sorry for the dumb question, but I'm really new to maven and I cannot find any answer (I tried, I found something, but I did not understand it ;-) )
The problem is the following:
I'm building my (eclipse) RCP APP using tycho
My plugins rely on a system property to enable a debug mode (by default it is disabled, and it is enabled by launching the program with "-Ddebug=true" as java argument)
I have some tests (packaged as fragment, as suggested everywhere)
I want that the system property is set when my tests run
How can I instruct maven to do that?
try
<plugins>
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-surefire-plugin</artifactId>
<version>${tycho-version}</version>
<configuration>
<systemProperties>
<key>value</key>
</systemProperties>
</configuration>
</plugin>
</plugins>
You should update the configuration of your test plugin within your Maven pom:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.10</version>
<configuration>
<argLine>-Ddebug=true</argLine>
</configuration>
</plugin>
</plugins>
</build>
Tycho uses surefire. You need to use the systemPropertyValues configuration element of surefire.

After successfully following this HowTo to integrate Lombok and AspectJ in a Maven build, my code doesn't compile anymore in eclipse.
There are a lot of errors everywhere due to absence of getter/setter/constructors normally generated by Lombok.
My goal is to be able to use eclipse to develop using Lombok, and after that using a mvn clean install on command line in order to build.
I tried to skip AspectJ weaving in eclipse, but without success.
Here is the profile I used to skip AspectJ:
<profile>
<id>noAspectJ</id>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<executions>
<execution>
<id>process-classes</id>
<phase>none</phase>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<compilerVersion>1.7</compilerVersion>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
</plugins>
</build>
</profile>
The best solution I found was to remove the AspectJ plugin from my Eclipse, since it don't need it there.
This way I could also avoid using a profile.
But this could probably lead to some problem if I used the JUnit tests in eclipse.
I am using BPM Suite 6 to create a git repository and shell project. I am then connecting to the git repo in my Eclipse IDE.
The Pom file created by BPM Suite web GUI includes the kie-maven-plugin. However Eclipse complains that this "Plugin execution not covered by lifecycle configuration".
From Googling this error a bit I have come to understand that this means Eclipse does not understand when to execute this plugin during Eclipse's build process. It also seems that the 'best' way of fixing this issue is to install an m2e connector for the plugin.
Does such a connector exist?
Does not directly answer the question but I found a workaround in the old user forums:
http://drools-moved.46999.n3.nabble.com/rules-users-Drool-6-0-0-Final-2-question-re-kie-maven-plugin-please-td4027117.html
The workaround is to include in your pom some extra information that tells eclipse how to deal with this plugin. If I understand this correctly, this causes Eclipse to execute the plugin only when it builds the project. This is what the workaround ends up looking like:
<build>
<plugins>
<plugin>
<groupId>org.kie</groupId>
<artifactId>kie-maven-plugin</artifactId>
<version>6.0.3-redhat-6</version>
<extensions>true</extensions>
</plugin>

This is known Eclipse limitation, as it is not so flexible with custom Maven goals. This is the design way eclipse m2 plugin chose to go. You can chose actions like ignore,
This is what Redhat suggests for maven usage:Redhat guide for Maven usage for Developers
Alternate, you can use IntelliJ what handles this just as it is expected by Maven design for usage.
I am in the process of migrating my build from Ant to Maven. The Ant build used to compile a "code generator", execute this "code generator" which produced a set of Java and C code. It then took the generated Java code and compiled it along with some additional code produce a single jar.
I have replicated this this in Maven quite easily and it works well when I run from the command line but Eclipse is complaining and is giving me an error relating to the pom file
Failure to find {group.id}:{artifact.id}:pom:1.0.0-SNAPSHOT in
http://{our internal site repository}/nexus/content/groups/public was
cached in the local repository, resolution will not be reattempted
until the update interval of snapshots has elapsed or updates are
forced
where the group.id and artifact.id are the group and artifact id of my code generator plugin
and any code that references the generated code also fails to compile.
My maven build consists of
a generator project that contains just the Java code for the code generator.
a generator-plugin project that contains just the code to wrap the generator as a Maven plugin. This is dependent upon the generator project.
an xyz project that uses the plugin to generate the code. The code ends up in the target/generated-sources/xxx folder of this project. I have configured the build-helper-maven-plugin as per Maven compile with multiple src directories to include this extra source directory.
If I manually add the generated source folder to the Eclipse build path all of the errors relating to the code not being there go away on that project but not on any downstream projects and the "Failure to find..." error listed above remains.
What puzzles me a little is that it is referring to the ...:pom:1.0.0-SNAPSHOT when in fact my generator-plugin is defined as a maven-plugin.
Is this a sensible approach?
Why am I getting a "Failure to find..." error?
Why isn't Eclipse picking up my generated-sources folders?
I should also say I have the m2e plugin and the m2e connector for build-help-maven-plugin installed in my Eclipse IDE.
It looks like a problem during the download of the lib from the repository. I already had the same error message once.
Did you take a look at your local repository?
Go to the .m2 folder and look for /nexus/content/groups/public. If the folder is there, open it and see if the lib was download correctly. If not, try to delete the folder and try to run mvn install to force the download of the lib.
At Eclipse, run Right button > Maven > Update Project too.
Are you using an local repository like Artifactory, aren't you? Also look for the lib in the repo1-cache (or similar) folder. See if the jar is there.
Are you behind any firewall or proxy?
Using eclipse Indigo3.7, this was what I found that worked good using spring 3.1.1 which does have the 3.0.6 version as well in it. Once I got the plugins setup and put into the correct area of the pom and included the argline and endorseddirs to have the java sources put out into the target/generated-sources/cxf folder then maven generated the sources ok.

I have a maven project in eclipse and have maven goals that run annotation processors to generate code. The output folder for this code is target/generated-sources/apt.
In order for Eclipse to see this generated code I need to add target/generated-sources/apt as a source folder to the Eclipse project.
However, this causes there to be an error of type "Maven Configuration Problem" saying
Project configuration is not up-to-date with pom.xml. Run project
configuration update
I think I understand why this is the case as Eclipse has a different set of source folders to Maven's set. But I need this different set, as I need Eclipse to be able to see the generated source folders...
When doing a pure Maven built, these source folders will be included in the build, by Maven.
BTW, I have upgraded to the official Eclipse release of the Maven Eclipse plugin, m2e 1.0 - what used to be m2eclipse. I'd like to see if I can find a work around/solution to this with the m2e plugin before I have to go back to the old m2eclipse version.
You need to attach the source directory with the build-helper-plugin.
Like so:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<executions>
<execution>
<id>add-source</id>
<phase>generate-sources</phase>
<goals>
<goal>add-source</goal>
</goals>
<configuration>
<sources>
<source>${project.build.directory}/generated-sources/java/</source>
</sources>
</configuration>
</execution>
</executions>
</plugin>
You will also need to:
Install the "Apt M2E Connector" from the Eclipse Marketplace.
To do so click the error in the Overview tab of your pom.xml and select "Discover".
Ensure there are no plugin execution filters for the build-helper-maven-plugin (see https://www.eclipse.org/m2e/documentation/m2e-execution-not-covered.html)
Right-click the Error message:
Project configuration is not up-to-date with pom.xml Run project
configuration update
in the Problems View and select Quick Fix and click Finish to select the default Update project configuration. This fixes it.
After switching to new versions of m2e/maven/apt,... i had builderrors because of the duplicated files, caused by the added buildpath by the buildhelper, so i needed to remove the "apt-generated"-Folders from the buildhelper.
To fix the Problem in Eclipse, not adding the "apt-generated"-folder via Update Maven Configuration in M2E, i've written a M2E Plugin to fix this problem. It adds the outputDirectories configured in the maven-apt-plugin to the buildpath of the Project.
https://apt-m2e.googlecode.com
In m2e 1.0 the handling of Maven plugins has changed. You might be lacking a specific m2e extension for your code generating plugin. Here is all the documentation I managed to find.
This bug report may also be relevant.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=350081
request on CXF JIRA (see 1) to add lifecycle mappings in the cxf-codegen-plugin itself. This would require m2e 1.1 but I believe it is better approach than having connectors built outside of cxf project, assuming that lifecycle mapping API would change less frequently than cxf-codegen-plugin and cxf.
You can also use the buildhelper m2e connector available in the discovery catalog. I'm using Eclipse 3.7
Eclipse Java EE IDE for Web Developers.
Version: Juno Service Release 1
mvn archetype:generate \
-DarchetypeGroupId=org.codehaus.mojo \
-DarchetypeArtifactId=gwt-maven-plugin \
-DarchetypeVersion=2.5.0
mvn clean install
work perfectly.
But in eclipse I have the same error on Asinc class.
Just press F5 on project. Fix this problem.
This was what I found that worked good using spring 3.1.1 which does have the 3.0.6 version as well in it.

In case for some reason you can't use the build helper plugin the easiest way (albeit not as convenient and somewhat tedious) I have found to deal with this is:
Separate the generated source code into its own project or sub module.
You will want to keep this project predominately closed or not imported into Eclipse when you are working on the parent project.
In the parent project that needs the generated code make sure to now depend on the generated source code project via Maven pom dependency.
When you need to update the generated code go to the generated code project and run mvn install. Now refresh the parent project by right clicking and selecting Maven->Update Project...
This generally works well for projects that use a semi static source for code generation such as SOAP WSDLs (Apache CXF) or code generated from a database (jOOQ). For APT and other AspectJ-like-code it doesn't work as well because you are editing the source frequently.
For new visitors to this question -
build helper maven plugins and m2e connectors go hand in hand. Older versions
(before 2.0) of build helpers have moved into an eclipse archive link
build helper versions archived
Pick the correct link from the list and add it as an eclipse update site. It should ask you for a bunch (seriously.. a huge bunch ) of eclipse updates . Please accept and you are good to go.
the configuration to the build helper plugin did work for us.
but be aware, that the destination folder always has to be equal to the configuration of the plugin u're using for the annotation processing itself.
for example the maven-processor-plugin uses the target folder ${project.build.directory}/generated-sources/apt as default. if you wish another destination for your generated source files you can set it by the tag as shown below.
<plugin>
<groupId>org.bsc.maven</groupId>
<artifactId>maven-processor-plugin</artifactId>
<version>2.1.1</version>
<executions>
<execution>

I am using eclipse + maven2 to build my applications.
I need to start working with clover.
My question is therefore: from your experience, what is the best way to combine these 3.
I mean, I know there is a clover plugin for eclipse, there is also a clover plugin for maven2 and of course there is maven plugin for eclipse (m2eclipse - which I am already using).
What should I use and how?
Thank you.
Under Eclipse, use the Clover Eclipse Plugin.
Under Maven, use the Maven Clover Plugin. Add a Clover Report to the site generation:
<project>
[...]
<build>
<plugins>
<plugin>
<groupId>com.atlassian.maven.plugins</groupId>
<artifactId>maven-clover2-plugin</artifactId>
<configuration>
[...]
</configuration>
<executions>
<execution>
<phase>pre-site</phase>
<goals>
<goal>instrument</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
[...]
<reporting>
<plugins>
[...]
<plugin>
<groupId>com.atlassian.maven.plugins</groupId>
<artifactId>maven-clover2-plugin</artifactId>
<configuration>
[...]
</configuration>
</plugin>
</plugins>
</reporting>
[...]
Optionally, you can check for a test coverage percentage and fail the build in case of non-compliance:
<build>
<plugins>
<plugin>
<groupId>com.atlassian.maven.plugins</groupId>
<artifactId>maven-clover2-plugin</artifactId>
<configuration>
<targetPercentage>80%</targetPercentage>
</configuration>
<executions>
<execution>
<phase>verify</phase>
<goals>
<goal>instrument</goal>
<goal>check</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
The maven build remains the master. Run it using your preferred method (command line or m2eclipse).
I'm using the clover-report along with the automated site generation by maven. For that you just have to add the clover plugin to your POMs reporting section as describes here. That way you can also get a historical report about your code coverage.
Calling/starting the maven process is done via the m2eclipse plugin and that's it. But you could also use all 3 plugins. So for example install the clover plugin for eclipse so that you don't have to generate the whole site again and again when you only want the code coverage (with the clover plugin for eclipse you can see the coverage right inside eclipse) and use the clover maven plugin to generate a "final" code coverage for any released piece of code. The m2eclipse plugin is not really needed for neither clover-maven nor clover-eclipse but it's nice when working with eclipse and maven.
