I'm trying to use one of the Apache Commons Math3 classes in Eclipse.
Downloaded the jar, and used these instructions for adding to the build path: ClassNotFoundException in eclipse.
In addition, since the project uses Maven, I added this to the pom.xml file:
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-math3</artifactId>
<version>3.0</version>
</dependency>
Here is where I'm using the class:
import org.apache.commons.math3.distribution.fitting.MultivariateNormalMixtureExpectationMaximization;
...
MixtureMultivariateNormalDistribution mmnd = MultivariateNormalMixtureExpectationMaximization.estimate(data, 2);
There are no errors at compile time, but at runtime:
Error text:java.lang.ClassNotFoundException: org.apache.commons.math3.distribution.fitting.MultivariateNormalMixtureExpectationMaximization
I know there are a couple of stackoverflow answers regarding adding jar files, I've followed several of them and they don't seem to solve the issue.
Thanks in advance!

This seems like it should be simple but I cannot find anything on how to upgrade to newer versions of itext7. I am using an Eclipse maven project with itext7 version 7.0.4 and would like to update to 7.1.1. However, I can find nothing that tells me how to do that. Neither the Eclipse update menu or the Maven menu has an option to update itext7. Can someone point me to the documentation on how to do an update? TIA.
After answer:
I am not getting the libraries but instead getting conflicts:
I can't seem to post my pom.xml using code tags (I guess the formatter has a problem with XML code because of the <>) but I will include it if someone tells me how. I've uploaded the pom file to DropBox:
pom.xml
(Turning #mkl's and #amedee's comments into an answer)
In your project there is a file pom.xml which contains the Maven project definition. In there is a dependencies section with entries for the iText artifacts (among others). The version is therein. Well, it could also be in a separate dependencies management section or in a parent pom.xml referenced in your file.
As soon as you update the POM file, you can update the Eclipse project configuration in your Eclipse Maven menu. That will, if necessary, automatically download the jar artifacts. If your Eclipse Maven integration is properly configured, that is, and if your computer has proper internet connectivity.
Old versions will remain in your local repository but won't be in the class path anymore.
Also check out our getting started guide. Which contains an example POM snippet.
https://developers.itextpdf.com/itext7/download-and-install-information/Java
If you put your iText version number in POM properties, then you only have to update the value once when you want to upgrade. Like this:
<properties>
<itext.version>7.1.1</itext.version>
</properties>
and then
<dependencies>
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>kernel</artifactId>
<version>${itext.version}</version>
</dependency>
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>io</artifactId>
<version>${itext.version}</version>
</dependency>
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>layout</artifactId>
<version>${itext.version}</version>
</dependency>
...
</dependencies>
Created the maven scala project.
I had correctly specified all the configuration . But still facing this error.
any help appreciated.
I solved this error.
Its coming because I had make the entry for org.scalatest plugin and there is no src/test/scala dir and no test cases.After removing org.scalatest plugin entry from pom file everything work fine.
For anyone that comes across this issue in the future, make sure you have the following dependency in your pom.xml.
<dependency>
<groupId>org.scalatest</groupId>
<artifactId>scalatest_2.11</artifactId>
<version>3.0.0</version>
<scope>test</scope>
</dependency>
I have a web dynamic project on eclipse running on Tomcat.
I need to add the dependency of the JWT library on Maven dependencies. So I configured my project to Maven, and the I added the dependency on the pom.xml.
Now eclipse doesn't resolve my dependency, for example if I import a package of JWT there is a red line that highlights my import.
But there is another problem:
all the library that I imported like hibernate, apache-common (that I previously copied in WEB-Lib) that before worked, now are unresolved.
How may I face this problem? This is the first time using Maven, so if I'm wrong in something, please tell me.
Thanks in advice.
<dependency>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt</artifactId>
<version>0.6.0</version>
</dependency>
This dependency worked for me
I have a pom.xml with the following entry
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>3.1.0.RELEASE</version>
</dependency>
And on maven install the jar is added to the maven repository and is also listed in the maven dependencies library.
But I am not able to import any of the classes from the added jar 'spring-web-3.1.0.RELEASE.jar' for the particular entry, though it shows in the classpath
The error - in eclipse "cannot be resolved to a type"
environment - maven 3.1 and Spring tool suite
Thanks
Solved - found the solution through some other forum
The jar inside the repository was corrupted.
After clearing the .m2 folder in the physical drive and repeating the maven clean install worked.
Thanks for the time #techidiot #jtravaglini.
I'm new to Eclipse/STS, and I am having deploying to Tomcat / tcServer. My project builds just fine and deploys to Tomcat fine both in Netbeans and directly to Tomcat, but it will not deploy to Tomcat or tc Server in Eclipse. I get a ClassNotFoundException for org.hibernate.HibernateException, which I know is on the included in the pom.
Here's my log output if it helps.
Also in the markers view, I see the following build path problem:
Archive for required library: '~/.m2/repository/org/hibernate/hibernate-core/4.1.1.Final/hibernate-core-4.1.1.Final.pom' in project 'flamespass-web-dev' cannot be read or is not a valid ZIP file
I found a work around:
I noticed that I had hibernate-core:4.1.1.Final in my Dependency Hierarchy twice, so I tried a few things, and specifying the newest version of hibernate-core in my dependencyManagement node fixed my problem.
I am not sure why. I can only assume that the two copies of hibernate-core:4.1.1 were creating some sort of ambiguity that m2eclipse or WTP couldn't understand even though my external Maven/Tomcat could. I would really appreciate any explanation or better fixes anyone may have. Thanks.
