‘build.plugins.plugin.version’ for com.pyx4me:proguard-maven-plugin is missing. @ line 42, column 12
执行Maven Install的时候提示如下警告信息：
[WARNING] [WARNING] Some problems were encountered while building the effective model for xunge-middleware:xunge-middleware:war:0.0.1-SNAPSHOT[WARNING] ‘build.plugins.plugin.version’ for com.pyx4me:proguard-maven-plugin is missing. @ line 42, column 12[WARNING] [WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.[WARNING] [WARNING] For this reason, future Maven versions might no longer support building such malformed projects.[WARNING]
其实警告信息忽略不管也可以的，不过这里的警告是关于插件版本的，最好还是指定版本：
>proguard-maven-plugin</artifactId>**<version>2.0.4</version>**>package>proguard>>true>>lib/servlet-api.jar>false>>net.sf.proguard>4.8></dependencies></plugin>
添加了<version>2.0.4</version>警告就消失了。
，大海，别为森林的渺小而沮丧，
