 6.
I found those instructions helpful when going through the NetBeans GUI. Basically when right clicking to add a dependency, the group id, version, and name must be populated with anything. Then that "dependency" will be listed in the dependency drop down. Right click on that newly created dependency and right click to install locally and navigate to the appropriate jar file.
You can follow this tutorial:
http://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html
Example:
Install the jar to your local maven repository:
mvn install:install-file -Dfile=cxf-2.7.3.jar -DgroupId=org.apache.cxf -DartifactId=cxf-bundle -Dversion=2.7.3 -Dpackaging=jar
Edit the pom.xml file in your project to include the newly added dependency:
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-bundle</artifactId>
<version>2.7.3</version>
</dependency>
This should work regardless of the IDE you are using.
In Netbeans, the approach to adding dependencies that are not in repository is reversed. First come up with maven coordinates in the Add Dependency dialog. Then right click on the new dependency node and trigger "Manually install Artifact" action.
This answer is for jars that are in the maven repo
Let's say I want to add log4j-1.2.17.jar to my project, all I have to do is find it in maven repository
Step 2 is to copy that and place it inside the dependencies tag of your pom.xml` file:
<dependencies>
<dependency>
<groupId>org.webjars</groupId>
<artifactId>bootstrap</artifactId>
<version>3.3.4</version>
</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
....
....
<dependencies>
Step 3 Build and clean your project. The jar file will be in your dependencies folder afterwards
one trick is in the netbeans main menu select: profile->options->java->maven put in the global execution options the parameters example: -Dfile=C:\Users\anonym\Desktop\commons-pool-1.6.jar -DgroupId=commons-pool -DartifactId=commons-pool -Dversion=1.6 -Dpackaging=jar
where de parameter -Dfile is the location of the jar file
-Dfile=routeToJar
after that select your project. then rigth clic on the select project. and then select Run Maven->Goal. when the wizard appear type in as Goals install:install-file .. and then clic OK buttom

I'm following the example above for the maven nar plugin, but I get the following error when I do a mvn package
“could not find artifact net.sf.antcontrib:cpptasks-parallel:jar:1.0-beta-5-parallel-1-SNAPSHOT” but I see the following folder tree and its contents in my ~/.m2/repository... What gives?
~
.m2
repository
net
sf
antcontrib
cpptasks-parallel
1.0-beta-5-parallel-1-SNAPSHOT
Change dependency
<dependency>
<groupId>net.sf.antcontrib</groupId>
<artifactId>cpptasks-parallel</artifactId>
<version>1.0-beta-5-parallel-1-SNAPSHOT</version>
</dependency>
to
<dependency>
<groupId>org.codeswarm</groupId>
<artifactId>cpptasks-parallel</artifactId>
<version>20121119</version>
</dependency>
Unfortunately, neither maven-nar-plugin nor cpptasks-parallel are currently deployed to Central. So you need to mvn install them yourself (or better, mvn deploy them to your own Maven repository). You can find both projects on GitHub.
EDIT: nar-maven-plugin version 3.0.0 has been released, and is now available from Maven Central. Two notes:
The groupId and artifactId changed; the GAV is now:
<plugin>
<groupId>com.github.maven-nar</groupId>
<artifactId>nar-maven-plugin</artifactId>
<version>3.0.0</version>
</plugin>
The cpptasks-parallel project has been merged into nar-maven-plugin, so no need to worry about that dependency anymore.
I am using Netbeans to build a Maven project, and have the JTidy java library as a dependency. It turns out JTidy doesnt exist in any maven repos, so I can't just add a "normal" depedency entry for it.
What is the best way of handling dependencies to libraries in Maven projects that arent available on repos?
I've currently tried adding it to my maven pom as such (after copying the jar to my projects /libs folder)
<dependency>
<groupId>org.w3c</groupId>
<artifactId>org.w3c.tidy</artifactId>
<version>9.3.8</version>
<scope>system</scope>
<systemPath>${basedir}/libs/jtidy-r938.jar</systemPath>
</dependency>
However it complains that it will be unresolvable by dependent projects.
First of all, it's under another groupId, that's why you didn't find it.
<dependency>
<groupId>net.sf.jtidy</groupId>
<artifactId>jtidy</artifactId>
<version>r938</version>
</dependency>
Jtidy
But to answer your question, one way of doing this is to manually install it in your local repo as described here.
The best way IMHO is to add it to a proxy like Nexus. That way other people can access it from there without having to install it locally. However, this means you have to set up a repository manager, which doesn't make much sense if you are the only developer on the project.
