What exactly is the artifact descriptor in Maven?
“Failed to read artifact descriptor” problems generally indicate a problem with the dependency’s pom file in the maven repository. I would suggest you to double check if the pom file’s name is the same with the name maven expects, and also to check if the pom file contents are valid.
Should I use Maven or Gradle?
Maven uses XML configurations, Gradle uses a Groovy-type thing that looks a little nicer IMO. If you're looking for a lot of support and maturity, use Maven. If the opportunity presents itself, I'd give Gradle a try. There's no hard determiner, but you should at least get a taste of both once in your life.
What is group ID Maven?
- groupId – a unique base name of the company or group that created the project.
- artifactId – a unique name of the project.
- version – a version of the project.
What does artifactId mean in Maven?
artifactId is the name of the jar without version. If you created it, then you can choose whatever name you want with lowercase letters and no strange symbols. If it's a third party jar, you have to take the name of the jar as it's distributed.
What is groupId and artifactId in Maven Quora?
groupId will identify your project uniquely across all projects, so we need to enforce a naming schema. It has to follow the package name rules, what means that has to be at least as a domain name you control, and you can create as many subgroups as you want. artifactId is the name of the jar without version.
How do you name a groupId and artifactId in Maven project?
Two simple rules work for me: reverse-domain-packages for groupId (since such are quite unique) with all the constrains regarding Java packages names. project name as artifactId (keeping in mind that it should be jar-name friendly i.e. not contain characters that maybe invalid for a file name or just look weird)
What is the meaning of artifactId in POM model?
modelVersion - should be set to 4.0. 0. groupId - the id of the project's group. artifactId - the id of the artifact (project) version - the version of the artifact under the specified group.
Is group ID same as artifact ID?
The main difference between groupId and artifactId in Maven is that the groupId specifies the id of the project group while the artifactId specifies the id of the project. Show activity on this post. groupId uniquely identifies your project across all projects. artifactId is the name of the jar without version.
What is group ID dependency?
The groupId is an XML element in the POM. XML file of a Maven project that specifies the id of the project group. In contrast, artifactId is an XML element in the POM. XML of a Maven project that specifies the id of the project (artifact).
What is group and artifact in spring?
Group: project coordinates (id of the project's group, as referred by the groupId attribute in Apache Maven). Also infers the root package name to use. Artifact: project coordinates (id of the artifact, as referred by the artifactId attribute in Apache Maven). Also infers the name of the project.
What is groupId and artifactId in gradle?
In Gradle, the groupId is known just as group , the artifactId is known as name , and the version is identically version .
What is Modelversion in Maven?
model version is the version of project descriptor your POM conforms to. It needs to be included and is set. The value 4.0. 0 just indicated that it is compatible Maven 3.
What is groupId and artifactId in Maven project Eclipse?
Maven uses a set of identifiers, also called coordinates, to uniquely identify a project and specify how the project artifact should be packaged: groupId – a unique base name of the company or group that created the project. artifactId – a unique name of the project. version – a version of the project.
What is groupId in Maven dependency?
groupId This element indicates the unique identifier of the organization or group that created the project. The groupId is one of the key identifiers of a project and is typically based on the fully qualified domain name of your organization. For example org. apache. maven.
What do artifactId attributes define?
artifactId. This is an Id of the project. This is generally name of the project. For example, consumer-banking. Along with the groupId, the artifactId defines the artifact's location within the repository.
What is artifact ID?
artifactId is the name of the jar without version. If you created it then you can choose whatever name you want with lowercase letters and no strange symbols. If it's a third party jar you have to take the name of the jar as it's distributed. eg. maven, commons-math.
What is group ID?
groupId will identify your project uniquely across all projects, so we need to enforce a naming schema. It has to follow the package name rules, what means that has to be at least as a domain name you control, and you can create as many subgroups as you want. Look at More information about package names.
What is a plugin in Maven?
A plugin is an extension to Maven, something used to produce your artifact (maven-jar-plugin for an example, is used to, you guess it, make a jar out of your compiled classes and resources). A dependency is a library that is needed by the application you are building, at compile and/or test and/or runtime time.
Is Maven a build manager?
Even many use Maven to resolve dependency for compilation, Maven is actually more powerful build manager, which can handle more build lifecycle s other than compilation, such as generating sources/resources, running tests, packaging and deployment.
What is artifact ID?
artifactId is the name of the jar without version. If you created it, then you can choose whatever name you want with lowercase letters and no strange symbols. If it's a third party jar, you have to take the name of the jar as it's distributed. eg. maven, commons-math.
What is a group ID in Java?
A group ID should follow Java's package name rules. This means it starts with a reversed domain name you control. For example, org.apache.maven, org.apache.commons. Maven does not enforce this rule. There are many legacy projects that do not follow this convention and instead use single word group IDs. However, it will be difficult ...
What is the difference between groupId and artifactId in Maven?
Maven uses a set of identifiers, also called coordinates, to uniquely identify a project and specify how the project artifact should be packaged: The main difference between groupId and artifactId in Maven is that the groupId specifies the id of the project group while the artifactId specifies the id of the project.
Why is Maven required?
Maven provides a solution to this issue. It helps to include all the dependencies required for the project.
What is artifact ID?
artifactId is the name of the jar without version. If you created it then you can choose whatever name you want with lowercase letters and no strange symbols. If it's a third party jar you have to take the name of the jar as it's distributed. eg. maven, commons-math.
1. Overview
In this tutorial, we'll be looking at the role of a Maven artifact classifier. Following that, we'll take a look at the various scenarios where they might be useful. Before concluding, we'll briefly discuss the Maven artifact type as well.
2. What Is a Maven Artifact Classifier?
A Maven artifact classifier is an optional and arbitrary string that gets appended to the generated artifact's name just after its version number. It distinguishes the artifacts built from the same POM but differing in content.
3. Using the Sources Classifier
We might have noticed that each Maven artifact is often accompanied by a “ -sources.jar” artifact. It contains the source code, i.e., the .java files for the main artifact. It's useful for debugging purposes.
4. Using the Javadoc Classifier
In the same vein as the sources jar use case, we've Javadoc. It contains the documentation for the main jar artifact.
5. Using the Tests Classifier
Now, let's look at a different use case that a classifier can serve. There might be various reasons we may want to get the tests jar of a module. For one, there could be certain test stubs that we might want to reuse. Let's see how we can get the tests jar independent of the main jar artifact via a classifier.
6. Using Classifiers to Support Multiple Java Versions
Earlier, we had used an arbitrary classifier to build a second jar for our maven-classifier-example-provider module. Let's now put that to a more practical use.
7. Artifact Classifier vs. Artifact Type
Before we conclude this article, let's have a brief look at artifact type. While artifact type and classifier are closely related, they are not inter-changeable. An artifact type defines the packing format of an artifact e.g. POM or jar. It also translates to the file extension in most cases. It may also have a corresponding classifier too.
