Maven無法識別pom.xml中的“ configuration”標記

Question

我試圖把它放在我的pom.xml-

<configuration>
  <archive>
    <manifest>
  <mainClass>com.limetray.helper.App</mainClass>
    </manifest>
  </archive>
</configuration>

但收到此錯誤-

Malformed POM /home/rakesh/Desktop/limetray/lt-utils/pom.xml: Unrecognised tag: 'configuration' (position: START_TAG seen ...<url>http://maven.apache.org</url>\n  <configuration>... @10:18)  @ /home/rakesh/Desktop/limetray/lt-utils/pom.xml, line 10, column 18 -> [Help 2]

我的pom.xml-

<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/maven-v4_0_0.xsd">

您發布的<configuration>代碼段屬於<plugin>標記內。 具體來說，它屬於Apache Maven Jar插件內部。 請參閱下面的示例，以了解您在做什么錯。

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>3.0.2</version>
            <configuration>
                <archive>
                    <manifest>
                        <mainClass>com.limetray.helper.App</mainClass>
                    </manifest>
                </archive>
            </configuration>
        </plugin>
    </plugins>
</build>
