I use the jersey first in maven. In maven it look like this:
pom.xml:
<!-- jersey -->
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-servlet</artifactId>
<version>2.25.1</version>
</dependency>
and it can run the jersey server.but when I change to use the jar way. It doesn't work!
the jars list:
enter image description here
OK! I fix it by myself. because after the project compile, the jars doesn't put in the target lib. So I put all the jars in the lib,it can work!

I copied some code from github and I have a problem with libraries. My code looks like:
When i click on Authentication to add a maven dependency
it shows that there is no results
What I do wrong? Should I install anything before clicking "add maven dependency" ?
Add
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-core</artifactId>
<version>5.4.0</version>
</dependency>
To your pom.xml
Or just search for another dependency. https://mvnrepository.com/
You need to add maven dependency in pom file:
https://mvnrepository.com/artifact/org.springframework.security/spring-security-core
I am moving some test code from an older jHipster project to a new one. The old project uses the org.springframework.cloud.netflix.zuul library, specifically org.springframework.cloud:spring-cloud-netflix-core:1.3.0.RELEASE .
I put the below in my new project's pom.xml:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-zuul</artifactId>
<version>1.3.0.RELEASE</version>
</dependency>
However, it seems to be pulling in org.springframework.boot:spring-boot:2.2.5.RELEASE. This release does not contain zuul in it however, as this code fails import org.springframework.cloud.netflix.zuul.
Does anyone know a fix or workaround?
Old library.
org.springframework.cloud:spring-cloud-netflix-core:1.3.0.RELEASE
My new project is using
org.springframework.boot:spring-boot:2.2.5.RELEASE
UPDATE:
Sorry I updated my question - my pom file already has this code. But it is very weird to me that even though I put to 1.3.0, I can see in my maven dependencies that it's pulling in 2.2.5. Also when I right click my project, I see maven - reimport and maven - generate sources etc.. I don't see a update project. And clicking both of those doesn't seem to downgrade it to 1.3.0
If you update your pom.xml file your problem would solve.
In your pom.xml file you'll see dependencies tag you need to add the library you want and then right click your project and say maven -> update project
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-netflix-core</artifactId>
<version>1.3.0.RELEASE</version>
</dependency>
</dependencies>
Add following dependency to your pom.xml
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-zuul</artifactId>
<version>2.1.3.RELEASE</version>
</dependency>
Upgrading spring-boot to >= 2.5 requires some extra configuration in order for Zuul to keep working, see:

The dependency version I want to use is 4.5.0 as specified in my pom.xml
<dependency>
<groupId>net.java.dev.jna</groupId>
<artifactId>jna</artifactId>
<version>4.5.0</version>
</dependency>
<dependency>
<groupId>net.java.dev.jna</groupId>
<artifactId>jna-platform</artifactId>
<version>4.5.0</version>
</dependency>
However, when I run mvn clean install -DskipTest=true. Maven will download and use version 4.2.2.
libraries
I tried searching in the entire project thinking maybe there are other files(in this case pom.xml) that specify the version to 4.2.2 but found nothing.
Has anybody encountered this issue before? I'm new to Java and I can't think of any other reason as to why this is happening.
Look at the output of mvn dependency:list. It will list you all dependencies of the project with their respective versions.
This is the truth. If your Eclipse or IntelliJ or whatever list something else, they are most certainly wrong/outdated.
My webapp includes REST web services and is running on GlassFish 3.1.2.
I would like to run this app on Tomcat 7 instead of GlassFish. What dependencies should I add and remove to enable REST services on Tomcat?
(At the moment I just changed "GlassFish" to "Tomcat" in the "Run" menu of Netbeans, but my http requests give a 404.)
Note: this is a Maven project on Netbeans.
Ok here is the list of dependencies you may need. Please note I just put latest version but you may want to use a different version. Please also check for compatibility of these versions with each other.
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-servlet-core</artifactId>
<version>2.8</version>
</dependency>
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>javax.ws.rs-api</artifactId>
<version>2.0</version>
</dependency>
Needed if you are using jackson to parse json
<dependency>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-json-provider</artifactId>
<version>2.3.3</version>
</dependency>
This is what I am using on my tomcat but little bit older versions
Now about your 404
First check if the dependencies fix your problem. 404 may be an issue from some thing not configured right in your web.xml as well.
I hope it helps you solve your problem :)
I am new to Maven and am trying to set up one of my first POMs. My application will cache using EhCache. Going to Maven Central Repo (link here) I copy-n-pasted the <dependency> tag and copy it into my pom.xml like so:
...many dependencies above this point
<dependency>
<scope>compile</scope>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>4.0.1.Final</version>
</dependency>
<dependency>
<scope>compile</scope>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>2.5.0</version>
</dependency>
<dependency>
<scope>compile</scope>
<groupId>jasperreports</groupId>
<artifactId>jasperreports</artifactId>
<version>3.5.3</version>
</dependency>
...many dependencies below this point
When I save the changes, Eclipse builds the workspace and gives me an error on the opening <dependency> tag for EhCache 2.5:
Missing artifact net.sf.ehcache:ehcache:jar:2.5.0
So I figured that perhaps v.2.5.0 has something wrong with it, and repeated the same for 2.4.7 (the last 2.4.x release before 2.5.0). Same deal.
Since I'm so new to Maven, I don't even know where to begin looking. I tried Project >> Clean and even restarted Eclipse to see if it was just a typical Eclipse "quirk". Nope.
I am thinking:
Could EhCache be publishing bad JARs to the Maven repo?
Could Maven Repo have something wrong with it?
Could this be due to something else configured wrong in my pom.xml?
Could this be a "JAR hell" issue where I have a conflict somewhere on my dependency graph?
How would SO start tackling this problem? Thanks in advance!
It is usually safer to refer to search.maven.org. Dependency from there:
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>2.5.0</version>
<type>pom</type>
</dependency>
Mind type pom. From module's pom:
This is a pom artifact to pull in ehcache-core and ehcache-terracotta
for clustering. Make sure to set 'type' to 'pom' in your dependency.
Aparently when someone does not need terracotta, ehcache-core will do perfectly fine as other answer states.
They use ehcache-core in the official documentation. Maven Central does not have a jar artifact for ehcache 2.5 which explains your error message.
Using ehcache-core changes the dependency to:
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache-core</artifactId>
<version>2.5.0</version>
</dependency>
Which successfully downloads on my machine (ehcache does not).
I dropped this into IntelliJ and it found it. I suspect there is something wrong with your settings. Try creating a project with only this dependency in it. If it fails to download, I would check your setting. e.g. .m2/settings.xml Are you using a Nexus server or maven proxy/cache?
BTW: A simpler way to search for JARs is to use http://mvnrepository.com/ which will find all the available versions and show you the XML you need to add.
