I'm trying to dockerize my multi module application (i'm using hexagonal architecture with Port and Adapters pattern).
Here is the structure of my application:
App structure
My root pom looks in this way:
<?xml version="1.0" encoding="UTF-8"?>

Below blog talks all about it. jib-maven-plugin is the easiest option to dockerize your app

I have just updated eclipse to Version: 2022-06 (4.24.0), and have the next exception in problems view (in pom.xml file):

No problems when generating maven artifactory.
Any idea how to avoid these error?
the solution is modify maven-war-plugin adding version 3.3.2:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.3.2</version>
<configuration>
<webXml>WebContent\WEB-INF\web.xml</webXml>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
thanks
I am trying to publish a Java library to artifactory using Jenkins. Currently, it is only publishing .jar files to artifactory. I have a binary file (.bin) that I want to publish along with the .jar files. Does anyone know what I need to insert into my POM file to make this work?
For example, I want file structure in artifactory to look like this:
test-0.1.jar
test.bin
...

The build helper maven plugin allows you to attach additional artifacts, see

under "Attach additional artifacts to your project" or

I'm compiling my project with mvn clean package, and failed with package does not exist.
The detail command:
Get the jar file target/xxxx.jar by running mvn clean package in source project.
install this jar file by running mvn install:install-file -Dfile=lib/xxxx.jar -DgroupId=com.company -DartifactId=source-package-name -Dversion=1.0.0 -Dpackaging=jar
add code to target project, which will use some functions in source project
compile target project by running mvn clean package, and it just failed with package does not exist

Ideally, you shouldn't use a Spring Boot application (something that's been repackaged) as a dependency. From the documentation:
Like a war file, a Spring Boot application is not intended to be used as a dependency. If your application contains classes that you want to share with other projects, the recommended approach is to move that code into a separate module. The separate module can then be depended upon by your application and other projects.
If the proposed solution isn't possible in your situation, the documentation goes on to describe an alternative:
If you cannot rearrange your code as recommended above, Spring Boot’s Maven and Gradle plugins must be configured to produce a separate artifact that is suitable for use as a dependency. The executable archive cannot be used as a dependency as the executable jar format packages application classes in BOOT-INF/classes. This means that they cannot be found when the executable jar is used as a dependency.
To produce the two artifacts, one that can be used as a dependency and one that is executable, a classifier must be specified. This classifier is applied to the name of the executable archive, leaving the default archive for use as dependency.
To configure a classifier of exec in Maven, the following configuration can be used:
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<classifier>exec</classifier>
</configuration>
</plugin>
</plugins>
</build>
I am facing issue in setting java compiler version for the parent-child pom files. I added maven-compiler-plugin in child pom with version 1.7 and noticed that the java version changed from default 1.5 to 1.7 for child module and the parent project is still with 1.5. Then, I moved the compiler plugin from child pom to parent pom. Expected that the compiler version will be changed to 1.7 for both parent and child maven modules. But strangely no changes observed, the child module is still with 1.7 and the parent project is 1.5. I performed 'maven- > update project' from eclipse IDE. but no use. FYI : Building the parent-child projects is working fine with no issues. Any help? Here are my parent and child POMs

In the parent you need to define it in <pluginManagement/> rather than <plugins/>
https://maven.apache.org/pom.html#Plugin_Management
pluginManagement: is an element that is seen along side plugins.
Plugin Management contains plugin elements in much the same way,
except that rather than configuring plugin information for this
particular project build, it is intended to configure project builds
that inherit from this one
<build>
<finalName>ParentPOMProj</finalName>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.5.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
</plugins>
</pluginManagement>
</build>
As mentioned in the docs, the child project also needs to reference the plugin:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<!-- inherits config from parent: can override if required -->
</plugin>
</plugins>
</build>
After researching further, I understood that the java version in maven-compiler-plugin in parent pom applies to the child POMs but not to the parent itself. Basically, most of the time, it is not recommend to keep any source code in parent project, it is barely to handle all the build configuration for the child modules. Here are the updated POMS :

You should check the compliance of the project. Right click on the project in the Project Explorer of Eclipse, then go to Properties, and set it as shown on the picture (you can also set it to version 1.7 if the proper JDK is installed):
I have the next project structure:
app
module1
module2
...
moduleN
parent-pom
Project app contains only properties files and JasperReports's reports templates. Pom.xml of app:
<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">

<packaging>pom</packaging>
<modules>
<module>../module1</module>
<module>../module2</module>
...
<module>../moduleN</module>
</modules>
I want to add jasperreports-maven-plugin for project app. I've tried next code (before <modules> section), but it doesn't work (self build wasn't called):
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jasperreports-maven-plugin</artifactId>
<configuration>
<sourceDirectory>${basedir}/config/templates</sourceDirectory>
<outputDirectory>${basedir}/config/templates</outputDirectory>
</configuration>
<executions>
<execution>
<goals>
<goal>compile-reports</goal>
</goals>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>net.sf.jasperreports</groupId>
<artifactId>jasperreports</artifactId>
<version>${jasperreports.version}</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
Is it possible to add self build to pom with modules?
The app project packaging is set to pom - so it can't have any other artifacts. You will need to move the jasper reports to one of the other modules or a separate module.
