如何将scala源附加到我的Maven jar? [英] How do I attach scala sources to my maven jar?

问题描述

我有一个包含Java和Scala混合代码的项目，该项目使用maven进行依赖和构建管理.我使用maven-source-plugin构建了一个可以上传到我的Maven镜像的sources-jar，它对于 java 源(在src/main/java中)工作得很好，但是对于 scala 源(在src/main/scala中).

I have a project with mixed java and scala code, that uses maven for dependency and build management. I use the maven-source-plugin to build a sources-jar that gets uploaded to my maven mirror, which works well for the java sources (in src/main/java), but not for the scala sources (in src/main/scala).

在scala-maven-plugin 网页上找不到任何帮助，但我可能错过了一些东西.无法在罐子中附加scala源吗?

I didn't find any help on the scala-maven-plugin webpage, but I may have missed out on something. Is it not possible to attach scala sources in the jar?

我应该注意，类文件都在那里，因此取决于库的工作情况，只是缺少了scala源.

I should note that the class files are all there, so depending on the library works fine, it's just that the scala sources are missing.

推荐答案

我遇到了类似的问题；我加了maven-source-plugin的罚款，但看到了

I had a similar problem; I'd added the maven-source-plugin fine, but was seeing

[INFO] --- maven-source-plugin:3.0.0:jar (attach-sources) @ foo-bar ---
[INFO] No sources in project. Archive not created.

当我编译我的Scala项目时.

when I compiled my Scala project.

要解决此问题，我在scala-maven-plugin配置中添加了add-source目标，例如:

To fix this, I added the add-source goal to my scala-maven-plugin config, eg:

<plugin>
    <groupId>net.alchim31.maven</groupId>
    <artifactId>scala-maven-plugin</artifactId>
    <version>3.2.0</version>
    <executions>
        <execution>
            <id>scala-compile-first</id>
            <phase>process-resources</phase>
            <goals>
                <goal>compile</goal>
                <goal>add-source</goal>
            </goals>
        </execution>
        ...
    </executions>
    ...
</plugin>

这会将您的Scala源代码添加到pom中，从而使maven-source-plugin查找源文件并将其放入源jar中.

This adds your Scala source to the pom, which in turn allows the maven-source-plugin to find the source files and put them in a source jar.
