Maven: How to install my jar to local repo after building

Question

I want to build a package and install it to my local repo. My pom file is:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.me</groupId>
    <artifactId>MyApp</artifactId>
    <version>1.0.0</version>
    <packaging>jar</packaging>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.3.1.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.version>1.8</java.version>
    </properties>

    <!-- This block declare a dependencies for this project -->
    <dependencies>

        <!-- Spring Boot -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

    </dependencies>

    <build>

        <!-- This block declare a plugins -->
        <plugins>

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <version>2.6</version>
            </plugin>

<!-- Installing to local repo -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-install-plugin</artifactId>
                <version>2.5.2</version>
                <configuration>
                    <groupId>com.me</groupId>
                    <artifactId>MyApp</artifactId>
                    <version>1.0.0</version>
                    <packaging>jar</packaging>
                    <file>/Users/me/MyApp/target/MyApp-1.0.0.jar</file>
                    <generatePom>true</generatePom>
                </configuration>
                <executions>
                    <execution>
                        <id>install-jar-lib</id>
                        <goals>
                            <goal>install-file</goal>
                        </goals>
                        <phase>validate</phase>
                    </execution>
                </executions>
            </plugin>

        </plugins>
    </build>

</project>

But when I run "mvn package" comand I get a error that there is no file: /Users/me/MyApp/target/MyApp-1.0.0.jar So I comment install plugin, run "mvn package", uncoment install plugin and run "mvn package". Could I do this thing in one step? Without this comment-uncomment thing?

Answer 1

from what i know, mvn clean install, put the package in the local repo, without any need of any plugin

Answer 2

It's not clear why you need to invoke the install-file goal of maven-install-plugin but the problem lies in the phase. You configured it with <phase>validate</phase> when it should be <phase>package</phase> instead.

Take a look at the Introduction to the Build Lifecycle: phase validate is the first phase that is executed by Maven. At this time, the jar was not built so it can't work.

If you really want the artifact to be installed on the package phase (when running mvn package) then the phase should be set to package.

Note that instead of running mvn package, you should just call mvn install without the need of configuring the maven-install-plugin. The artifact will be automatically installed in your local repo with this command.
