[英]Multi module maven project not deploying executable Jar for dependent module
[英]How to build an executable jar from multi module maven project?
我是maven的初學者,不懂很多東西。 我可以構建簡單的可執行jar,但是如何將multimodule maven項目構建到可執行jar中對我來說是不可思議的。 所以,我有三個項目。 家長:
<?xml version="1.0" encoding="UTF-8"?>
<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">
<modelVersion>4.0.0</modelVersion>
<groupId>org.example</groupId>
<artifactId>Test</artifactId>
<packaging>pom</packaging>
<version>1.0-SNAPSHOT</version>
<modules>
<module>Main</module>
<module>Dep</module>
</modules>
</project>
還有兩個子項目:
<?xml version="1.0" encoding="UTF-8"?>
<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">
<parent>
<artifactId>Test</artifactId>
<groupId>org.example</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>Main</artifactId>
<dependencies>
<dependency>
<groupId>org.example</groupId>
<artifactId>Dep</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
</dependencies>
</project>
和:
<?xml version="1.0" encoding="UTF-8"?>
<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">
<parent>
<artifactId>Test</artifactId>
<groupId>org.example</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>Dep</artifactId>
</project>
主模塊有Main類和main方法(lol)
public class Main {
public static void main(String[] args) {
Hello hello = new Hello();
System.out.println(hello.sayHello());
}
}
類Hello在Dep模塊中定義。 我應該在我的poms中添加什么來構建Main模塊中Main類的可執行jar作為入口點?
你需要為artifactid Main改變你的pom。 您需要添加maven-assembly-plugin
在它的配置中,您可以選擇在清單中指定mainClass。 這應該是Main類的完全限定名稱。
<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">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.example</groupId>
<artifactId>Test</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
<artifactId>Main</artifactId>
<properties>
<!-- plugins -->
<maven.assembly.plugin.version>2.4</maven.assembly.plugin.version>
<!-- dependencies -->
<dep.version>1.0-SNAPSHOT</dep.version>
</properties>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>

</plugins>
<pluginManagement>

<version>${maven.assembly.plugin.version}</version>

</build>
<dependencies>
<dependency>
<groupId>org.example</groupId>
<artifactId>Dep</artifactId>
<version>${dep.version}</version>
</dependency>
</dependencies>
</project>
在父項目上開始構建之后,它應該在Main模塊的目標子文件夾中創建可執行jar。 (一個名為Main-1.0-SNAPSHOT-jar-with-dependencies.jar的jar就是我得到的)
