我想使用Maven从我的libs项目文件夹中加载所有JAR [英] I want to load all JARs from my libs project folder with Maven

问题描述

我有一个使用Maven的Java项目.在我的项目中，我有一个名为libs的文件夹，其中包含无法从Internet/外部存储库加载的所有JAR.

I have a Java project using Maven. In my project I have a folder called libs that contains all the JARs that I can't load from internet/external repository.

我的问题是如何指定Maven在打包，构建等过程中包括那些JAR?

My issue is how to specify to Maven to include those JARs during packaging, building etc.?

Maven的新手，很抱歉，这是一个愚蠢的问题.

New to Maven, sorry if it is a stupid question.

我有一个自动工具，它将在我的Git上查找我的pom.xml来构建&在不同的环境中部署我的项目.因此，如建议在此处将无济于事，因为它只能在我的PC上运行.如果我在JAR文件夹中添加libs文件夹，则无论我在哪里，它都可以使用.

EDIT : I have an automatic tool that will look up at my pom.xml on my Git to build & deploy my project on different environments. So adding it in local Maven repo, as suggested here will not help since it will work only on my PC. If I add a libs folder with my JARs it will work wherever I am.

如果不清楚或误解，请在评论中问我.

Ask me in comments if it's not clear or if I'm mistaken.

推荐答案

与您的EDIT相反，将其添加到本地Maven存储库将提供帮助，它可以按以下方式自动执行:

Contrary to your EDIT adding to the local Maven repo will help and it can be automated as follows:

• 请参见 jtahlborn的答案对在单个pom.xml中多个安装:安装文件. (maven-install-plugin的当前版本是2.5.2.我会使用它而不是默认版本.)

• <configuration>的外观应为:

• See jtahlborn's answer to Multiple install:install-file in a single pom.xml. (The current version of the maven-install-plugin is 2.5.2. I'd use that rather than the default.)

• The <configuration>s should look like:

  <configuration>
    <file>${project.basedir}/path/to/your/libs/lib-X.jar</file>
    <repositoryLayout>default</repositoryLayout>

    <!-- match the dependency declaration for this artifact -->
    <groupId>logan.wlv</groupId>
    <artifactId>lib-X</artifactId>
    <version>x.y.z</version> 
    <packaging>jar</packaging>
    <!-- -------------------------------------------------- -->
  </configuration>

将install-plugin声明放入构建配置文件，例如lib.

Put the install-plugin declaration into a build profile, e.g. lib.

在每一个新PC上运行一次mvn initialize -P lib(并在libs的内容之后更改一次，因此更改了install-plugin声明)，然后再调用首先解决依赖关系的任何阶段，例如compile.

Run mvn initialize -P lib once on every new PC (and once after the contents of libs, and hence the install-plugin declaration, changed) before invoking any phase that resolves dependencies first, e.g. compile.

或

• 使用以下方法进一步自动化:

• Automate this even further with:

  <profile>
    <id>lib</id>
    <activation>
      <file>
        <missing>${settings.localRepository}/logan/wlv/lib-X/x.y.z/lib-X-x.y.z.jar</missing>
      </file>
    </activation>
    ...
  <profile>

这种功能仅在mvn initialize时即可运行，而无需第一次激活显式配置文件.

Such being able to run just mvn initialize without the explicit profile activation the very first time.
