pom.xml操作文件

       maven和ant的完美结合案例。

       1、加载 ant-contrib包

 <profiles>
        <profile>
            <id>production</id>
            <build>
                <plugins>
                    <plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-antrun-plugin</artifactId>
                        <version>${maven-antrun-plugin.version}</version>
                        <executions>
                            <execution>
                                <id>maven-ant</id>
                                <phase>compile</phase>
                                <goals>
                                    <goal>run</goal>
                                </goals>
                                <configuration>
                                    <tasks>
                                        <echo>settings.localRepository : ${settings.localRepository}</echo>
                                        <echo>project.build.outputDirectory : ${project.build.outputDirectory}</echo>
                                        <taskdef resource="net/sf/antcontrib/antlib.xml">
                                            <classpath>
                                                <pathelement
                                                    location="${settings.localRepository}/ant-contrib/ant-contrib/${ant-contrib.version}/ant-contrib-${ant-contrib.version}.jar" />
                                            </classpath>
                                        </taskdef>

                                    </tasks>
                                </configuration>
                            </execution>
                        </executions>
                    </plugin>
                </plugins>
            </build>
        </profile>
    </profiles>

       2、生产的log4j替代测试环境的log4j，并把配置文件移动到WEB-INF/classes。

Maven内置变量说明：

${basedir} 项目根目录

${project.build.directory} 构建目录，缺省为target

${project.build.outputDirectory} 构建过程输出目录，缺省为target/classes

${project.build.finalName} 产出物名称，缺省为${project.artifactId}-${project.version}

${project.packaging} 打包类型，缺省为jar

${project.xxx} 当前pom文件的任意节点的内容

        <profile>
            <id>production</id>
            <build>
                <plugins>
                    <plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-antrun-plugin</artifactId>
                        <version>${maven-antrun-plugin.version}</version>
                        <executions>
                            <execution>
                                <phase>compile</phase>
                                <goals>
                                    <goal>run</goal>
                                </goals>
                                <configuration>
                                    <tasks>
                                        <echo>Before log4j.properties move</echo>
                                        <move file="${project.build.outputDirectory}/log4j.production.properties" tofile="${project.build.outputDirectory}/log4j.properties" />
                                        <echo>After log4j.properties move</echo>

                                        <echo>Begin conf move</echo>
                                        <copy todir="${project.build.outputDirectory}">
                                            <fileset dir="${reb.target.dir}" />
                                        </copy>
                                        <echo>After conf move</echo>
                                    </tasks>
                                </configuration>
                            </execution>
                        </executions>
                    </plugin>
                </plugins>
            </build>
        </profile>
    </profiles>
