maven - 在构建期间跳过依赖项

Question

我想在构建期间跳过 demo-api（这是另一个模块）。设置可选的 true 不起作用。关于如何跳过它但不从 pom.xml 中删除依赖项的任何建议？

Failed to execute goal on project [36mdemo-web[m: [1;31mCould not resolve dependencies for project demo-web:demo-web:war:1.0-SNAPSHOT: Failed to collect dependencies at demo-api:demo-api:jar:1.0-SNAPSHOT[m: Failed to read artifact descriptor for demo-api:demo-api:jar:1.0-SNAPSHOT: Could not find artifact demo-spring-boot:demo-spring-boot:pom:1.0-SNAPSHOT

    <dependency>
        <artifactId>demo-api</artifactId>
        <groupId>demo-api</groupId>
    <version>1.0-SNAPSHOT</version>
    <optional>true</optional>
    </dependency>

您可以将该依赖项放在配置文件中：

<?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/maven-v4_0_0.xsd">

    <modelVersion>4.0.0</modelVersion>
    <groupId>org.foo</groupId>
    <artifactId>foo</artifactId>
    <version>1.0.0-SNAPSHOT</version>

    <organization>
        <name>Example Company</name>
        <url>http://www.example.com/</url>
    </organization>

    <name>foo</name>
    <profiles>
        <profile>
            <id>includeBadDependency</id>
            <dependencies>
                <dependency>
                    <artifactId>demo-api</artifactId>
                    <groupId>demo-api</groupId>
                    <version>1.0-SNAPSHOT</version>
                </dependency>
            </dependencies>
        </profile>
    </profiles>

<!--    Normal dependencies go here-->
    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>4.2.5.RELEASE</version>
            <scope>provided</scope>
        </dependency>
    </dependencies>

</project>

当你构建这个项目时：

$ mvn verify # this will succeed

$ mvn verify -PincludeBadDependency

也许这可以给你一两个提示。

<scope>runtime</scope>

我认为这可以解决问题
