1. 找出所有被用于一個以上模塊的依賴，然后將其向上移到父POM的dependencyManagement片段 <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> <version>2.0.7</version> </dependency> <dependency> <groupId>org.apache.velocity</groupId> <artifactId>velocity</artifactId> <version>1.5</version> </dependency> </dependencyManagement> 2. 在這些依賴配置被上移之后，我們需要為每個POM移除這些依賴的版本，否則它們會覆 蓋定義在父項(xiàng)目中的dependencyManagement。 <dependencies> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-annotations</artifactId> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate</artifactId> </dependency> </dependencies> 3. 修復(fù)兄弟依賴不匹配問題 <properties> <hibernate.annotations.version>3.3.0.ga</hibernate.annotations.version> </properties> <dependencyManagement> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-annotations</artifactId> <version>${hibernate.annotations.version}</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-commons-annotations</artifactId> <version>${hibernate.annotations.version}</version> </dependency> </dependencyManagement> 4. 優(yōu)化插件，解決插件重復(fù) <pluginManagement> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.5</source> <target>1.5</target> </configuration> </plugin> </plugins> </pluginManagement> 如此標(biāo)注后，繼承者都能使用此插件。 |
