I have following project modules. Each of the modules have their own pom.xml . Now I want to generate a parent POM (for existing modules like below) . Is there a way to do that? I know there is a way we can do if we are creating brand new project but my need here is I already have a project structure.
project-module-1
project-module-2
project-module-3
project-module-4
Thank you for your help
You need revising your exising project a little, it is not too hard.
Your project structure like this
parent pom.xml

How can I include a sibling module as a test dependency for my spring boot tests in maven?
I have a little multi-module maven project with a spring boot web app (querying-api ), a common library (domain-definitions), and an initializing script (database-loader).
I'm writing test cases in my querying-api module to test my API, and I would like to run my database-loader service before the tests begin to load the database with predefined test data, simultaneously testing that the loader still works. However I'm getting the following error when running mvn clean package:
[ERROR] Failed to execute goal on project querying-api: Could not resolve dependencies for project com.my.little.package:querying-api:jar:1.0.0: Failure to find com.my.little.package:database-loader:jar:1.0.0 in http://mycompanysnexusrepo.com/nexus/content/repositories/EAJAVA/ was cached in the local repository, resolution will not be reattempted until the update interval of EAJAVA has elapsed or updates are forced -> [Help 1]
The tests have no problem referencing the common domain-definitions library...

This might be because of the library jar not found in the local repository. You need to first execute :
mvn clean install.
This will install the lib jar in your local repository and maven can easily find it when you execute package goal.
Explained here: How are "mvn clean package" and "mvn clean install" different?
Furthermore, if you are using the sibling module only in tests then you can define the scope as test in dependency.
<dependency>
<groupId>com.my.little.package</groupId>
<artifactId>domain-definitions</artifactId>
<scope>test</scope>
</dependency>
I wanted to create a "Common" module in order to store my common methods in it for my Client and Server to use. To do so I simply created the module, and added the following to my sub-modules poms:
<dependency>
<groupId>com.christopher.kade</groupId>
<artifactId>common</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
Additionally, I don't want my common module to generate a .jar file, I just want my other modules to access its content, so here is its pom:
<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">

What should I change in order to make this build work? So far it builds 3 .jars and I can't access my common methods in my client or server module.
I'm a beginner trying to access elasticsearch through JAVA with eclipse, but after following the instructions available at this guide , eclipse is not able to import packages like org.elasticsearch.node.* and I haven't been able to continue.
This is my first time with Maven, and the configurations might be wrong.
This is my pom.xml file:
<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">

<groupId>org.elasticsearch</groupId>

<packaging>jar</packaging>

</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>
I can access elasticsearch through a terminal or browser, but not with eclipse. What step I am missing?
You haven't defined es.version in your properties section. mvn install should have thrown errors because it can't download elasticsearch dependencies. I think following change to your pom would work.
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<es.version>0.90.3</es.version>
</properties>
Here is the pom.xml in my eclipse Maven project. It works. Just for you reference.
