Module System API


Module System API
org.openide.modules NetBeans is capable of being extended by pluggable modules providing additional functionality.


What is New (see all changes)?

Use Cases

How a classpath of my module is constructed?
The NetBeans is defacto a container that manages individual module's lifecycle and other runtime aspects. One of the important things is that it creates a runtime classpath for provided modules based on dependencies they specify in their manifests. The overview of the runtime infrastructure is a good starting place for everyone who wishes to learn more about the NetBeans runtime container behaviour.

FileObjects created on XML layer now support a new attribute removeWritables returning an instance of Callable which removes the local writable version of the given FileObject thus reverting the folder or file to its initial state as defined in XML layers. Please note that is not possible to reset FileObject's attributes.

Classpath appended to the system class loader. Used for automated testing infrastructure.


By default true, may be turned off to disable manifest caching.


Patch directories or JARs to add to the class loader for a module, besides patches/MODULE-CODE-NAME-BASE/*.jar.


If true, all module classes are forcibly loaded at startup, to help detect possible linkage errors.


Disables automatic module dependency upgrades.


If set to 0, enables logging for the module system.


Disabled automatic transitive class loader dependencies for old modules.


Avoids text messaging (other than ErrorManager logging) to the console from the module system.


Suppresses checks to ensure that module section classes are actually loaded from the module itself.

Suppress security checks in the VM, even from "untrusted" code.


Prints messages when resources or classes are loaded from JARs.


Used to control the XML layer cache mechanism. Value may be a fully-qualified class name to load as a manager (implement org.netbeans.core.projects.cache.LayerCacheManager), or - to disable caching and always parse the XML layers directly. Current default is to use a binary cache manager.
