java - 当我尝试在 pom.xml 中指定 list 时出现格式错误的 POM

Question

这个问题已经有答案了:

Maven not recognising 'configuration' tag in pom.xml (1 个回答)

已关闭 4 年前。

我将我的应用程序打包为

mvn package

它创建了一个jar文件名为 JasperCSVDataSource-1.0-SNAPSHOT.jar

当我尝试运行 jar 文件时:

java -jar JasperCSVDataSource-1.0-SNAPSHOT.jar

我收到一条错误消息 no main manifest attribute, in target/JasperCSVDataSource-1.0-SNAPSHOT.jar 。在创建的 JAR 中自动添加 list 文件，我更新了我的pom.xml添加以下内容:

<configuration>
  <archive>
    <manifest>
    <mainClass>com.comp.main.CommandLineRunner</mainClass>
    </manifest>
  </archive>
</configuration>

完整pom.xml看起来如下:

<?xml version="1.0" encoding="UTF-8"?>
<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">

    <modelVersion>4.0.0</modelVersion>
    <groupId>com.comp</groupId>

    <version>1.0-SNAPSHOT</version>

    <configuration>
    <archive>
        <manifest>
        <mainClass>com.suhail.main.CommandLineRunner</mainClass>
        </manifest>
    </archive>
    </configuration>

    <packaging>jar</packaging>

    <properties>

        <maven.compiler.target>1.8</maven.compiler.target>
    </properties>

    <dependencies>

        <dependency>
            <groupId>net.sf.jasperreports</groupId>
            <artifactId>jasperreports</artifactId>
            <version>6.8.0</version>
        </dependency>

        <dependency>

            <version>5.0.11</version>
        </dependency>
    </dependencies>    

</project>

但是现在当我尝试构建文件时，我收到一条错误消息:

我无法理解其中的原因。这不是将 list 文件添加到 jar 的正确方法吗？

您需要提供<configuration>带有特定 Maven 插件的标签。在这种情况下，它可能是 maven-jar-plugin所以你的pom.xml你的 <project> 里面应该有类似的东西标签

<build>
<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    ...
    <configuration>
      <archive>
        <manifest>
          <mainClass>com.comp.main.CommandLineRunner</mainClass>
        </manifest>
      </archive>
    </configuration>
    ...
  </plugin>
</plugins>
</build>
