如何使用 maven 将 Java 项目的 python 文件包含到 .war 中？

Question

I have Java project made with maven. So I have typical maven project layout. And I use Jython. So I got few python files. Wich I use through PythonInterpreter in Java classes.
I place my python files in src/main/py folder. And I use this path to import the modules by interpreter. It works fine on my laptop.

The problem is:
When I do mvn install, this folder does not goes to the war.
I read about maven resources plugin and added this folder as a resource. Like this:

<resources>
    <resource>
        <directory>src/main/py</directory>
    </resource>
    <resource>
        <directory>src/main/resources</directory>
    </resource>
</resources>

I that case it adds everything that folder contents, to web-inf/ directly, but not in the src/main/py. So that path is invalid for application in war archive.

Question is:
How should I place this python resource and what I should write in pom.xml, to be able to use the same path on the laptop, and the server?

Answer 1

Can you try including targetPath in the resource element as below:

<resource>
            <targetPath>../</targetPath>
            <directory>src/main/py</directory>
            <includes>
                <include>**/*.py</include>
            </includes>

</resource>

Answer 2

我建议使用 src/main/scripts 文件夹并检查它们是否打包到 war 中，如果这不起作用，请检查maven-war-plugin的文档，并按照文档中的描述使用 war 插件定义它。

Answer 3

<resources>
    <resource>
        <directory>src/main/py</directory>
    </resource>
    <resource>
        <directory>src/main/resources</directory>
    </resource>
</resources>

is actually enough to include into jar/war file.

It is not recommended to use src/main/py in your python script, think as src/main/py as working/current folder for you python
