添加 java 源代码(.java 文件)以在 Maven 中测试 jar [英] Adding java source (.java files) to test jar in Maven

问题描述

我正在使用我的 pom.xml 并且能够为 src/main/java(比如 app.jar)以及 src/test/java(比如 app-test.jar)生成 jar.我还能够将我的 java 源代码作为 app.jar 的一部分包含在内(即在 jar 中有我的 .class 和我的 .java 文件).

I'm making use of my pom.xml and am was able to generate the jar for src/main/java (say app.jar) as well as for src/test/java (say app-test.jar). I was also able to include my java sources as part of the app.jar (i.e. have both my .class as well as my .java files in the jar).

但是对于我的 app-test.jar，我无法在其中包含我的 .java 文件.

However for my app-test.jar, i'm not able to include my .java files in it.

这是我的 pom.xml:

This is my pom.xml:

任何帮助将不胜感激.

关于 Whaley 建议的帖子更新:

尝试了 maven-antrun-plugin，但是在运行 mvn 包 之后，我现在在我的 tests.jar 中得到的只是 META-INF 文件夹..java 和 .class 未包含在内:

Tried the maven-antrun-plugin, but rt now after running mvn package all i'm getting inside my tests.jar is the META-INF folder. .java and .class are not getting included:

这是 pom.xml 的一部分

This is the part of the pom.xml

    <resources>
      <resource>

                 </copy>

推荐答案

我认为您可能需要使用程序集插件生成自定义程序集:

I think you probably need to generate a custom assembly using the assembly plugin:

http://maven.apache.org/plugins/maven-assembly-plugin/single-mojo.html

但更简洁的解决方案是使用源插件单独打包测试源

But a much cleaner solution would be to package test sources separately using the source plugin

http://maven.apache.org/plugins/maven-source-plugin/test-jar-mojo.html

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-source-plugin</artifactId>
    <version>2.1.2</version>
    <executions>
      <execution>
        <id>attach-test-sources</id>
        <goals>
          <goal>test-jar-no-fork</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

然后，您可以在类路径上同时拥有测试源 jar 和测试类 jar，并执行以下操作:

you can then have both the test source jar and the test class jar on your classpath and do something like this:

YourClassName.class.getResource("YourClassName.java");

或更笼统地说:

public static InputStream getSourceForClass(final Class<?> clazz) {
    final String baseName = clazz.getSimpleName();
    return clazz.getResourceAsStream(baseName + ".java");
}
