eclipse maven .jar中沒有主清單屬性

報錯環境: windows系統eclipse maven 打包jar包后, 運行 java -jar 報錯

E:\My_java\mysql\target>java -jar original-mysql-0.0.1-SNAPSHOT.jar
original-mysql-0.0.1-SNAPSHOT.jar中沒有主清單屬性

解決方法

一.項目目錄

 

二. 首先在POM.XML 文件加入你用來打包的jar包的依賴,這里用shade

<!-- https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-shade-plugin -->
<dependency>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>3.2.1</version>
</dependency>

三.在POM文件加入build項

<build>
  <plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>3.2.1</version>
        <executions>
            <execution>
                <phase>package</phase>
                <goals>
                        <goal>shade</goal>
                </goals>
                    <configuration>
                        <transformers>
                            <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                <mainClass>org.feilong.mysql.SelectTest</mainClass>
                            </transformer>
                        </transformers>
                    </configuration>
            </execution>
        </executions>
     </plugin>
  </plugins>
</build>

四. 完整POM.XML配置文件

<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">

<!-- 反寫的公司網址+項目名 -->

  <!-- 項目名 + 模塊名 -->

  <!-- 版本號   SNAPSHOT 快照; alpha 內部測試; beta 公測; release 穩定 ga 正式版本-->
