maven to gradle conversion - maven

I am trying to convert a maven project to gradle and is looking for a corresponding tags in gradle.
Here is the POM Snippet:
<configuration>
<configurationLocations>
<configurationDirectory>
<path>src/main/environment</path>
</configurationDirectory>
<configurationArtifact>
<groupId>com.test.aaa</groupId>
<artifactId>test1.jar</artifactId>

</configurationArtifact>
<configurationArtifact>
<groupId>com.test.bbb</groupId>
<artifactId>lib1.jar</artifactId>
<version>1.0.0</version>
</configurationArtifact>
</configurationLocations>
<eclipseBuildEnvironment>local</eclipseBuildEnvironment>
<testEnvironment>local</testEnvironment>

</configurationArtifact>
</configurationLocations>
<eclipseBuildEnvironment>local</eclipseBuildEnvironment>
<testEnvironment>local</testEnvironment>
</configuration>
</plugin>
The corresponding gradle configuration i added is as below
apply plugin: myapp-generator
buildscript {
repositories {}
dependencies {
classpath 'com.test.myapp:my-plugin:1.0.0'
}
So what I am looking up ithe corresponding script in gradle for
the node <configuration> in the POM

Maven plugins cannot be used by Gradle. Given that the POM extract is mostly about a custom plugin and its configuration, you will have to develop a matching Gradle plugin to replicate the features of the Maven plugin.

Cannot parse lifecycle mapping metadata for maven project...Cause: Unrecognised tag: 'version'

I am trying to get jacoco to work in the Jenkins build of a Maven project with four modules. It was working locally in eclipse when I ran the Maven build with jacoco:prepare-agent test jacoco:report. When I tried to add the goals to my Jenkins configuration, for one module the error
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-ear-plugin:2.9.1:ear (default-ear) on project mymodule: Cannot copy a directory: myOthermodule/target/classes; Did you package/install myOthermodule
appeared. My call in Jenkins is clean package install -fae jacoco:prepare-agent test jacoco:report.
So I tried to move the goal exeution from Jenkins to the pom and added
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>${jacoco-maven-plugin.version}</version>
<executions>
<execution>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
</executions>
</plugin>
to the project's pom.xml. As a result the Error

appeared in all four modules (line 6 contains <groupId>*myproject*</groupId>).
Then I tried to add

to the project's pom.xml, and the error dissolved, but then the error

I checked that I used the version tags correctly (not using a range with a version tag or vice versa)
Does anyone have an idea how to solve this?

Using cargo maven plugin to start the server without artifact deployment

I'm trying to use the cargo maven plugin just to start a JBoss AS 7 server from maven, without executing any deployments.
I'm able to start the server but as I can read in cargo pluging documentation the goals cargo:run and cargo:start will deploy automatically the current project if project's packaging is Java EE (WAR, EAR, etc.) and if I'm not using deployable sections in the plugin configuration.
This is my simple cargo plugin section in the pom file:
<plugins>
...
<plugin>
<groupId>org.codehaus.cargo</groupId>
<artifactId>cargo-maven2-plugin</artifactId>
<version>1.4.13</version>
<configuration>
<!-- Container configuration -->
<container>
<containerId>jboss73x</containerId>
<home>${jboss-as.home}</home>
</container>
</configuration>
</plugin>
...
</plugins>
Since I'm not using deployables and the project packaging is war, cargo automatically deploys my project when the server starts.
I would like use the goal cargo:run just to start my local server without deploy any project artifacts.
Is it possible with the cargo maven plugin? Any idea or alternative?
I think that it might not be possible to ask the plugin not to deploy the project in which it is configured, when you are in the case of a deployable archive project.
But what you could do is creating a pom project, with no source in it just the pom.xml, and run your cargo plugin in that project.
My example below starts and stops the cargo plugin when I run the goal install on it :
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<version>0.0.1-SNAPSHOT</version>
<packaging>pom</packaging>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.cargo</groupId>
<artifactId>cargo-maven2-plugin</artifactId>
<executions>

</executions>
<configuration>
<container>
<type>embedded</type>

</configuration>
</plugin>
</plugins>
</build>
</project>
Yes Yersan, it is possible to start the server without self built artifact deployment. It can be achieved by adding an empty <deployer /> element on the <configuration> tag of the project.
I found the info at the cargo plugin reference site. In addition, I have tested the configuration in my local project to confirm it works.

Unpack an EAR file using maven

I have an EAR file from some build. I want to extract the contents of this EAR file into another folder. I am confused how to do this. I have looked and tried
http://maven.apache.org/plugins/maven-ear-plugin/
and
http://maven.apache.org/plugins/maven-dependency-plugin/usage.html
but either maven is unable to find the file or it has dependency issues.
Since I am new to maven I don not understand how to set these plugins up.
I got the following error on using the below plugin.
Failure to find ECM:ECM:ear:1.0 in http://repo.maven.apache.org/maven2 was cached in the local repository
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.6</version>

<phase>package</phase>
<goals>
<goal>unpack</goal>
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>ECM</groupId>
<artifactId>ECM</artifactId>
<version>1.0</version>
<type>ear</type>
</artifactItem>
</artifactItems>
<outputDirectory>${project.build.directory}/earoutput</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
You can do it using dependency:unpack-dependencies. I just modify my answer because according to your comments, your ear is generated by some other build. If you do not have an Enterprise repository that you can deploy your ear artifact, you have to use "system" scope, but please note that it is usually discouraged.
Add below dependency to your pom.xml
<dependency>
<groupId>ECM</groupId>
<artifactId>ECM</artifactId>
<version>1.0</version>
<type>ear</type>
<scope>system</scope>
<systemPath>/path/to/your/abc.ear</systemPath>
</dependency>
Add the below plugin to your postBuild module pom.xml
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.6</version>
<executions>
<execution>
<id>unpack</id>
<phase>package</phase>
<goals>
<goal>unpack-dependencies</goal>
</goals>
<configuration>
<includeArtifactIds>ECM</includeArtifactIds>
<outputDirectory>${project.build.directory}/earoutput</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
Have you looked at this example of Maven EAR plugin for Unpacking a module yet?
The Maven Dependency Plugin and its unpack goal can do this.
Sample configuration:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.6</version>
<executions>
<execution>
<id>unpack</id>
<phase>package</phase>
<goals>
<goal>unpack</goal>
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>myear</groupId>
<artifactId>myear</artifactId>
<version>1.0</version>
<type>ear</type>
</artifactItem>
</artifactItems>
<outputDirectory>${project.build.directory}/earoutput</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
This takes the 'myear.ear' artifact and extracts it to the 'target/earoutput' directory. This also works with JARs, WARs and any other zip-like file. The phase this executes under is 'package' - this may be too late if you need to use these resources in other parts of the build. Change the phase to something earlier such as 'generate-resources' if needed.
You mentioned that you already tried using the dependency plugin. Is the EAR file from another Maven project, and has it been installed in the local Maven repository? If it still doesn't work post the plugin configuration you tried to use.
(edit: update information on dependencies and local repository)
For this to work, your EAR file needs to be put into your local Maven repository (this is just a directory on your disk). But if other people need to build your project as well, you have a few options:
import the EAR into your local repository, and also deploy to a remote repository so everyone can get it (recommended, but requires you to set up a corporate Maven repository)
give the EAR to everyone and have them put it into their local repository using a couple of Maven commands (might be OK for a few developers, less overhead than setting up a whole repository server)
check the dependent EAR into source control under your project and unpack it (not the recommended way of doing things) in a goal in your project
Importing into your local repository is easy. It's very similar to these instructions.
Use the following command:
mvn install:install-file -Dfile=<path-to-EAR-file-on-local-filesystem> -DgroupId=myear
-DartifactId=myear -Dversion=1.0 -Dpackaging=ear
(modify path, groupId, artifactId and version as needed)
Group ID and artifact ID are there simply to uniquely identify artifacts.
Once you install this in the local repository, the dependency plugin should work and find the artifact.

XML maven artifact not on classpath

I have some external configuration (XML files) that are installed in Maven. I need to have them on my test classpath but they aren't appearing.
They must stay as XML, I cannot package them inside a Jar - but I am willing to try anything else for this, custom plugin etc.
(Please don't inform me that Maven is only for Jars - that's simply not true (and if you provide a reference refuting that I can assure you it's out-of-date/misinformation).
The dependencies are specified thus:
<dependency>
<groupId>some.group</groupId>
<artifactId>some.artifact</artifactId>
<version>${project.version}</version>
<scope>test</scope>
<type>xml</type>
<classifier>some.classifier</classifier>
</dependency>
These XML artifacts have been created by the build-helper plugin (so there's no 1-2-1 with their project's POM).
My only current hacky solution is to, check for the M2_HOME property and load the files from there (as they're defined as dependencies Maven does pull them down) - but I'm not happy with this.
EDIT: The next best hack is probably to use the maven-dependency-plugin to copy these to the output directory (target/classes). If my config is fine for Jars then this smells like a Maven bug.
EDIT 2: #khmarbaise asked for the build-helper-plugin config:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<executions>
<execution>
<id>attach-artifacts</id>
<phase>package</phase>
<goals>
<goal>attach-artifact</goal>
</goals>
<configuration>
<artifacts>
<artifact>
<file>target/classes/ddl-seed.xml</file>
<type>xml</type>
<classifier>ddl-seed</classifier>
</artifact>
<!-- ... more definitions -->
This generates the correct maven-metadata-local.xml data for all the XML artifacts.
Unfortunately I can find no way of forcing maven to add the test dependency specified to the test classpath, other than this stinky hack of copying it to a directory on the test classpath.
This seems the quickest way (it's for a test dependency), avoiding any JAR creation.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>unpack</id>

yuicompressor plugin execution not covered in m2e

After a long search for a JavaScript compressor I could use in Maven, I finally found one:
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>yuicompressor-maven-plugin</artifactId>
<version>1.1</version>
<executions>
<execution>
<goals>
<goal>compress</goal>
</goals>
</execution>
</executions>
<configuration>
<jswarn>false</jswarn>
</configuration>
</plugin>
Now in the latest version of m2e in Eclipse, I get the following error:
Plugin execution not covered by lifecycle configuration: net.alchim31.maven:yuicompressor-maven-plugin:1.1:compress (execution: default, phase: process-resources)
Lovely. I don't get it---it's just a plugin. Why can't m2e simply call any old plugin I have? What's wrong with this one? How do I fix this?
See http://wiki.eclipse.org/M2E_plugin_execution_not_covered
To solve some long-standing issues,
m2e 1.0 requires explicit instructions
what to do with all Maven plugins
bound to "interesting" phases (see M2E
interesting lifecycle phases) of
project build lifecycle. We call these
instructions "project build lifecycle
mapping" or simply "lifecycle mapping"
because they define how m2e maps
information from project pom.xml file
to Eclipse workspace project
configuration and behaviour during
Eclipse workspace build.
Project build lifecycle mapping
configuration can be specified in
project pom.xml, contributed by
Eclipse plugins and there is also
default configuration for some
commonly used Maven plugins shipped
with m2e. We call these "lifecycle
mapping metadata sources". m2e will
create error marker like below for all
plugin executions that do not have
lifecycle mapping in any of the
mapping metadata sources.
Plugin execution not covered by lifecycle configuration:
org.apache.maven.plugins:maven-antrun-plugin:1.3:run
(execution: generate-sources-input, phase: generate-sources)
m2e matches plugin
executions to actions using
combination of plugin groupId,
artifactId, version range and goal.
There are three basic actions that m2e
can be instructed to do with a plugin
execution -- ignore, execute and
delegate to a project configurator.
If you search around, you'll find a lot of links showing you how to suppress that error. However, I found a way to actually have the default Maven Project Builder execute these plugins within eclipse. The key is to change the <ignore> you find in many suggestions to <execute>. After adding this to my pom, I have automatic aggregation, compression, and deployment off of just a user saving a javascript resource:
<pluginManagement>
<plugins>
<plugin>
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>

</pluginExecutionFilter>
<action>
<execute></execute>
</action>
</pluginExecution>
</pluginExecutions>

Maybe you have to provide the id and phase?

At least i don't get that message with this configuration.
