I am using the last version of Modbus4J 2.0.2, converted to use Maven for dependency management.
In my first Modbus4J project (1 year ago), I only add the different *.jar to my project and it works fine. (modbus4J.jar, seroUtils.jar, RXTXcomm.jar)
But now I can not do it, if I add the new jar on my project I can see a lot of build errors, regarding for apache libs...
I am using Eclipse and I installed the maven plugin but I do not know how I can insert the libraries in my project.
Do you know How Can I build and test the files of com.serotonin.modbus4j.test of Modbus4J 2.0.2? (MasterTest.java, ListenerTest.java...)
And How Can I integrate the new Modbus4J libraries on my project?
The library is here:
https://github.com/infiniteautomation/modbus4j
Thanks in advance,
Best regards.
Look at the pom.xml file in the modbus4j project. You'll see that it declares a local file based repository (modbus4j-local). That is where the serotonin-timer & serotonin-utils dependencies are stored.
If that doesn't help you, then it's not clear what you are trying to do. Consider posting your project's pom.xml file contents and/or the important build error messages you are seeing.

I am currently using the Eclipse IDE and want to import an external java project so that I can use it in something I am working on. I downloaded the directory of icePDF, found here, and would like to use the java class file "SwingViewBuilder.java" that is found in the directory I linked at "/icepdf/branches/icepdf-6.2.5/icepdf/viewer/src/org/icepdf/ri/common". I have tried some basic things like importing the folder itself, but it did not work.
I would highly suggest using a dependency management tool like Maven or Gradle to download this dependency and any other dependencies you may have into your project for you.
Here is the maven getting started guide: https://maven.apache.org/guides/getting-started/
And here is the maven dependency for you to add to your pom.xml file: https://mvnrepository.com/artifact/org.icepdf.os/icepdf-viewer/6.2.2
If you specifically need version 6.2.5, you will need to build the icePDF project yourself and configure your class path to use it as a dependency.
I am new to writing build files and currently I am writing the ant for my project. The issue I am facing is to include the jar to in ant build file.
As per the standard 'ant build' the jars need to be kept in lib folder. But the issue is the jar is very huge, more than 100 GB of size and hence cannot be kept in GitHub.
I have put that in another repository and want to include that in my build file.
Could anyone please let me know how to include the jars in my 'pathelement location' from the url.
Apache ivy is a 3rd party dependency manager, a powerful feature built into more modern Java build tools like Maven and Gradle.
The following answer gives a detailed example, using ivy to manage classpaths and help in the creation of an executable jar.
Class not found with Ant, Ivy and JUnit - error in build.xml?
You mentioned the use of another repository. Presumably this is a Maven repository manager like Nexus or Artifactory. Ivy is capable of downloading from these. (which would be another question :-))
From hibernate.org: http://hibernate.org/validator/documentation/getting-started/
I saw Prerequisites:
Java Runtime >= 6,
Apache Maven
However, "maven" is not even mentioned in the following:
http://www.aviyehuda.com/blog/2010/04/14/using-hibernate-validator-to-cover-your-validation-needs/
Our current project is not maven-based, a student project. Could we still use hibernate validator without using maven? Or is there any better choice for hibernate validation?
Maven is not required. The main reason you want to use Maven is that it makes downloading all the package dependencies super easy.
If it's just a small student project, and you don't want to use Maven, then just download the jars that you would otherwise have downloaded with Maven.
You can manually download the jar files here : http://hibernate.org/orm/downloads/
Maven is optional. But it's a very helpful tool for building Java projects (via many phases like compile, test, package, install...). You'd better learn to use it.
In your question, the hibernate-validator jar will depend on other jars such as hibernate-jpa, validation-api, joda-time...
It means you can not run your project with only hibernate-validator jar file. You need to collect all the required jars together.
Maven will automatically resolve it for you.
You can download from:
https://repo1.maven.org/maven2/org/hibernate/hibernate-validator/5.2.4.Final/hibernate-validator-5.2.4.Final.jar
Then add this file jar to your project manually. As you seen, downloading jar file is an alternative way when not using Maven.
I have been trying to use the vget library/api to make my own youtube video downloader. The vget library can be found here: https://github.com/axet/vget
I have downloaded the zip on github and I imported the project into eclipse. However, I am confused to how I am supposed to properly use this API. Should I make a completely new project, and import the classes that I need or do I put my own source files in the project of the api?
I have read other threads concerning this problem. However, they all mention how a api is typically packaged in a JAR file, but in my case it is just files and classes. So I am confused to how I should properly use this api.
The vget project is a maven project. You can see that because it has a pom.xml file in the root folder of the project.
To use it, you don't even need to download the source, because the compiled jar files are already stored in the central maven repository. You can find more information about this here:
http://mvnrepository.com/artifact/com.github.axet/vget/1.1.23
(in general, you can use the http://mvnrepository.com/ site to search whether your library is available on the maven central repository. If it's even a mildly popular library, then chances are that it is)
What you need to do is to make your own project a maven project.
Here's a "5 minutes" starter guide that describes how to do that.
When you've done that, you just add the dependency on vget to your pom.xml file in the <dependencies> section:
<dependency>
<groupId>com.github.axet</groupId>
<artifactId>vget</artifactId>
<version>1.1.23</version>
</dependency>
Since you are making use of a 3rd party software, and not extending it with your own logic, the way to go is to create a new project, which references the 3rd party software.
You then construct your application and make it do whatever you need it to do. When it comes to using logic which is available within the 3rd party logic, you would then simply delegate that call to the 3rd party library.
I have seen on the link you have provided, that this is a maven project. You have to execute a maven package command, or maven install, so that the jar file will be generated.
With this jar follow the Bill's instructions, and add it as external library to your claspath.
When you do this, you will be able to invoke methods of that api.
Let us know if you need some help doing this in eclipse.
If your project is a maven project, you can solve dependencies problems just adding the dependency written on Readme file to your pom file.
The easiest and most automatic way is to use something like maven, ant, or gradle, that will automatically download and put the jars in to your classpath if they are in the central repositories. For example, in the maven configuration file(pom.xml) you can add this to the dependency list:
VGet Maven Repository
These build tools also allow you to add external jars if needed.
If
I would suggest you get familiar with Maven. At the bottom there is a Maven dependency you just have to include into your pom.xml, and then you can use the extension immediately.
Maven is a build platform which organizes your project in a technical way (convention over configuration, e.g. code is in /src/main/java, tests are in /src/test/java). The proper way is it to create a Maven project in Eclipse (you have to install the plugin and download Maven as well) and put the dependency
<dependency>
<groupId>com.github.axet</groupId>
<artifactId>vget</artifactId>
<version>1.1.23</version>
</dependency>
into your <dependencies> inside your pom.xml. After adding it, you project recognizes the additional package automatically.
Nobody tinkers by adding libraries manually. It's actually not professional to work without a build platform like Maven or Gradle.
I use Maven and CouchDB. I put a CouchDB java library dependency in pom.xml and recompile using maven. I see that files get downloaded and the compilation succeeds with no error, but IntelliJ that I use can't find this library or its classes.
I used ektorp, couchdb4j and jcouchdb, but had the same problem. Any help?
If you have opened the project by using [File]->[Open Project...] and then point on the pom.xml then IntelliJ will keep track on changes/updates in the pom.
Do not use the maven-idea-plugin since it is obsolete, last changes are from 2008.
Have a look into a working example and compare it with yours https://github.com/softberries/woodstoxex (couchdb branch), for pure MFN project you can create an IntelliJ project using 'from existing model' option and selecting maven from the list
