Question

有一个Maven项目曾经有过JAR包装类型。现在该项目已经发展，并且需要将其构建为EAR，包括JAR本身及其依赖项。

这是否必然意味着我必须引入第二个带有EAR包装类型的POM？是否可以从单个Maven项目构建JAR + EAR？这背后的原因是我真的不想从根本上重新组织我的存储库结构。

如果不可能，我想我需要以某种方式重新组织项目结构以使用Maven模块。在这种情况下，您会推荐什么（子）模块结构？

Answer 1

你需要3个pom，这是一个有效的例子;

pom 1是父

<?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>com.greg</groupId>
  <artifactId>ear-example</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>pom</packaging>

  <name>ear-example</name>
  <modules>
    <module>example-jar</module>
    <module>example-ear</module>
  </modules>

</project>

pom 2是罐子或战争

<?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"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>

  <parent>
    <groupId>com.greg</groupId>
    <artifactId>ear-example</artifactId>
    <version>1.0-SNAPSHOT</version>
  </parent>

  <artifactId>example-jar</artifactId>
  <packaging>jar</packaging>

  <name>com.greg</name>
  <url>http://maven.apache.org</url>
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
</project>

pom 3是依赖于jar / war

的耳朵

<?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"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>

  <parent>
    <groupId>com.greg</groupId>
    <artifactId>ear-example</artifactId>
    <version>1.0-SNAPSHOT</version>
  </parent>

  <artifactId>example-ear</artifactId>
  <packaging>ear</packaging>

  <dependencies>
    <dependency>
      <groupId>com.greg</groupId>
      <artifactId>example-jar</artifactId>
      <version>${project.version}</version>
    </dependency>
  </dependencies>

  <build>
   <plugins>
     <plugin>
        <artifactId>maven-ear-plugin</artifactId>
        <version>2.10.1</version>
        <configuration>
        </configuration>
      </plugin>
    </plugins>
  </build>

</project>

Answer 2

我认为你可以使用maven war插件在每次构建项目时生成一个war文件

 <build>
<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-ear-plugin</artifactId>
    <version>2.3.2</version>
    <!-- configuring the ear plugin -->
    <configuration>
      <modules>
        <!-- all your modles -->
      </modules>
    </configuration>
  </plugin>
</plugins>

从单个Maven项目构建EAR
