在Intellij IDE中的maven项目中添加外部jar作为依赖项

Question

我正在使用Intellij社区版v2020.3.2和Java8。

我通过以下步骤添加外部jar文件，file-

执行在IDE中运行良好。但是当使用maven安装时会抛出错误“包包名不存在”。

我的pom。xml看起来像

当我移除外部jar时，maven安装工作正常。

Answer 1

下面是我如何将罐子添加到maven POM中的：

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-install-plugin</artifactId>
            <version>2.5.2</version>
            <executions>
                <execution>
                    <id>FIRST_LIBRARY_ID</id>
                    <phase>initialize</phase>
                    <goals>
                        <goal>install-file</goal>
                    </goals>
                    <configuration>
                        <file>lib/my_lib_1.jar</file>
                        <groupId>com.group</groupId>
                        <artifactId>FIRST_LIBRARY_ID</artifactId>
                        <version>1.0</version>
                        <packaging>jar</packaging>
                    </configuration>
                </execution>
                <execution>
                    <id>SECOND_LIBRARY_ID</id>
                    <phase>initialize</phase>
                    <goals>
                        <goal>install-file</goal>
                    </goals>
                    <configuration>
                        <file>lib/my_lib_2.jar</file>
                        <groupId>com.group</groupId>
                        <artifactId>SECOND_LIBRARY_ID</artifactId>
                        <version>1.0</version>
                        <packaging>jar</packaging>
                    </configuration>
                </execution>
            </executions>
        </plugin>

然后只需将它们添加到依赖项：

    <dependency>
        <groupId>com.group</groupId>
        <artifactId>FIRST_LIBRARY_ID</artifactId>
        <version>1.0</version>
    </dependency>
    <dependency>
        <groupId>com.group</groupId>
        <artifactId>SECOND_LIBRARY_ID</artifactId>
        <version>1.0</version>
    </dependency>

你可以把你想要的放在里

Answer 2

要在Maven中使用本地jar，首先需要将这个jar安装到Maven本地存储库中。然后可以在Maven pom中将其指定为依赖项。xml构建文件和IDE也将根据Maven配置自动链接它。您可以使用类似的命令导入它：

mvn install:install-file \
   -Dfile=<path-to-file> \
   -DgroupId=<group-id> \
   -DartifactId=<artifact-id> \
   -Dversion=<version> \
   -Dpackaging=<packaging> \
   -DgeneratePom=true

请参见以下答案：

警告：请勿在基于Maven/Gradle的项目中手动修改IDE项目结构设置，因为在Maven/Gradle重新加载后，IDE将重置此手动配置。
