Maven and adding JARs to system scope

by

I don’t know the real reason but Maven pushes developers to install all libraries (custom too) into some maven repositories, so scope:system is not well liked, A simple workaround is to use maven-install-plugin

follow the usage:

write your dependency in this way

<dependency>
    <groupId>com.mylib</groupId>
    <artifactId>mylib-core</artifactId>
    <version>0.0.1</version>
</dependency>

then, add maven-install-plugin

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-install-plugin</artifactId>
    <version>2.5.2</version>
    <executions>
        <execution>
            <id>install-external</id>
            <phase>clean</phase>
            <configuration>
                <file>${basedir}/lib/mylib-core-0.0.1.jar</file>
                <repositoryLayout>default</repositoryLayout>
                <groupId>com.mylib</groupId>
                <artifactId>mylib-core</artifactId>
                <version>0.0.1</version>
                <packaging>jar</packaging>
                <generatePom>true</generatePom>
            </configuration>
            <goals>
                <goal>install-file</goal>
            </goals>
        </execution>
    </executions>
</plugin>

pay attention to phase:clean, to install your custom library into your repository, you have to run mvn clean and then mvn install
