I have an application that streams Twitter data using Twitter4j. In Maven Dependencies, I've got the 4.0.2 version, but I want to update to the 4.0.4.
How do I do that? In Configure Build Path it is not possible to edit the selection of the jar file.
This is the major advantage of using Maven, that it fetches the required jars and caches it for your further usage.
You don't have to download the updated JAR, just update the version number of the JAR in your Maven POM file and do a clean and rebuild.
When you do that, Maven will check your local repository (cache) and, if the jar hasn't already been downloaded, it will go to the maven repositories, find a copy, and download it (this is assuming you didn't do an offline build!), then it will use that copy to do your new build with.
<dependency>
<groupId>org.twitter4j</groupId>
<artifactId>twitter4j-core</artifactId>
<version>4.0.4</version>
</dependency>
Hope that this helps!
Updating your pom.xml by adding this snippet in the dependencies section:
<dependency>
<groupId>org.twitter4j</groupId>
<artifactId>twitter4j-core</artifactId>
<version>4.0.6</version>
</dependency>
Note, that there are several important fixes incoming with 4.0.6. For example, the support for enhanced_media_entities is added, which is quite important for compatibility reasons with Twitter API.

So I'm new to maven and watching a course on how to download hibernate-core using maven,
and he went online and got the 5.2.11 version
but I downloaded the latest one 6.1.4
the thing is when he opened his local files the jar files were there like this:
but my version only downloaded these files, even when I removed the type pom:
and when I tried the older version it worked for me, so my question is why did maven do that, and does it make any problem?
also, can I now use hibernate if I don't have an internet connection, or do I need to download the jar files anyway?
NOTE: I'm using Eclipse
Your dependency is declared in a different way from the official documentation. They don't specify a <type>pom</type>, which may be the cause of your problem.
They have it like this:
<dependency>
<groupId>org.hibernate.orm</groupId>
<artifactId>hibernate-core</artifactId>
<version>6.1.4.Final</version>
</dependency>
Remove the type and rebuild the project.
I am writing one utility job in java to download JSON files from particular URL of Gitlab account and further process them according to requirement. I tried to do same using java-gitlab-api dependency. However, even after including below maven dependency,
I get error as :
Missing artifact org.gitlab:java-gitlab-api:jar:1.1.8-
The import org.gitlab cannot be resolved.
Maven dependency I am using is :
<dependency>
<groupId>org.gitlab</groupId>
<artifactId>java-gitlab-api</artifactId>
<version>1.1.8-SNAPSHOT</version>
</dependency>
I tried to update, clean maven project but nothing worked. Anyone has an idea of how can I rectify issues and download files from gitlab account.
Use appropriate maven java-gitlab-api version(s). There is most recent version is available too.
https://mvnrepository.com/artifact/org.gitlab/java-gitlab-api/1.1.8
https://mvnrepository.com/artifact/org.gitlab/java-gitlab-api
<!-- https://mvnrepository.com/artifact/org.gitlab/java-gitlab-api -->

I need to add the package "uk.ac.shef.wit.simmetrics.similaritymetrics"
to my maven project but I am not able to find any remote repository which contains it. I have to add it via dependency to the project, but not successful yet.
-I already added the jar file to the referenced library but in that wat I get the following error:
package uk.ac.shef.wit.simmetrics.similaritymetrics does not exist.
-Adding it through following dependency to the Pom.xml also does not help
<dependency>
<groupId>uk.ac.shef.wit</groupId>
<artifactId>simmetrics</artifactId>
version>1.6.2</version>
<scope>system</scope>
<systemPath>LocalPath\simmetrics-1.6.2.jar</systemPath>
</dependency>
Any help is appreciated!!
If this is a small project that you intend to only build locally or on a few machines then the simplest way is follow directions at the site below to add a 3rd party jar. Those instructions will help you install it in your local repository. You will need to do that for all machines that you intend to run the build on.
https://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html
If you plan to run it on many machines then the best thing to do is to install the artifact to your own private repository. If that is the case then I suggest you create a project for it in version control. Then upload the file as part of that project.
I appear to be the current maintainer of Simmetrics. You can add this dependency to your pom file.
<dependency>
<groupId>com.github.mpkorstanje</groupId>
<artifactId>simmetrics-core</artifactId>
<version>4.0.1</version>
</dependency>
Simmetrics has been given a much needed serious overhaul since 1.6.2. You may have to adjust your code accordingly. For source code and documentation see https://github.com/Simmetrics/simmetrics
I cant find javax.ejb.jar in my .m2 dirctory, I need this jar for import javax.ejb.Schedule; , here is my pom file entry.
<dependency>
<groupId>javax.ejb</groupId>
<artifactId>ejb-api</artifactId>
<version>3.0</version>
<scope>provided</scope>
</dependency>
I am not sure if it will work or not, or its a right way to do things. Can some one please help to make a change in the POM file so that it downloads javax.ejb.jar into the .m2 directory.
Updated
by .m2 I mean in the repository directory in the correct folder
hierarchy (What ever it is).
Why? We have multiple sub projects (In eclipse workspace), In order to resolve dependency we use M2_REPO/path/to/the/required_library_file.jar, Now theses projects are part of code bases, Every developer download the source code, Maven download all jar to the repository directory(of the developer using any OS/Platform). This relative path from M2_REPO helps developer to have consitenat code (for eclipse project). Otherwise everyone will be adding their own path.
If it still doesn't make sense, here is what I want, Please give me an entry for POM file which download the javax.ejb.jar file into .m2 directory what ever the sub path is.
I have to include this jar in every project manually (And every developer needs to them as well from what ever directory have glassfish (C: , D:, E:, or /home/glassfish/modules/)
D:\servers\glassfish-3.1.2\glassfish3\glassfish\modules\javax.ejb.jar
where rest of the jars in each project are included as M2_REPO/path/to/jar which makes less no changes in the code base to commit.
M2_REPO/javax/ejb/ejb-api/3.0/ejb-api-3.0.jar
M2_REPO/javax/enterprise/cdi-api/1.0-SP1/cdi-api-1.0-SP1.jar
M2_REPO/javax/inject/javax.inject/1/javax.inject-1.jar
etc etc
I think I hear what you mean now :)
The maven dependency you specify
<dependency>
<groupId>javax.ejb</groupId>
<artifactId>ejb-api</artifactId>
<version>3.0</version>
<scope>provided</scope>
</dependency>
which you have in .m2/repository/javax/ueb/ejb-api/3.0/ejb-api-3.0.jar does not contain the class/interface javax.ejb.Schedule.
But you found the jar-file in your glassfish server, which does contain javax.ejb.Scheduleand its name is D:\servers\glassfish-3.1.2\glassfish3\glassfish\modules\javax.ejb.jar and now you ask how to get that into the pom?
Well, the Java EE APIs and their official jars in maven are somewhat a study in disharmony.
If you run a search on maven central you will find multiple jars containing exactly that class. You will probably note that all appserver vendors provide their own edition of every aspect of every api in every version.
You should be able to find a jar with the javax.ejb module from glassfish in version 3.1.2
http://search.maven.org/#artifactdetails|org.glassfish|javax.ejb|3.1.2|jar
in which case the dependency would be
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.ejb</artifactId>
<version>3.1.2</version>
<scope>provided</scope>
</dependency>
I found another artifactId here, though maven has your version too.
A (very) weird maven caching problem? Then it might work tomorrow.
<dependency>
<groupId>javax.ejb</groupId>
<artifactId>javax.ejb-api</artifactId>
<version>3.2</version>
</dependency>
Though this is a new version, for compilation it should do.
You may need to provide the repository location in your pom.xml file or in .m2/settings.xml file for the required jar to get downloaded into .m2 directory.
The dependency is declared as provided what means that the container will provide it.
What container are you using? I think Tomcat/Jetty won't provide that jar as it seems so Java EE. In that case just change the scope to compile.
<dependency>
<groupId>javax.ejb</groupId>
<artifactId>ejb-api</artifactId>
<version>3.0</version>
<scope>compile</scope>
</dependency>

I recently moved to maven project and since then I found adding dependencies very difficult. Before that I just needed to download the jar and add to library folder .
Now I am searching flash-selenium.jar dependency but I failed to find any. So I added it manually in my C:.m2\repository\org\seleniumhq\selenium\flash-selenium folder but still it is giving error. So how can I use this jar in my maven project?Its a request to people those have 1500 points here , could you please create a label for selenium flash related problems. Thanks
There's no flash-selenium dependency in maven central, but there are other artifacts like:
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium</artifactId>
<version>2.0rc2</version>
</dependency>
the complete list:

Maybe some of this fits what you need.
