我创建了我的第一个库，试图在其他使用maven构建战争文件的项目中导入该库。
第一次尝试是将jar作为外部jar文件手动包含在构建路径中，但没有成功...
然后在一些google之后，我发现如何使用以下命令在maven本地存储库中添加该库：
mvn install:install-file -Dfile=/Users/.../myfile.v1.jar -DgroupId=com.mycompany.app -DartifactId=app -Dversion=0.0.1-SNAPSHOT -Dpackaging=jar
并按如下所示添加到pom.xml中
<dependency>
<groupId>com.mycompany.app</groupId>
<artifactId>app</artifactId>
<version>0.0.1-SNAPSHOT</version>
<scope>system</scope>
<systemPath>/Users/.../myfile.v1.jar</systemPath>
</dependency>
由于无法获得很好的成绩，我一直在搜索，发现需要添加以下插件
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<includeSystemScope>true</includeSystemScope>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<webResources>
<resource>
<directory>/Users/../</directory>
<targetPath>BOOT-INF/lib/</targetPath>
<!-- <targetPath>WEB_INF/lib/</targetPath> just for none spring-boot project -->
<includes>
<include>**/*.jar</include>
</includes>
</resource>
</webResources>
</configuration>
</plugin>
但是当我尝试运行项目时，我得到了：
java.lang.ClassNotFoundException: com.mycompany.app.myclass
如果我运行mvn clean package，我会得到：
Execution default of goal org.springframework.boot:spring-boot-maven-plugin:1.2.3.RELEASE:repackage failed: Unable to find main class
有什么帮助吗？
让我补充一点，在我的应用程序（我要导入的应用程序）中，没有任何主要方法，并且没有使用sprintboot。
编辑添加两个POM
我的com.mycompany.app中的pom.xml

答案 0 :(得分：1)
首先，您应该学习如何使用Maven：https://maven.apache.org/
但是要解决您的问题：
您已将依赖项安装在本地存储库中。因此，您pom.xml中的依赖项必须如下所示：
<dependency>
<groupId>com.mycompany.app</groupId>
<artifactId>app</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
插件很简单：
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
仅此而已。 Maven默认会包含您的依赖项。
