Paquetes principales de Java
JVM
Fedora permite que múltiples Java Virtual Machines(Máquinas Virtuales Java) (JVMs) sean empaquetadas independientemente. Los paquetes Java no deberían depender directamente de ninguna JVM en particular, sino que requiere de uno de los tres paquetes JVM virtuales dependiendo de la funcionalidad que se requiera.
java-headless
-
This package provides a working Java Runtime Environment (JRE) with some functionality disabled. Graphics and audio support may be unavailable in this case.
java-headless
provides functionality that is enough for most of packages and avoids pulling in a number of graphics and audio libraries as dependencies. Requirement onjava-headless
is appropriate for most of Java packages. java
-
Incluye la misma funcionalidad base que
java-headless
, pero también implementa subsistemas de audio y gráficos. Los paquetes deberían requerirjava
si necesitan alguna funcionalidad de estos subsistemas, por ejemplo la creación de .GUI (Interfaz Gráfica de Usuario) usando la librería AWT (Conjunto de Herramientas de X Window). java-devel
-
Provides full Java Development Kit (JDK). In most cases only packages related to Java development should have runtime dependencies on
java-devel
. Runtime packages should requirejava-headless
orjava
. Some packages not strictly related to java development need access to libraries included with JDK, but not with JRE (for exampletools.jar
). That is one of few cases where requiringjava-devel
may be necessary.
Los paquetes que requieren una versión mínima estándar de Java pueden añadir dependencias versionadas en uno de los paquetes virtuales que proporcionan entorno Java . Por ejemplo si paquetes que dependen de la funcionalidad de JDK 8 pueden requerir java-headless >= 1:1.8.0
.

Java Packages Tools
Java Packages Tools are packaged as several binary RPM packages:
maven-local
-
This package provides a complete environment which is required to build Java packages using Apache Maven build system. This includes a default system version of Java Development Kit (JDK), Maven, a number of Maven plugins commonly used to build packages, various macros and utlilty tools.
maven-local
is usually declared as build dependency of Maven packages. ivy-local
-
Analogously to
maven-local
, this package provides an environment required to build Java packages using Apache Ivy as dependency manager. javapackages-local
-
Package providing a basic environment necessary to geterate and install metadata for system artifact repository.
javapackages-tools
-
Package owning basic Java directories and providing runtime support for Java packages. The great majority of Java packages depend on
javapackages-tools
.
