maven随笔

1、原来jetty-maven-plugin是eclipse的。maven-jetty-plugin是codehaus的。

2、打包war时排除不需要的jar：

<project>  ...  <dependencies>    <dependency>      <groupId>org.foo</groupId>      <artifactId>bar-jar1</artifactId>      <version>${pom.version}</version>      <optional>true</optional>      <!-- goes in manifest classpath, but not included in WEB-INF/lib -->    </dependency>    <dependency>      <groupId>org.foo</groupId>      <artifactId>bar-jar2</artifactId>      <version>${pom.version}</version>      <!-- goes in manifest classpath, AND included in WEB-INF/lib -->    </dependency>    <dependency>      <groupId>org.foo</groupId>      <artifactId>bar-jar3</artifactId>      <version>${pom.version}</version>      <scope>provided</scope>      <!-- excluded from manifest classpath, and excluded from WEB-INF/lib -->    </dependency>    ...  </dependencies>  ...</project>
