Tycho 中使用target platform做为编译设置

在使用Tycho编译Eclips plugin项目时，需要制定Eclipse IDE的相关依赖配置，通常使用的都是配置一个repository在pom.xml中，如下：

 <properties>
  <eclipse-repo.url>http://download.eclipse.org/releases/latest</eclipse-repo.url>
 </properties>
 
 <repositories>
  <repository>
   <id>eclipse-release</id>
   <url>${eclipse-repo.url}</url>
   <layout>p2</layout>
  </repository>
 </repositories>

下面为大家介绍另一种使用target platform作为编译配置的设置方法。

1. 创建target platform文件

参考https://blog.csdn.net/devin_xin/article/details/104898574
这里需要注意的是：target 文件的名字一定要和其所在的项目的artifact id相同且以.target结尾。

2.为target文件所在的项目创建pom.xml文件

<project>
    <modelVersion>4.0.0</modelVersion>
    
    <groupId>com.devinxin.example.tycho</groupId>
    <artifactId>target-platform</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>eclipse-target-definition</packaging>
</project>

3.更显aggregator pom和configuration相关内容

<project>
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.devinxin.example.tycho</groupId>
    <artifactId>com.devinxin.example.parent</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>pom</packaging>
    <modules>
        ...
        <module>target-platform</module>
    </modules>
  ...
  <!-- 注释掉以前的方式
  <properties>
  <eclipse-repo.url>http://download.eclipse.org/releases/latest</eclipse-repo.url>
 </properties>
 
 <repositories>
  <repository>
   <id>eclipse-release</id>
   <url>${eclipse-repo.url}</url>
   <layout>p2</layout>
  </repository>
 </repositories>
</project>
-->
