Question

我正在尝试制作我的java maven项目的.jar。该项目本身是一个helloworld项目，所以我不会发布实际的Java代码。项目名称是test 这是test / 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/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>serge</groupId>
  <artifactId>test</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>jar</packaging>

  <name>test</name>
  <url>http://maven.apache.org</url>

 <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <jdk.version>1.6</jdk.version>
    </properties>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>2.3.2</version>
        <configuration>
            <source>${jdk.version}</source>
            <target>${jdk.version}</target>
        </configuration>
      </plugin>
      <plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-jar-plugin</artifactId>
  <version>2.4</version>
  <configuration>
    <archive>
        <manifest>
            <mainClass>com.mkyong.core.App</mainClass>
        </manifest>
    </archive>
  </configuration>
 </plugin>
    </plugins>
    </build>
</project>

这是我在运行mvn -e package test时遇到的错误：

Answer 1

好的，我已经弄明白我的具体问题是什么，但我认为我以前的方法也应该有效。

我在项目文件夹之外运行命令（＆＃39; test＆＃39;在这种情况下）。一旦我在文件夹内导航并运行mvn包，它就会在目标文件夹中生成.jar。

以前我试图以这种方式将项目传递给package命令：

mvn package test

Maven不会打包java项目
