The POM for <some_project> is missing, no dependency information available

Question

What I am doing?

I have created a maven project, where I bundle some external jars

project/pom.xml
       /bin
           /safebrowsing2_2.11-0.2.5.jar
           /scala-http-client_2.11-1.0.jar

The libraries safebrowsing2_2.11-0.2.5.jar and scala-http-client_2.11-1.0.jar are bundled because they are not available in Nexus and are custom jars needed for legacy purposes.

pom.xml uses following plugins to bundle them up in one jar

         <plugins>
            <plugin>
                <groupId>com.googlecode.addjars-maven-plugin</groupId>
                <artifactId>addjars-maven-plugin</artifactId>
                <version>1.0.5</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>add-jars</goal>
                        </goals>
                        <configuration>
                            <resources>
                                <resource>
                                    <directory>${basedir}/bin</directory>
                                </resource>
                            </resources>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-shade-plugin</artifactId>
                <version>2.2</version>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>shade</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>

Question

Yes, I know that they do not have pom.xml, but how do I let the build pass and generate artifact?

Answer 1

Use the install-file goal of Maven's Install Plugin:

... to install an externally created artifact into the local repository, along with its POM.

Use the deploy-file goal of Maven's Deploy Plugin to:

install the artifact in the remote repository.

... rather than placing the artifacts in your project's directory.
