Answer:
NetBeans Maven support recognizes special file(s) that can be placed
next to a pom.xml. These files contain description of
bindings between NetBeans UI actions (compile, run, debug, etc.) and
the actual Maven goals to execute.
Primary name of the file is nbactions.xml. In
addition to this, there can be other nbactions-profile.xml
where profile is the name of a Maven profile. These files are
active when such profile is choosen as a selected
project configuration. The sample format of the file follows:
<?xml version="1.0" encoding="UTF-8"?>
<actions>
<action>
<actionName>run</actionName>
<goals>
<goal>process-classes</goal>
<goal>exec:java</goal>
</goals>
</action>
<action>
<actionName>debug</actionName>
<goals>
<goal>process-classes</goal>
<goal>exec:java</goal>
</goals>
<properties>
<jpda.listen>maven</jpda.listen>
</properties>
</action>
<action>
<!-- this action is shown in 'Custom' submenu of project popup menu -->
<actionName>CUSTOM-bck2brwsr-show</actionName>
<displayName>Run in a Browser</displayName>
<goals>
<goal>clean</goal>
<goal>package</goal>
<goal>bck2brwsr:show</goal>
</goals>
<activatedProfiles>
<activatedProfile>bck2brwsr</activatedProfile>
</activatedProfiles>
<properties>
<skipTests>true</skipTests>
</properties>
</action>
<!-- the profiles section is only useful in nbactions.xml
and gets activated when profile of given id is choosen in the UI
-->
<profiles>
<profile>
<id>bck2brwsr</id>
<!-- changes meaning of run action when bck2brwsr profile
is selected
-->
<actions>
<action>
<actionName>run</actionName>
<displayName>Run in a Browser</displayName>
<goals>
<goal>clean</goal>
<goal>package</goal>
<goal>bck2brwsr:show</goal>
</goals>
<activatedProfiles>
<activatedProfile>bck2brwsr</activatedProfile>
</activatedProfiles>
<properties>
<skipTests>true</skipTests>
</properties>
</action>
</actions>
</profile>
</profiles>
</actions>
If an action is not found in currently selected <profile> section, the system fallbacks to the main list of actions. In the previous example, the debug action would be taken from main list for all the profiles.
jpda.attach -One can define following code in nbactions.xml file to start a process during goal execution and attach a debugger to it once the execution is over. Here is an example using enhancement in the Maven Android plugin:
<action>
<actionName>debug</actionName>
<goals>
<goal>clean</goal>
<goal>package</goal>
<goal>android:deploy</goal>
<goal>android:run</goal>
</goals>
<properties>
<skipTests>true</skipTests>
<android.run.debug>${jpda.attach.port}</android.run.debug>
<jpda.attach>true</jpda.attach>
</properties>
</action>
Value of jpda.attach property can either be true
and in such case the IDE finds an empty port and sets values of
jpda.attach.port and jpda.attach.address
properties accordingly, or it can be directly specified
address:port or just port number to connect to.
One can define following code in nbactions.xml file to start a process during goal execution and attach a debugger to it when the external process prints a text indicating it's ready for attaching debugger. One example is debugging applications using Multi-OS Engine:
<action>
<actionName>debug</actionName>
<goals>
<goal>package</goal>
<goal>moe:launch</goal>
</goals>
<properties>
<skipTests>true</skipTests>
<moe.options>debug:${jpda.attach.port}</moe.options>
<jpda.attach>true</jpda.attach>
<jpda.attach.trigger>JDWP will wait for debugger on port</jpda.attach.trigger>
</properties>
<activatedProfiles>
<activatedProfile>moe</activatedProfile>
</activatedProfiles>
</action>
Value of jpda.attach.trigger property is the expected text.
"Projects/org-netbeans-modules-maven/Customizer" folder's content is used to construct the project's customizer.
It's content is expected to be ProjectCustomizer.CompositeCategoryProvider instances.
The lookup passed to the panels contains an instance of Project and org.netbeans.modules.maven.api.customizer.ModelHandle
Please note that the latter is not part of any public APIs and you need friend dependency to make use of it.
"Projects/org-netbeans-modules-maven/Nodes" folder's content is used to construct the project's child nodes.
It's content is expected to be NodeFactory instances.
"Projects/org-netbeans-modules-maven/Lookup" folder's content is used to construct the project's additional lookup.
It's content is expected to be LookupProvider instances. Maven project provides LookupMergers
for Sources, PrivilegedTemplates, RecommendedTemplates and other classes. Implementations added by 3rd parties
will be merged into a single instance in the project's lookup.
Projects/org-netbeans-modules-maven/<packaging-type>/Lookup is added to the project's additional Lookup. The content is expected
to contain packaing-specific services and processors, for example, PrerequisitesCheckers.
In addition, Projects/org-netbeans-modules-maven/_any/Lookup defines services that act after the packaging-specific ones.
Technology-related services can be registered so they activate in a project that has configured a specific Maven plugin. Such services should
be placed in Projects/org-netbeans-modules-maven/<plugin-id>/Lookup folder. Maven core module will plug these providers in
as soon as the plugin-id appears in the POM model, and will remove them from project's Lookup when the plugin is no longer part of the project's model.
See NbMavenProject javadoc for details/examples.
"Projects/org-netbeans-modules-maven/ProjectActions",
"Projects/org-netbeans-modules-maven/DependenciesActions" and
"Projects/org-netbeans-modules-maven/DependencyActions" folders' content is used to
add item's to node popup. To main project node, Dependencies node and node for single dependency.
It's content is expected to be Action instances.
A module can disable warning for a custom lifecycle participant by creating a folder in
Projects/org-netbeans-modules-maven/LifecycleParticipant. Currently single boolean attribute,
ignoreOnModelLoad is supported, which suppresses project problem and warning about
the custom participant. The participant's code does not run after project load.
"Projects/org-netbeans-modules-maven/Archetypes" folder contains fileobjects that represent archetypes. The archetypes are defined by the following file attributes:
| groupId | mandatory | |
| artifactId | mandatory | |
| version | mandatory | |
| repository | optional | url of the archetype's repository |
| nameBundleKey | optional | key in bundle file that holds localized name |
| descriptionBundleKey | optional | key in bundle file that holds localized description |
Project API clients may place ProjectConfiguration instance in the context Lookup passed to ActionProvider.isActionEnabled() or ActionProvider.invokeAction(). If such instance is present, the action is configured according to settings in the selected configuration. If not present, the active configuration is used. See example in NbMavenProject documentation.

what others log?
Answer:
netbeans.ignore.jdk.bootclasspath
-
The maven support recognizes special tag in maven-compiler-plugin
configuration
that instructs the IDE to not put JDK libraries on a classpath. One can use:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<compilerArguments>
<bootclasspath>netbeans.ignore.jdk.bootclasspath</bootclasspath>
</compilerArguments>
</configuration>
</plugin>
section in pom.xml to suppress the JDK libraries.
org.netbeans.modules.maven.execute.AbstractOutputHandler.SLEEP_DELAY - A system property can be used to change the default indexing sleep delay during builds, in case reparsing starts too soon (wasting CPU) or too late (impeding editing).
org.netbeans.modules.maven.options.DEFAULT_REUSE_OUTPUT
-
Brand the DEFAULT_REUSE_OUTPUT key in a
org.netbeans.modules.maven.options.Bundle file
with one of the values true or false
to specify the default behavior of reusing output by your application.
Use never value, if the reuse shall never be done,
regardless of the settings value.
org.netbeans.modules.maven.api.execute.DEFAULT_COMPILE_ON_SAVE
-
Brand the DEFAULT_COMPILE_ON_SAVE key in a
org.netbeans.modules.maven.api.execute.Bundle file
with one of the values all or none
to specify the default behavior of compile on save in Maven
projects.
exec.vmArgs
-
The plugin exports Java VM parameters to be used for application execution in ${exec.vmArgs}
property that can be used in action mappings or Maven pom.xml.
exec.appArgs
-
The plugin exports application parameters to be used for application execution in ${exec.appArgs}
property that can be used in action mappings or Maven pom.xml.
NbIde.
-
Properties designed to be read only by NB IDE code, and not passed to Maven can be prefixed by this prefix.
Maven module uses such properties to communicate between services that participate on maven launch internally.
ExplicitProcessParameters
-
Project actions that execute user application (run, debug) accept additional VM and application
arguments as a series of
ExplicitProcessParameters instance(s) in the action's Lookup. See
ExplicitProcessParameters javadoc for more details.
org.netbeans.modules.maven.indexer.api.DEFAULT_CREATE_INDEX
-
Brand the DEFAULT_CREATE_INDEX key in
org.netbeans.modules.maven.indexer.api.Bundle file
with one of the values true or false
to control (usually to disable with DEFAULT_CREATE_INDEX=false)
the default behavior automatic maven index downloading.
org.netbeans.modules.maven.indexer.api.DEFAULT_UPDATE_FREQ
-
Brand the DEFAULT_UPDATE_FREQ key in
org.netbeans.modules.maven.indexer.api.Bundle file
with one of the values:
0 - once a week
1 - once a day
2 - on each startup
3 - never
DEFAULT_UPDATE_FREQ=3)
the default behavior automatic maven index downloading.
Project.org-netbeans-modules-maven.RunGoals
-
A executable-like plugin goals, that may serve in place of exec:exec may be registered here. The core implementation
will recognize such goals as exec's and will not disable app amd VM parameter configuration UI.
For an example, see MavenActionProvider.
