java.lang.RuntimeException: The RequestFactory ValidationTool must be run

Question

I have been bogged down by this whole day. I went through almost all the links available for this issue. I also followed the instructions on https://code.google.com/p/google-web-toolkit/wiki/RequestFactoryInterfaceValidation#ValidationTool

I still am getting that error no idea why.

I am just going crazy here. Please help. Is there anything else that am missing here??

Answer 1

As mentioned in comments you need to have "YourRequestFactory"DeobfuscatorBuilder.class file in order to run it. I had similar problem and wanted non-Eclipse dependent solution. I solved it with:

        <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>

Another option is to use the com.google.web.bindery.requestfactory.apt.ValidationTool tool directly. You need to run it from JDK java (not JRE) and to have

requestfactory-apt-2.5.1.jar
requestfactory-server-2.5.1.jar
your wanna-be RequestFactory classes and their dependencies

on classpath. Replace 2.5.1 with ${gwtVersion}. You run it simply

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

Example for windows .bat file (cd-ed to JDK directory to run JDk java instead of 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"

Also even though I am not Maven guru I am not sure if having double maven-compiler-plugin declaration in Maven could not somehow contribute to validation not being run when building.

Answer 2

To get things work in maven-compiler-plugin 3.* you need one extra configuration key: forceJavacCompilerUse. The full example may look like this:

<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>

You doesn't event need the annotationProcessors configuration section because maven-compiler-plugin can automatically discover and apply RequestFactory annotation processing tool.

Answer 3

It seems this problem happens when the GWT application is started from Eclipse or another IDE. In maven I haven't seen it.

The way to workaround the problem is to start the application with Maven to create the xxx.yyyDeobfuscatorBuilder class and then you can launch your GWT app from Eclipse without problems
