I tried all the suggested solutions which found on Stackoverflow but didn't solve the issue with Maven repositories in Intellij IDEA. The problem is that I can't find needed jars in local repository, even if I update it. Central repository is impossible to be updated. Just for example: I use in web-app servlet api (jar is found in local repo but the version is 2.5), jstl and jdbc. If I don't create Maven project I just add all the external libraries to the project manually. But in the case of Maven-project I do not add nothing but try to create dependency through Alt + Ins when writing the class. Result - there are not needed jars in local repository.
What I tried:
1.Installed/deleted a couple of versions of Maven (The current is 3.2.2)
2.Defined local repository in settings.xml (the tag missed by default)
3.Updated local repository
4.Added dependency manually in pom.xml but IDEA didn't define it
Moreover, when I created a first Maven-project in IDEA according to web-app archetype it didn't have needed folders structure but started donloading the number of jars. Current version of IDEA is 13.0. If somebody faced such problem please help me to eliminate it.
But in the case of Maven-project I do not add nothing but try to
create dependency through Alt + Ins when writing the class. Result -
there are not needed jars in local repository
You actually have to perform an maven install, this downloads the jars from whereever to your local repository. Just writing the depenecy in pom, doesn't actually download them.
This is how maven works, nothing to do with intellij.

I am setting up a local repository using Apache Archiva. After setting up now I need to copy the libraries that got downloaded into my local maven repository into archiva. Currently I am manually copying it but it is very tedious process and I am planning to automate it using some scripts. Is there any better approach to do this?
I'm trying to write a plugin for this here which is able to copy jars and poms for all dependencies in all Configurations (including transitive dependencies). You might be interested in this code
Note: I've got a failing test here because I can't currently get the parent pom xml via the Gradle API's. I raised a feature request in Gradle here
There's a suggestion on the issue to use the IvyPot plugin... I haven't tried this myself but might be worth a shot.
Recently I have upgraded maven from 2.x to 3.x and then deleted the total .m2 repository from Users and again generated .m2,
Everything looks good but I want get the confirmation from repository should these all are generated using maven 3.x.
Can some one help me out?
In order to make sure that the dependencies are downloaded through your new maven version. You can add a dependency, which does not exist in your local repository, through your new project, which uses maven 3 and you run the mvn clean install command in the path, in where you parent pom is and then, you can check whether this new dependency in your local repository or not. However, as SiKing said, the content is independent from the version of the maven. You can make a small test like i described.
I want to use Jmathplot.jar
I tried to put it as a dependency
<dependency>
<groupId>jmathplot</groupId>
<artifactId>jmathplot</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${project.basedir}/lib/jmathplot.jar</systemPath>
</dependency>
but when installing I get this error:
Some problems were encountered while building the effective model for com.NResearch:dable-start-tRisk:jar:0.1-SNAPSHOT
[WARNING] 'dependencies.dependency.systemPath' for jmathplot:jmathplot:jar should not point at files within the project directory, ${project.basedir}/lib/jmathplot.jar will be unresolvable by dependent projects # line 44, column 19
How can I get around this please?
EDIT1:
I cannot change Maven to include all dependent jars into a single jar. As this is uploaded to a web project.
"Dependent" is using your project, "dependency" is used by your project.
The real error here is that jmathplot.jar is in a folder that can really only reliably be found by your project. Even though your dependents know how to find your artifact in the local repository, they won't know where the sources are for your artifact, hence won't be able to find lib/jmathplot.jar. You can fix that by changing the systemPath to an absolute path. It can still be parametrized, but then please use properties rather than implicit properties (such as ${project.basedir}.
It'd be better to get rid of the systemPath dependency, by installing jmathplot into a company repository, so it can be used alike 'normal' artifacts. But that may not be a useful option if you have to distribute your artifact out of the reach of your company repository. It would even be better if jmathplot would just get deployed to the Maven central repository.
As a last resort you may choose to bundle the dependencies (not the dependents). You can do this:
Using the Maven Shade Plugin. It lets you choose which packages to include which may be useful to bundle only jmathplot (and not other dependencies).
Using the Maven Assembly Plugin. It has a predefined descriptor for "JAR with dependencies" which would fit your use case. You could create your own descriptor off of that example and set dependencySets.dependencySet.scope=system to only include the system dependencies that are giving you trouble.
Best way is to install your dependency on your local repository. To do this:
1) using project source, install to local repository using mvn install
2) if you don't have source code, install to local repository using this
hope it's help
nota: you are spamming around this question, do you ? (see here: JMathPlot what is the Maven dependency code please )
I am upgrading a project from Ant to Gradle. The project uses a aqapi13.jar(this is oracle aq jar. This is needed as the project reads from an oracle-queue and writes to an activemq queue.)
The ant project contains the jar aqapi13.jar in the libs folder. But iam trying to get this dependency from a repository instead of having it in the libs folder.
However, iam not able to find a repository which contains this jar. All the repositories that I have seen contain aqapi13-9i.jar, but not aqapi13.jar.
Anyone knows the difference between aqapi13.jar and aqapi13-9i.jar and how to get the needed aqapi13.jar from a repository.
Advance Thanks
Some dependencies are never found in public repositories because of the license they have.
One way to use this dependencies is to create your own repository (e.g. artifactory, nexus, archiva). Then you are free to put in every artifact you want (as long as you do not publish the repository). This repository can also serve as a mirror for maven.
Another way could be to mark this dependency as system scope.
I am having a java project with a ant build file, using this ant file i create an ejb of the project and deploy it on the jboss server.
Now I am planning to use maven and convert this existing project which consist of nearly 28-30 jar's in its class path(jars related to ejb3, hibernate, jboss, etc).
I can easily do it using eclipse i.e right click project goto maven and click Conver to Maven.
A pom.xml is generated and the MavenClassPath Container is also added to the project.
Now I want to know how to get rid of those 28-30 jar's present in the lib folder of the project and in the classpath. i.e. I want my pom.xml handle all the dependencies.
Does Maven provide any mechanism to achieve this goal while converting the project or I have to add all of these jar dependencies one by one manually in the pom.xml file.
The intention of doing this is I want to have common maven remote repository where the jars will be stored and each developer machine will point to it through their maven project.
Thanks
I think you're after a repository manager like Nexus (I use Nexus, it seems to be the most popular http://nexus.sonatype.org/ ).
Nexus can be used as:
A proxy repository (for Maven Central, etc)
A repository for your own releases.
Nexus provides user management for your developers to release builds into the repo.
Developers will then point their Maven settings.xml file to your Nexus repository, and all their dependencies will come from here (Nexus will cache them).
I'm afraid you will have to configure the dependencies individually, but that is a good thing, because you should pay attention to what version ranges you are interested in for each dependency.
Any jars which can't be found in Maven Central, etc, you can add to your own Nexus repository .
Ofcourse there are alternatives to Nexus, but I haven't used any.
HTH
The most important thing i can recommend is to use a Maven Repository Manager (Nexus, Artifactory or Achiva or other..).
Second your pom conversion via Eclipse shows me that you are not using an up-to-date Eclipse nor an up-to-date Maven Plugin for Eclipse. The best thing would be use Eclipse-Indigo (m2e is the newest and greatest).
Furthermore you have to go through all your jar's and add them step by step to you pom (dependencies) and see if your project can be compiled. This should be checked on command line not inside Eclipse.
After you got a working pom.xml file put it into your version control and check if you can remove some of your added dependencies based on transitive dependencies. After that you can finally delete your lib folder.
