java – 编译多模块maven项目而无需安装到本地存储库

我的多模块maven项目中有编译(和打包)问题.编译两个项目中的一个项目时出现问题,这两个项目是兄弟项目并包含在父项目中,另一个项目依赖于另一项目.为简单起见,我在这里草绘项目文件夹结构和pom.xml内容.

父母的pom.xml

child1的pom.xml

<?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>
    <parent>
        <groupId>com.example.project</groupId>
        <artifactId>parent</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <groupId>com.example.project</groupId>
    <artifactId>child1</artifactId>
    <version>1.0-SNAPSHOT</version>
    <name>child1</name>
    <dependencies>
        <dependency>
            <groupId>${project.groupId}</groupId>
            <artifactId>child2</artifactId>
            <version>${project.version}</version>
        </dependency>
    </dependencies>
</project>

child2的pom.xml

<?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>
    <parent>
        <groupId>com.example.project</groupId>
        <artifactId>parent</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <groupId>com.example.project</groupId>
    <artifactId>child2</artifactId>
    <version>1.0-SNAPSHOT</version>
    <name>child2</name>
    <dependencies>
    </dependencies>
</project>

如图所示,child2是child1的依赖项. child1和child2是并行开发的.因此,在child2中的任何源代码更改之后,应该编译和部署child1而不进行任何其他操作.但我无法成功编译child1.在child1上运行mvn compile命令后出现此错误消息：

[ERROR] Failed to execute goal on project child1: Could not resolve dependencies for project com.example.project:child1: jar:1.0-SNAPSHOT: Could not find artifact com.example.project:child2:jar:1.0-SNAPSHOT -> [Help 1]

正如我所见,maven尝试在本地存储库中搜索child2.如果我在父项目上运行mvn install命令,则两个项目都将添加到本地存储库.然后任何编译child1的尝试都是成功的.这似乎是一种解决方案,但不方便.我想要的是编译child1,同时编写child1和child2而无需安装到本地存储库.
