Question

通常下面的pom配置对我有用。我过去成功地将我的jar文件源作为依赖项添加到我的项目中了吗？

我有两个像这样定义的jar文件：

<dependencies>  
  <dependency>  
    <groupId>myGroup</groupId>  
    <artifactId>myJar</artifactId>  
    <version>4.0</version>   
    <type>jar</type>  
    </dependency>    
  <dependency>  
    <groupId>myGroup</groupId>  
    <artifactId>myJar</artifactId>  
    <version>4.0</version>  
    <type>jar</type>  
    <classifier>sources</classifier>  
  </dependency>  
</dependencies>

当我从Windows资源管理器视图中打开myJar-4.0-sources.jar文件时，我看到其中的所有java源文件都与它相关联。但是当我在我的maven依赖项中查看我的eclipse项目时，我只看到xml文件而没有myJar-4.0-sources.jar的java文件

顺便说一下，无论我在eclipse或外部运行maven构建，它都抱怨没有应该在myJar-4.0-sources.jar中找到的类的源代码。

顺便说一句，这是一个GWT编译。

以下是实际的错误消息：

有人知道为什么会这样吗？

Answer 1

GWT在与编译的JAR相同的JAR中查找依赖项源类文件。由于图书馆是你最好的控制之下当然是包含类文件和源文件同样的JAR。为此，请向<resource>部分添加<build> POM（假设标准的Maven源布局）：

<project>
  <build>
    <resources>
      <resource>
        <directory>src/main/java</directory>
      </resource>
    </resources>
  </build>
</project>

GWT在与编译的类文件相同的JAR中查找依赖项源。您应该在同一个JAR中包含类文件和源文件。为此，请在POM的<resource>部分添加<build>：

<project>
  <build>
    <resources>
      <!-- include the source files in our main jar for use by GWT -->
      <resource>
        <directory>${project.build.sourceDirectory}</directory>
      </resource>
      <!-- and continue to include our standard resources -->
      <resource>
        <directory>${basedir}/src/main/resources</directory>
      </resource>
    </resources>
  </build>
</project>

我终于弄明白我的问题了。这是我的.gwt.xml文件。它没有正确引用GWT类。不是我解决了这个，我相信我想通过源jar文件引用我的源库的原始方式将起作用。感谢。

Maven - 添加源依赖;但是在eclipse中没有可用于GWT编译的java源文件
