Maven Copy Folder Before War File Generation

Question

I have two Git repositories. One repositary is java services (maven web project) and another repository consists of UI {HTML, JS, CSS}(non maven), At the time of java services repository build I want to include the latest UI (master) into the war file. I tried with maven-resources-plugin

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.2</version>
                <configuration>
                    <source>1.7</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
            <plugin>
                <artifactId>maven-resources-plugin</artifactId>
                <version>2.7</version>
                <executions>
                    <execution>
                        <id>copy-resources</id>
                        <!-- here the phase you need -->
                        <phase>install</phase>
                        <goals>
                            <goal>copy-resources</goal>
                        </goals>
                        <configuration>
                            <outputDirectory>${basedir}/target/</outputDirectory>
                            <resources>
                                <resource>
                                    <directory>/home/srinivas/AAA/bb/</directory>
                                </resource>
                            </resources>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

mvn install

It copies the resources to target folder but it is not placing them in the war file

Answer 1

You are using the wrong phase in your execution as the package phase is actually the phase where your war is created, so you need to execute at an earlier phase e.g. prepare-package.

You should definitely read Introduction to the Build Lifecycle for clarification.

In addition you should not become accustomed to pulling in resources via maven-resources-plugin from the file system. This is generally frowned upon as bad practice since other developers will not be able to reproduce your build.

Using a repository manager to store your dependencies is the way to go here. Read Why do I need a Repository Manager? to get started.
