java - 无法在 NetBeans 中构建 GWT 项目

Question

我有一个基于 Maven 的 GWT 项目(GWTApplication)，其中包括两个 Java 库(也是基于 Maven 的) - 实体和元数据 em>.

实体的pom.xml:

<groupId>com.gfa.gwt</groupId>
<artifactId>gwt-entity</artifactId>
<packaging>jar</packaging>
<version>0.1</version>

元数据的pom.xml:

<groupId>com.gfa.gwt</groupId>
<artifactId>gwt-metadata</artifactId>
<packaging>jar</packaging>
<version>0.1</version>

主项目的pom.xml:

<dependencies>
 <dependency>
  <groupId>com.gfa.gwt</groupId>
  <artifactId>gwt-metadata</artifactId>
  <version>0.1</version>
 </dependency>

 <dependency>
  <groupId>com.gfa.gwt</groupId>
  <artifactId>gwt-entity</artifactId>
  <version>0.1</version>
 </dependency>
...
</dependencies>

当我尝试编译此项目(清理和构建)时，输出显示错误:

Compiling module test.application.Application Validating newly compiled units Ignored 42 units with compilation errors in first pass.

当然我在*.gwt.xml文件中继承了这些模块:

<inherits name="com.gfa.gwt.metadata.MetaData"/>
<inherits name="com.gfa.gwt.entity.Entity"/>

在 Eclipse 中，该项目编译没有问题，但在 NetBeans 中编译期间我看到了这些错误。我错过了什么吗？

感谢您的帮助。

您应该将 java 类包含到您的 gwt-metadata jar 文件中。添加到pom(gwt-元数据):

<build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/client/**</include>
                    <include>**/shared/**</include>
                    <include>**/*.gwt.xml</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
            </resource>
        </resources>
    </build>

或

<plugins>
<plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>gwt-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <phase>test</phase>
                        <goals>
                            <goal>resources</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
