My jardesc was working great until yesterday when I converted my project to maven.
Now for some reason when I create a jar file containing code and packages: org.javacode and org.resource, I get the following folders in jar file:
org/javacode
src/org/resource
It seem to work fine for java packages but for those packages that contain image resources it creates an additional src folder at the root.
How can I fix this?
Edit 1: Here is the pom.xml

Edit 2:
Also here is the relevant part of jardesc (the gui package is correctly placed in org/concord/energy3d/gui however the images package is mistakenly placed in src/org/concord/energy3d/resources/images when jar file is created):
<javaElement handleIdentifier="=Energy3D/src<org.concord.energy3d.gui"/>
<javaElement handleIdentifier="=Energy3D/src<org.concord.energy3d.resources.images"/>
You are not following the Maven conventions.
Your sources need to be underneath: src/main/java
Your resources need to be underneath: src/main/resources
Your test sources need to be underneath: src/test/java
Your test resources need to be underneath: src/test/resources
Maven's first rule is convention over configuration. You are focusing on the configuration bit, instead of following the convention. If you don't follow the convention, the plugins will not find things where they expect them. This will lead to them not doing what you want, so I recommend you address this properly.
Also, remove this part from your pom.xml:
<sourceDirectory>src</sourceDirectory>
<resources>
<resource>
<directory>src</directory>
<excludes>
<exclude>**/*.java</exclude>
</excludes>
</resource>

I am stuck trying to compile and test a extremely simple project. It's a beginner project in order to understand how all of this works, and I am currently stucked.
My main objective is to understand how to handle resources files that are located outside of the standard folder structure.
I have a main class, with two methods. One load a resource file which is on the standard folder structure (src\main\resources). Another one load a resource which is in a custom folder, outside of the standard structure (resources).
There is one junit file that simply verify that the resource is correctly loaded.
It works fine with IntelliJ. I simply declared the resources folder as resources folders and that's it.
Now with maven ..... actually I can't even compile with gmaven-plus. Nor run the test. So I did not even bother to declare the custom folder as a resource in the pom.xml file.
I based my pom.xml file based on an existing pom we have at work and from stuff I read on the web. There's no way I can make it work.
Here is a link to a 7zip file with my project, if one could put me on the right track, I would be grateful.

The 2.4 groovy-all POMs do not include Groovy as a dependency, because they are a POM for an uber-jar, rather than a POM that describes all the Groovy module jars. Because of this, GMavenPlus is unable to find the Groovy jar to use for compilation. The <type>pom</type> works for Groovy 2.5, and 3.0, but not 2.4. So for your use case, simply delete the <type>pom</type> (or replace it with the default of <type>jar</type>). This was the way Groovy was often included back before 2.5, so the groovy-all POMs of 2.5 and 3.0 were added to ease the transition.

I am trying to create my custom class for Sesame. I have my Eclipse (Mars) project with all Sesame librarys and a new project where I created my custom class as described in this tutorial and I folloved the instructions to install it in the other project as a local maven dependency install:install-file -Dfile=C:\Users\muletto.4\workspace\eternal_jars\CustomClassTest.jar -DgroupId=com.example -DartifactId=customclasstest -Dversion=0.1 -Dpackaging=jar -DgeneratePom=true but when I add the dependency to my pom.xml Eclipse id telling me that the artifact for my customclasstest is missing... and when I try to attache the source to if it is telling me that my jar is not correct. So my question is: How do I create a correct jar and what should be the content of it. Or maybe I am installing it in a wrong way? I tried searching but didn't found anything diffrent than the official instructions and I run out off ideas... Any help will be appreciated.

Gson is available in maven, so you can just add a dependency, see http://search.maven.org/#artifactdetails|com.google.code.gson|gson|2.2.4|jar, it has the snippet you need for your pom.
If mnist-tools isn't in a maven repo anywhere, you can add it to your local repo using mvn install-file.
Your structure probably looks like it would work (you tell us, does it?), but unless there's a good reason to change it, stick with the default structure maven uses. I.e. src/main/java, src/main/resources, src/test/java etc. If I add more I usually try to keep them in the same structure e.g. src/main/scripts
I have a multi-module project, where each module is packaged as an OSGi bundle using the Apache Felix maven-bundle-plugin. The whole project is built using a parent POM that lists the above-mentioned modules. Some modules contain configuration resources (e.g. .properties files) that should not be jarred inside the bundles for deployment but rather externalized in a dedicated config folder. My goal is to create a distribution folder (possibly, a zip file) that would look something like this:
my-app-distribution
/bundles
module1-bundle.jar
module2-bundle.jar
etc.
/conf
external1.properties
external2.properties
etc.
where the properties files under the /conf directory are hand-picked files from the individual modules' /target folders. The reason the .properties files need to be picked up from the target folders vs. the src folders is that I am using Maven resource filtering, and the source property files contain ${..} placeholders for environment-specific values. Those placeholders are properly resolved during the build process - per build profiles - and the target/ folders contain actual environment-specific values.
I've done such distribution file manipulations many times - for distributions with executable JARs, etc. In this case I wanted to use the "moduleSets" configuration of the assembly descriptor - it is easy to pull all binaries/jars into a single distribution folder using moduleSet/binary descriptor. It is also easy to exclude certain files from being packaged into an OSGi bundle - in the maven-bundle-plugin. The only issue I am stuck with is creating the /conf distribution folder and collecting the necessary properties files there. I have tried to use "fileSets" inside the "moduleSet/sources" descriptor to include only specific files from **/target of each module, but that didn't seem to work.
Anyone have a suggestion/advice? There's got to be an easy way. Or should I not use at all?
Thanks,
CV
#PetrKozelka I am not sure that extracting configuration files specific to different bundles into a separate module is a good idea. The whole point of OSGi is for bundles to be independent and potentially reusable - both in development and distributions. It only makes sense that - in the source code - the functionality implementation and related configuration files are grouped together. For a particular distribution though I might need to extract some of the files - if there is a requirement for admins to have control of certain parameters. That may be different for a different distribution/application. The assembly configuration may change, but the bundles/sources would stay the same. Also, each bundle may potentially be developed and used separately, not all bundles have to always be part of the same uber project - as you seem to assume. What you are suggesting seems to fall into the same old category of packaging enterprise applications by the type of artifacts (e.g. "model", "services", "dataaccess", "config" etc.), not by functional domain/features. Such approach works ok within a single application/project, but fails on the enterprise level where there is often a need to reuse subsets of vertical components (split by functional domains).
To your point of being dependent on the file layout in the modules, I agree that there should be no such dependency. Files could be hand-picked by their explicit name or naming convention - per very specific distro requirements. (Which is exactly the case I am facing.)
I have actually figured out how to do it more or less elegantly. Posting the solution below in case someone else is looking to solve a similar problem.
SUMMARY
I am using the maven-assembly-plugin to extract the binaries (bundle JARs) from the individual modules and package them in the <my-distribution-folder>/bundles directory. In each module where some resource files should be externalized, I consolidate such files under the /src/main/resources/external directory, and use maven-resources-plugin to copy those resources during the packaging phase to the auto-generated directory in my dedicated distribution module that contains the assembly.xml descriptor file and is also built as part of the top project. I use maven-clean-plugin in the parent POM to clear the contents of the distribution staging directory during the CLEAN phase of the top-level project build.
MAVEN CONFIGURATION
Inside each bundle's module POM that contains resources that need to be externalized I add the following resource management configuration:
<build>

</instructions>
</configuration>
</plugin>
</plugins>
</build>
where externalizableResourcesStageDir is a property defined in the top/parent POM. In the project, I include a special distribution module with the following structure:
distribution
/ext-resources (target auto-generated dir for external resources from modules)
/src
/assemble
assembly.xml (assembly descriptor)
The assembly.xml file looks like this:

The parent POM would list all the bundle modules, plus the distribution module and also define the assembly plugin:

NOTE: We've also made sure that the externalized resource files are excluded from being packaged inside the individual bundle JARs (see the resources section of the module POM.) The resulting unzipped distribution will look like this:

<groupId>com.googlecode.flyway</groupId>

<url>jdbc:mysql://127.0.0.1:3306/db_abc</url>
<user>db_user</user>
<sqlMigrationPrefix>V</sqlMigrationPrefix>
</configuration>
</plugin>
I don't want to mention driver, url and user here. I already have a abc.property on src/main/resources. How can use that file here?
Have a look at the properties-maven-plugin. It allows you to read properties from a file to then use them in your pom.
Add the following plugin defintion:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>properties-maven-plugin</artifactId>
<version>1.0.0</version>
<executions>
<execution>
<phase>initialize</phase>
<goals>
<goal>read-project-properties</goal>
</goals>
<configuration>
<files>
<file>src/main/resources/abc.properties</file>
</files>
</configuration>
</execution>
</executions>
</plugin>
If abc.properties contains:
jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://127.0.0.1:3306/db_ab
jdbc.user = db_user
You can then use the properties as follows:
<!-- language: xml -->
<driver>${jdbc.driver}</driver>
<url>${jdbc.url}</url>
<user>${jdbc.user}</user>
in version 3.0 you have to use configFile like :
<configFile>src/main/resources/db/config/flyway.properties</configFile>
In my opinion, the best and the most flexible approach is to:
a) use profiles and filtering - keep all configuration properties for specific profile (development, test, etc.), e.g. in development.properties:
jdbc.url=jdbc:mysql://127.0.0.1:3306/testdb?useSSL=false
jdbc.user=testuser
jdbc.password=testpass
jdbc.driver=com.mysql.jdbc.Driver
Then, in your pom file (possibly in root pom) define a profile, e.g:
...
<profiles>
<profile>
<id>development</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<build>
<filters>
<filter>../filters/development.properties</filter>
</filters>
</build>
...
here you can see that development profile is activated by default. If you want to use another profile set it with
-p [profile-id]
b) set flyway.properties with filtered values - your flyway.properties should sit e.g. in src/main/resources and the values should be used from the parameters defined in the profile properties file:
flyway.driver = ${jdbc.driver}
flyway.url = ${jdbc.url}
flyway.user = ${jdbc.user}
flyway.password = ${jdbc.password}
c) reference flyway.properties from build directory - use simple plugin configuration (I really like clean poms):
...
<build>
<resources>
<!-- This way we instruct maven to inject values from filters into the resources -->
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
</resource>
</resources>
<plugins>
<plugin>
<groupId>org.flywaydb</groupId>
<artifactId>flyway-maven-plugin</artifactId>
<configuration>
<configFile>${project.build.directory}/classes/flyway.properties</configFile>
<locations>
<location>classpath:migration/mysql</location>
</locations>
</configuration>
</plugin>
</plugins>
</build>
...
Don't forget to enable filtering in resources as shown in many examples here. My flyway-maven-plugin version is 3.2.1 and it is managed in pluginManagement in parent pom, therefore version is not visible here. I also use explicit sql scripts with locations configuration.
There are several ways to deal with this. One approach is to do it the other way around.
That means that the properties to use are saved as properties inside the pom.xml and that the file abc.properties only has placeholders that will be filled in at build time.
I will show you how it can be configured.
This is what the pom.xml will look like:

And this will be your src/main/resources/abc.properties (use the key names of your choice):
jdbcDriver = ${jdbc.driver}
jdbcUrl = ${jdbc.url}
jdbcUser = ${jdbc.user}
After the build the target/classes/abc.properties will look like this:
jdbcDriver = com.mysql.jdbc.Driver
jdbcUrl = jdbc:mysql://127.0.0.1:3306/db_abc
jdbcUser = db_user
As stated this is only one of several ways to do it. It might not suit your exact needs but it could.
Garry,
there is one more way not to place database connection parameters to your pom-file. In particular, one can add them to settings.xml file in .m2 sub-folder of the user's folder [1]. The benefit is that the db paraneters do not live in the project folder and are not transmitted to the repository, so each developer may use her own settings.
The example of the settings file could look like the example below.
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
<profiles>
<profile>
<id>fw</id>
<properties>
<flyway.url>jdbc:oracle:thin:#//localhost:1521/xe</flyway.url>
<flyway.user>Your login</flyway.user>
<flyway.password>Your password</flyway.password>
</properties>
</profile>
</profiles>
<activeProfiles>
<activeProfile>fw</activeProfile>
</activeProfiles>
</settings>
After that your can modify your pom-file according to the following snippet.
<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"

In the example above Oracle's driver is used, but you can replace it with the required one.
To print current settings execute the following.
mvn help:effective-settings
In version 3.x you have configFile option
By default- flyway.properties in the same directory as the project POM.
You can add external property file in configuration section of pom or can be pass when running maven goal example-
command line-
mvn <goal> -Dflyway.configFile=myConfig.properties
Pom file-
