gwt - java.lang.RuntimeException：必须运行 RequestFactory ValidationTool

Question

我被这一天困住了。我浏览了几乎所有可用于此问题的链接。我还按照https://code.google.com/p/google-web-toolkit/wiki/RequestFactoryInterfaceValidation#ValidationTool上的说明进行操作

我仍然收到该错误，不知道为什么。

我只是在这里发疯。请帮忙。这里还有什么遗漏的吗？

这是我的 pom.xml

如评论中所述，您需要拥有“YourRequestFactory”DeobfuscatorBuilder.class 文件才能运行它。我有类似的问题，想要非 Eclipse 依赖的解决方案。我解决了它：

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.5.1</version>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
                <annotationProcessors>
                     <annotationProcessor>com.google.web.bindery.requestfactory.apt.RfValidator</annotationProcessor>
                </annotationProcessors>
            </configuration>
            <dependencies>
                <dependency>
                    <groupId>com.google.web.bindery</groupId>
                    <artifactId>requestfactory-apt</artifactId>
                    <version>${gwtVersion}</version>
                </dependency>
            </dependencies>
        </plugin>

另一种选择是com.google.web.bindery.requestfactory.apt.ValidationTool直接使用该工具。您需要从 JDK java（不是 JRE）运行它并拥有

requestfactory-apt-2.5.1.jar requestfactory
-server-2.5.1.jar
你想要的 RequestFactory 类及其依赖项

在类路径上。将 2.5.1 替换为 ${gwtVersion}。你简单地运行它

java -cp <your_set_classpath> com.google.web.bindery.requestfactory.apt.ValidationTool <your wanna-be RequestFactory class to be validated> <another wannae-be factory>...

windows .bat 文件的示例（cd 到 JDK 目录以运行 JDK java 而不是 JRE java）：

set loc=d:\coding\java\workspace\j2ee\beg_1\Allo\web\src\main\java\
set tool=d:\coding\tools\Maven\.m2\repository\com\google\web\bindery\requestfactory-apt\2.5.1\requestfactory-apt-2.5.1.jar
set server=d:\coding\tools\Maven\.m2\repository\com\google\web\bindery\requestfactory-server\2.5.1\requestfactory-server-2.5.1.jar
set lib=d:\coding\tools\Maven\.m2\repository\bbc\juniperus\allo-entities\1.0\allo-entities-1.0.jar
set lib2=d:\coding\tools\Maven\.m2\repository\org\hibernate\javax\persistence\hibernate-jpa-2.0-api\1.0.1.Final\hibernate-jpa-2.0-api-1.0.1.Final.jar

set CP=%loc%;%tool%;%server%;%lib%;%lib2%

cd %JAVA_HOME%/bin

java -cp %CP% com.google.web.bindery.requestfactory.apt.ValidationTool d:/output.jar bbc.juniperus.allo.web.gwt.client.CalendarRequestFactory"

此外，即使我不是 Maven 专家，我也不确定是否在 Maven 中拥有双重 maven-compiler-plugin 声明是否会导致在构建时不运行验证。

要在maven-compiler-plugin 3.*中运行，您需要一个额外的配置密钥：forceJavacCompilerUse. 完整的示例可能如下所示：

<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.1</version> <configuration> <forceJavacCompilerUse>true</forceJavacCompilerUse> </configuration> <dependencies> <dependency> <groupId>com.google.web.bindery</groupId> <artifactId>requestfactory-apt</artifactId> <version>2.6.1</version> </dependency> </dependencies> </plugin>

您不需要annotationProcessors配置部分，因为maven-compiler-plugin可以自动发现和应用 RequestFactory 注释处理工具。

当 GWT 应用程序从 Eclipse 或其他 IDE 启动时，似乎会发生此问题。在maven中我还没有看到它。

解决该问题的方法是使用 Maven 启动应用程序以创建xxx.yyyDeobfuscatorBuilder类，然后您可以从 Eclipse 启动 GWT 应用程序而不会出现问题
