Maven中的两种依赖关系版本 [英] two versions of dependencies in maven

问题描述

有没有一种方法可以传递命令开关来更改我的依赖关系?

is there a way where i can pass a command switch to change my dependencies?

意思是，我有

<dependency>
            <groupId>api</groupId>
            <artifactId>api</artifactId>
            <version>0.0.1-SNAPSHOT</version>

        </dependency>

        <dependency>
            <groupId>org.apache.struts</groupId>
            <artifactId>struts2-core</artifactId>

        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>

        </dependency>

并将其设置为如果我这样做

and set it up in such a way where if i do

mvn软件包-已提供

mvn package -Dprovided

我的有效POM为

<dependency>
            <groupId>nmsc</groupId>
            <artifactId>nmsc_api</artifactId>
            <version>0.0.1-SNAPSHOT</version>

        </dependency>

        <dependency>
            <groupId>org.apache.struts</groupId>
            <artifactId>struts2-core</artifactId>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <scope>provided</scope>
        </dependency>

在不使用配置文件作为配置文件的情况下，我需要将依赖项放入两次.这可能吗?

without using profiles as profiles require me to put the dependencies in twice. is this possible?

推荐答案

如果将配置文件与变量配对，则使用配置文件不需要您多次列出依赖项，尽管如果只是针对单个属性执行此操作，那么也许您应该直接覆盖属性:

Using profiles doesn't require you to list the dependencies multiple times if you pair it with variables, though if you're just doing that for a single property, then maybe you should just override a property directly:

<properties>
    <myExeScope>compile<myExeScope>
</properties>

<dependencies>
    <dependency>
        <groupId>nmsc</groupId>
        <artifactId>nmsc_api</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>org.apache.struts</groupId>
        <artifactId>struts2-core</artifactId>
        <scope>${myExeScope}</scope>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <scope>${myExeScope}</scope>
    </dependency>
</dependencies>

然后，您应该能够覆盖指定依赖项的范围:

Then you should be able to override the scope of the specified dependencies:

mvn -DmyExeScope=provided

请注意，我尚未对此进行编译，因此，如果有错别字，请更正它们并记录下更正.
