如 cmets 中所述,System 范围已弃用。最好的方法是使用像 jFrog artifactory 这样的工件管理器,或者在本地存储库 {home-dir}\.m2 中安装您喜欢的依赖项。
为此,您可以使用Maven install command:
mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging>
假设我们有一个位于项目根目录src\lib\my.jar 中的my.jar 文件
然后将其作为常规dependency 添加到我的项目的dependencies:
<dependency>
<groupId>a.b</groupId>
<artifactId>my</artifactId>
<version>9.0.0</version>
</dependency>
但是,如果您想要一种自动方式将位于 src/lib 中的 jar 安装到本地存储库中,可以使用 Maven install plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<executions>
<execution>
<id>install-external-non-maven-jar</id>
<phase>clean</phase>
<configuration>
<repositoryLayout>default</repositoryLayout>
<groupId>a.b</groupId>
<artifactId>my</artifactId>
<version>9.0.0</version>
<file>${basedir}/src/lib/my.jar</file>
<packaging>jar</packaging>
<generatePom>true</generatePom>
</configuration>
<goals>
<goal>install-file</goal>
</goals>
</execution>
</executions>
</plugin>
通过执行mvn clean 命令,my.jar 文件将被安装到本地仓库,然后通过mvn package 或mvn install 命令执行,您的war 文件将被创建。
