How to use Maven Plugin Tools Java Annotations in the Java Library
How to use the Java annotation of the Maven plug -in tool in the Java class library
Overview:
The Maven plug -in tool is a framework for developing Maven plug -in, which simplifies the configuration and use process of the plug -in.This article will introduce how to use Maven Plugin Tools's Java annotations in the Java library to create a custom Maven plug -in.
Configuration step:
Here are a detailed step to use Maven Plugin Tools Java in the Java library.
Step 1: Create Maven project
First, create a new Maven project and configure the basic project structure.
Step 2: Add Maven Plgin Tools dependence
In the pom.xml file of the project, add Maven Plugin Tools to dependence:
<dependencies>
<dependency>
<groupId>org.apache.maven.plugin-tools</groupId>
<artifactId>maven-plugin-annotations</artifactId>
<version>3.6.0</version>
<scope>provided</scope>
</dependency>
</dependencies>
This will enable you to use Maven Plugin Tools's Java annotation.
Step 3: Create a custom Maven plug -in
In your Java class library project, create a new class and use Maven Plugin Tools Java annotations to define a custom Maven plug -in.
import org.apache.maven.plugin.AbstractMojo;
import org.apache.maven.plugin.MojoExecutionException;
import org.apache.maven.plugins.annotations.Mojo;
import org.apache.maven.plugins.annotations.Parameter;
@Mojo(name = "hello")
public class HelloMojo extends AbstractMojo {
@Parameter(property = "message", defaultValue = "Hello, Maven Plugin!")
private String message;
public void execute() throws MojoExecutionException {
getLog().info(message);
}
}
In the above sample code, we created a custom Maven plug -in called Hellomojo.@Mojo annotation is used to define the name of the plug -in, here is "Hello".@Parameter annotations are used to define parameters of plug -ins. Here we define a string parameter called "MESSAGE".
Step 4: Compile and generate plug -in description files
In the root directory of the project, use the Maven command to compile the project and generate a plug -in description file:
shell
mvn clean package
This will generate a plug-in description file that is located in the target/generald-society/annotations directory.
Step 5: Use custom plug -in in other projects
In the pom.xml file you want to use the Maven project of a custom plug -in, add the following plug -in configuration:
<build>
<plugins>
<plugin>
<groupId>your.plugin.groupId</groupId>
<artifactId>your-plugin-artifactId</artifactId>
<version>your-plugin-version</version>
<executions>
<execution>
<phase>your-plugin-phase</phase>
<goals>
<goal>hello</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
Instead the actual values of your custom plugin in your custom plugin,After the configuration is performed, the plug -in will be executed when performing MAVEN construction in the corresponding construction phase.
Summarize:
By using Maven Plugin Tools Java annotations, we can easily create a custom Maven plug -in.Using the above steps, creating and using custom plug -in in the Java library can enable us to manage and execute tasks in the process of Maven more efficiently.
