創建 maven 插件

創建 maven 插件：

刪除所有資源文件夾 mac 目錄下面所有 grf 文件（target/classes/mac/**/*.grf）裏面的內容：

<Property fileURL="src/main/resources/workspace.prm" id="GraphParameter0"/>
<Property fileURL="src/main/resources/workspace.prm" id="GraphParameter1"/>
<Property fileURL="src/main/resources/workspace.prm" id="GraphParameter2"/>

}

3) 安裝插件
mvn -Dmaven.test.skip=true install

4) 使用，在工程 pom.xml 加入如下內容：
將 < > " 用轉義字符替換掉。

	<build>
		<resources>
			<resource>
				<directory>${basedir}</directory>
				<includes>
					<include>mac/**/*.*</include>
				</includes>
			</resource>

			<resource>
                <directory>src/main/resources</directory>                
			</resource>
		</resources>

        <plugins>
              <plugin>
                <groupId>org.xmlasia.plugins</groupId>
                <artifactId>edit-resource-maven-plugin</artifactId>
                <version>1.0-SNAPSHOT</version>

                <configuration>
                    <file>target/classes/mac/**/*.grf</file>
                    <commentStrs>
                        <param><Property fileURL="src/main/resources/workspace.prm" id="GraphParameter0"/></param>
                        <param><Property fileURL="src/main/resources/workspace.prm" id="GraphParameter1"/></param>
                    </commentStrs>
                </configuration>

                <executions>
                  <execution>
                    <phase>compile</phase>
                    <goals>
                      <goal>editResource</goal>
                    </goals>
                  </execution>
                </executions>
              </plugin>            
        </plugins>

5) 打包工程 mvn -Dmaven.test.skip=true package
