Maven is a build automation tool used primarily for Java projects. Maven can also be used to build and manage projects written in C#, Ruby, Scala, and other languages.The Maven project is hosted by The Apache Software Foundation, where it was formerly part of the Jakarta Project.
An EAR file is a standard JAR file (and therefore a Zip file) with an .ear extension, with one or more entries representing the modules of the application, and a metadata directory called META-INF which contains one or more deployment descriptors. META-INF/ application.xml: This is the main deployment descriptor for the EAR. It lists all the ...
Artifacts are simply an output or collection of files (ex. JAR, WAR, DLLS, RPM etc.) and one of those files may contain metadata (e.g. POM file). Whereas packages are a single archive file in a well-defined format (ex. NuGet) that contain files appropriate for the package type (ex. DLL, PDB). [33]
An API to assemble archives (e.g., JAR, WAR, or EAR), which can then be deployed into an integration container (e.g., JBoss EmbeddedAS, GlassFish v3 Embedded, Jetty, or OpenEJB), or exported to a file, or exported to an exploded directory structure, or serialized over a network to a remote host, etc.; ShrinkWrap is the supported deployment ...
A JAR ("Java archive") file is a package file format typically used to aggregate many Java class files and associated metadata and resources (text, images, etc.) into one file for distribution. [4] JAR files are archive files that include a Java-specific manifest file. They are built on the ZIP format and typically have a .jar file extension. [5]
JAR hell – a form of dependency hell occurring in the Java Runtime Environment before build tools like Apache Maven solved this problem in 2004. [citation needed] RPM hell – a form of dependency hell occurring in the Red Hat distribution of Linux and other distributions that use RPM as a package manager. [11]
A WAR file may be digitally signed in the same way as a JAR file in order to allow others to determine where the source code came from. There are special files and directories within a WAR file: The /WEB-INF directory in the WAR file contains a file named web.xml which defines the structure of the web application. If the web application is only ...
An external XML file defines project dependencies and lists the resources necessary to build a project. Ivy then resolves and downloads resources from an artifact repository: either a private repository or one publicly available on the Internet. To some degree, it competes with Apache Maven, which also manages dependencies. However, Maven is a ...
