请帮帮我,我是Maven的新手.我试图在Maven项目文件夹的不同目录中生成目标文件夹.根据我的要求,当我构建我的maven项目时,生成的war文件应放在另一个文件夹中,如C:\naresh文件夹.

这是我的代码:

<project xmlns="http://maven.apache.org/POM/4.0.0"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
   http://maven.apache.org/xsd/maven-4.0.0.xsd">
   <packaging>war</packaging>
   <modelVersion>4.0.0</modelVersion>
   <groupId>com.test</groupId>
   <artifactId>project</artifactId>
   <version>1.0</version>

   <build>
    <directory>${project.basedir}/target</directory>
     <outputDirectory>C:\Software\${project.basedir}/target</outputDirectory>

    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
             <configuration>
               <warSourceDirectory>WebContent</warSourceDirectory>
             </configuration>
        </plugin>
    </plugins>

    </build>
</project>

我正在研究Jasper报告.我尝试生成excel文件,但我得到的代码如下.

JasperReport jasperReport = JasperCompileManager.compileReport("C:\\jasper files\\report1.jrxml"); 
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, new HashMap(), new JREmptyDataSource());

JRXlsExporter exporterXLS = new JRXlsExporter(); 
exporterXLS.setParameter(JRXlsExporterParameter.JASPER_PRINT, jasperPrint); 
exporterXLS.setParameter(JRXlsExporterParameter.OUTPUT_STREAM, "sample1.xls"); 
exporterXLS.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET, Boolean.TRUE); 
exporterXLS.setParameter(JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND, Boolean.FALSE); 
exporterXLS.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE); 
exporterXLS.exportReport();
