Maven:如何在建造后将我的jar安装到本地仓库

Question

我想构建一个包并将其安装到我的本地仓库.我的pom文件是:

<?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>

但是当我运行"mvn package"命令时,我得到一个没有文件的错误:/Users/me/MyApp/target/MyApp-1.0.0.jar所以我评论安装插件,运行"mvn package",uncoment install plugin并运行"mvn包".我可以一步到位吗？没有这个评论 - 取消评论的事情？

Answer 1

目前尚不清楚为什么需要调用install-file目标,maven-install-plugin但问题在于阶段.你<phase>validate</phase>应该在什么时候配置它<phase>package</phase>.

看看构建生命周期简介:阶段validate是Maven执行的第一个阶段.这时,罐子没有建成,所以无法工作.

如果您确实希望在包阶段(运行时mvn package)安装工件,则应将阶段设置为package.

请注意mvn package,您应该mvn install在不需要配置的情况下调用而不是运行maven-install-plugin.使用此命令,工件将自动安装在本地仓库中.
