Question

出于性能原因，我需要在WAR存档旁边创建一个新的EAR工件，而不使用多个模块projekt 。 EAR将包含WAR（在/web子目录中）和静态application.xml文件。

我需要以非静态方式生成的是Java类和 Maven描述符文件（META-INF/maven/${groupId}/${artifactId}/pom.xml和META-INF/maven/${groupId}/${artifactId}/pom.properties）。

使用类没什么大不了的，但是如何生成Maven描述符文件并将其附加到新的EAR？

这很有效，但是在EAR存档中不会生成Maven描述符文件。

最简单的方法是拥有一个多模块项目。

父母喜欢：

<?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>

  <properties>
        <myproject.version>1.0-SNAPSHOT</myproject.version>
  </properties>

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

</project>

你有一场战争和耳朵项目：

<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>

然后只需将您需要的任何文件添加到ear项目的src / main / application目录中，它们将显示在ear文件的顶层。

解决方案是在准备包阶段之前将war包阶段移动到另一个阶段，然后有一个包含maven描述符文件的完整WAR存档。这意味着，准备好EAR档案时，所有数据都已准备就绪。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <executions>
        <execution>
        <phase>process-classes</phase>
        <goals>
            <goal>war</goal>
        </goals>
        </execution>
    </executions>                    
</plugin>

存档解压缩并在准备包阶段中使用，如前所述：

<!-- unzip the war -->
<unzip src="${project.build.directory}/${project.build.finalName}.war" dest="${project.build.directory}/war-exploded" />                                

<!-- move the war content -->
<move todir="${compile.dir}/web">
    <fileset dir="${project.build.directory}/war-exploded" />
</move>

Maven - 使用Maven描述符文件附加工件
