导出和运行 Intellij .jar 项目

Question

我按照this 问题中的步骤使用 Intellij 导出了一个 Java 项目，并在%PROJECT_ROOT%/out/artifacts/ContactRetriever.jar 中获得了一个 .jar 文件。 但是，当从命令行运行 .jar 文件时，

java -jar ContactRetriever.jar

给出以下输出：

    Xalan-J command line Process class options:

                            -Common Options-

       [-XSLTC (use XSLTC for transformation)]
       [-IN inputXMLURL]
       [-XSL XSLTransformationURL]
       [-OUT outputFileName]
       [-E (Do not expand entity refs)]
       [-EDUMP {optional filename} (Do stackdump on error.)]
       [-XML (Use XML formatter and add XML header.)]
       [-TEXT (Use simple Text formatter.)]
       [-HTML (Use HTML formatter.)]
       [-PARAM name expression (Set a stylesheet parameter)]
       [-MEDIA mediaType (use media attribute to find stylesheet associated with a d
    ocument.)]
       [-FLAVOR flavorName (Explicitly use s2s=SAX or d2d=DOM to do transform.)]
       [-DIAG (Print overall milliseconds transform took.)]
       [-URIRESOLVER full class name (URIResolver to be used to resolve URIs)]
       [-ENTITYRESOLVER full class name (EntityResolver to be used to resolve entiti
    es)]

我的项目的清单文件 (MANIFEST.MF) 包含：

Manifest-Version: 1.0
Main-Class: Main

Main 是主类（入口点）。

项目的布局是：

项目结构工件是：

和模块：

为什么 main 没有被执行？

编辑：

main中的代码是：

    }
}

就像错误所说的那样，您有一个重复的依赖项： org.seleniumhq.selenium/selenium-java 删除其中一个依赖项，您的应用程序必须运行良好。

然后添加maven的配置来创建manifest文件：

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
            <configuration>
                <source>${java.specification.version}</source>
                <target>${java.specification.version}</target>
            </configuration>
        </plugin>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>2.5</version>
            <configuration>
                <archive>
                    <manifest>
                        <mainClass>Main</mainClass>
                        <addClasspath>true</addClasspath>
                        <classpathPrefix>lib/</classpathPrefix>
                    </manifest>
                </archive>
            </configuration>
        </plugin>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <version>2.9</version>
            <executions>
                <execution>
                    <id>copy-dependencies</id>
                    <phase>package</phase>
                    <goals>
                        <goal>copy-dependencies</goal>
                    </goals>
                    <configuration>
                        <outputDirectory>${project.build.directory}/lib/</outputDirectory>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

我也遇到过这个问题，发现Intellij会在src/main/java下自动生成META-INF/MANIFEST.IF，但应该是在src/main/java/resources下，移动到正确的目录即可。它对我有用。
