By using the plugin

       
           org.apache.cxf
           cxf-codegen-plugin

SOLUTION:
To exclude the dom4j dependency!

mvn dependency:tree > tree.txt

To find where dom4j comes.

Exclude the dependency:

     
        found_dependency
        found_dependency
        test
        
           
              dom4j
              dom4j
           
        
     

And fuck off the "pull-parser".
Add it to the exclusions.

It works pretty good!!!

Documentation here

What Gets Drawn

-all

Same as -attributes -operations -visibility -types -enumerations -enumconstants

-attributes

Show class attributes (Java fields)

-commentname

Name the element using the text in the javadoc comment, instead of the name of its class.

-constructors

Show a class's constructors

-enumconstants

When showing enumerations, also show the values they can take.

-enumerations

Show enumarations as separate stereotyped primitive types.

-hide

Specify entities to hide from the graph. Matching is done using a non-anchored regular match. For instance, "-hide (Big|\.)Widget" would hide "com.foo.widgets.Widget" and "com.foo.widgets.BigWidget". Can also be used without arguments, in this case it will hide everything (useful in the context of views to selectively unhide some portions of the graph, see the view chapter for further details).

-operations

Show class operations (Java methods)

-qualify

Produce fully-qualified class names.

-types

Add type information to attributes and operations

-view

Specify the fully qualified name of a class that contains a view definition. Only the class diagram specified by this view will be generated.
See the views chapter for more details.

-views

Generate a class diagram for every view found in the source path.

-visibility

Adorn class elements according to their visibility (private, public, protected, package)

Relationship Inference

-collpackages

Specify the classes that will be treated as containers for one to many relationships when inference is enabled. Matching is done using a non-anchored regular match. Empty by default.

-inferdep

Try to automatically infer dependencies between classes by inspecting methods and fields. See the class diagram inference chapter for more details. Disabled by default.

-inferdepinpackage

Enable or disable dependency inference among classes in the same package. This option is disabled by default, because classes in the same package are supposed to be related anyway, and also because there's no working mechanism to actually detect all of these dependencies since imports are not required to use classes in the same package.

-inferdepvis

Specifies the lowest visibility level of elements used to infer dependencies among classes. Possible values are private, package, protected, public, in this order. The default value is private. Use higher levels to limit the number of inferred dependencies.

-inferrel

Try to automatically infer relationships between classes by inspecting field values. See the class diagram inference chapter for further details. Disabled by default.

-inferreltype

The type of relationship inferred when -inferrel is activated. Defaults to "navassoc" (see the class modelling chapter for a list of relationship types).

-useimports

Will also use imports to infer dependencies. Disabled by default, since it does not work properly if there are multiple classes in the same source file (will add dependencies to every class in the source file).

Антран плагины: нельзя два в одном и как проверить проперть

Если вы напишете в поме два плагина антран, то будет валидный только второй.

Вот пример:

===\/=====================================
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<id>000</id>
<phase>clean</phase>
<configuration>
<tasks>
<echo>=== ECHO === [${project.build.directory}] ===</echo>
<echo>=== ECHO === 000 ===</echo>
<echo>=== ECHO === 000 ===</echo>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<id>0</id>
<phase>clean</phase>
<configuration>
<tasks>
<echo>=== ECHO === [${project.build.directory}] ===</echo>
<echo>=== ECHO === 0 ===</echo>
<echo>=== ECHO === 0 ===</echo>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
===/\=====================================

Результат работы:

[INFO] [clean:clean]
[INFO] [antrun:run {execution: 0}]
[INFO] Executing tasks
[echo] === ECHO === [/home/alexey/java/eXoProjects/portlet-container/trunk/applications/tck-tests/target] ===
[echo] === ECHO === 0 ===
[echo] === ECHO === 0 ===
[INFO] Executed tasks


Кстати, таким образом антран плагином можно проверить наличие системной проперти при помощи ECHO!

Maven war plugin classpath and play around manifest

http://maven.apache.org/plugins/maven-war-plugin/examples/war-manifest-guide.html

Maven 2 build Lifecycle Phases

There are options for dependencies

1. The "optional" tag is "true"
goes in manifest classpath, but not included in WEB-INF/lib

2. The "scope" tag is "provided"
excluded from manifest classpath, and excluded from WEB-INF/lib

For plugin maven-war-plugin we can add options to exclude all dependencies in manifest.

  configuration
    archive
      manifest
        addClasspath false /addClasspath

How can we exclude a list of dependencies from MANIFEST file with some option for plugin configuration?
E.g.:

configuration
  excludeProjects
    junit, jmock, bcel, ehcache, xercesImpl
  /excludeProjects
  includeToWarClasspath/
/configuration

Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting and documentation from a central piece of information.

We faced problem with antrun plugin

[java] Exception in thread "main"
[java] Java Result: 1


Thats problem solved with change
<latest>1.0</latest>
<release>1.0</release>
within
maven2\repository\org\apache\maven\plugins\maven-antrun-plugin\maven-metadata-central.xml

Or, much better to point version for maven plugin within pom.xml
For example:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>

<version>1.0</version>

And, sometimes ploblem in that maven doesn't see plugins at all.
Need to point plugin repository
For example:
<pluginRepositories>
<pluginRepository>
<id>snapshot</id>
<name>Snapshot repository</name>
<url>http://snapshots.maven.codehaus.org/maven2/</url>
</pluginRepository>
</pluginRepositories>

Continuum
wiki


Continuum is a continous integration server for building Java based projects.
Continuum is a great partner to Apache Maven which will run builds on a configurable schedule. Continuum will email developers when the build is broken requesting that the culprit fix the problem. You may add a project to Continuum simply by pointing to the pom.xml in the source control system and it will magically do the rest (check out from source control, run a clean build, deploy to the integration server and run unit tests).
