我已经花了好几个小时来解决这个问题。

尝试编译Maven GWT项目，在GWT编译点遇到以下错误：

  

[INFO]编译模块com.ephesoft.dcma.gwt.login.Login
  [INFO]验证新编译的单位
  [INFO] [错误]'jar：file：/ D：/workspace2/dcma-root/dcma-gwt/dcma-gwt-core/target/dcma-gwt-core-0.0.14-> SNAPSHOT.jar！/com/ephesoft/dcma/gwt/core/client/validator/ValidatorFactory.java“
  [INFO] [ERROR]第47行：没有源代码可用于类型com.ephesoft.dcma.core.common.DataType;你忘了继承一个必要的模块吗？   [INFO] [错误]'jar：文件中的错误：/ D：/workspace2/dcma-root/dcma-gwt/dcma-gwt-core/target/dcma-gwt-core-0.0.14-SNAPSHOT.jar！/ COM / ephesoft / DCMA / GWT /核心/客户机/用户界面/ RotatableImage.java'
  [INFO] [ERROR]第54行：没有源代码可用于com.ephesoft.dcma.batch.schema.Direction类型;你忘了继承一个必要的模块吗？   [INFO] [错误]'jar：文件中的错误：/ D：/workspace2/dcma-root/dcma-gwt/dcma-gwt-core/target/dcma-gwt-core-0.0.14-SNAPSHOT.jar！/ COM / ephesoft / DCMA / GWT /型芯/共享/比较器/ DocumentTypeComparator.java'
  ...
  ......

并且列表继续......

这是我的webapp pom文件 -

所以Login包含Core，后者又包含Common，那么问题是什么？

我非常感谢你的帮助!!!

如果我理解你需要编译gwt-module这个问题，那么另一个问题是什么呢？对于我们在依赖模块中使用的任务

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>gwt-maven-plugin</artifactId>
    <version>${gwt.version}</version>
    <executions>
      <execution>
        <goals>
          <goal>compile</goal>
        </goals>
      </execution>
    </executions>
    <configuration>
      <extraJvmArgs>-Xmx1024M</extraJvmArgs>
      <localWorkers>3</localWorkers>
      <optimizationLevel>${gwt.optimize}</optimizationLevel>
      <style>OBF' -XenableClosureCompiler '-XenableClosureCompiler</style>
      <workDir>${project.build.directory}/gwt/temp</workDir>
      <deploy>${project.build.directory}/WEB-INF/deploy</deploy>
      <modules>
        <module>${module}</module>
      </modules>
      <hostedWebapp>${webappDirectory}</hostedWebapp>
      <logLevel>WARN</logLevel>
      <compileSourcesArtifacts>
        <compileSourcesArtifact>groupId:artifactId</compileSourcesArtifact>
      </compileSourcesArtifacts>
    </configuration>
  </plugin>

<compileSourcesArtifact>groupId:artifactId</compileSourcesArtifact>看起来像<compileSourcesArtifact>com.google.gwt:gwt-user</compileSourcesArtifact>和核心模块

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-source-plugin</artifactId>
    <executions>
      <execution>
        <id>attach-sources</id>
        <phase>package</phase>
        <goals>
          <goal>jar</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

要编译依赖于另一个Maven模块的GWT模块，我必须将依赖项显式地添加到依赖项的源中：

<dependency>
    <groupId>...</groupId>
    <artifactId>...</artifactId>
    <version>...</version>
    <classifier>sources</classifier>
    <scope>compile</scope>
</dependency>

当然也要像@Teymur所说的那样从依赖项部署源：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-source-plugin</artifactId>
    <version>3.2.0</version>
    <executions>
        <execution>
            <id>attach-sources</id>
            <phase>verify</phase>
            <goals>
                <goal>jar-no-fork</goal>
            </goals>
        </execution>
    </executions>
</plugin>

这没有<compileSourcesArtifacts>设置。
