gwt-maven-plugin无法编译，因为“org.hibernate.validator.constraints.impl.SizeValidatorForString;”类型没有可用的源代码

Question

我在我的GWT web应用程序中使用客户端验证，Maven作为构建工具。在dev模式下运行不会造成任何问题。现在我想用Maven构建这个项目，但是得到多个错误，如下所示：

[ERROR] Line 52: No source code is available for type org.hibernate.validator.constraints.impl.SizeValidatorForString; did you forget to inherit a required module?
[INFO]       [ERROR] Line 52: No source code is available for type org.hibernate.validator.constraints.impl.SizeValidatorForCollection; did you forget to inherit a required module?
[INFO]       [ERROR] Line 52: No source code is available for type org.hibernate.validator.constraints.impl.SizeValidatorForMap; did you forget to inherit a required module?
[INFO]       [ERROR] Line 75: No source code is available for type org.hibernate.validator.constraints.impl.NotNullValidator; did you forget to inherit a required module?
[INFO]       [ERROR] Line 83: No source code is available for type org.hibernate.validator.constraints.NotEmpty; did you forget to inherit a required module?

我希望gwt-maven-plugin在编译项目时能够看到jar源文件gwt-maven-plugin。如何管理此资源以使其工作？我试图将hibernate-validator-4.2.0.Final-sources.jar放到src/main/resources目录中，但它似乎不起作用。

在添加hibernate-validator-4.2.0.Final-sources.jar之后，hibernate验证器-4.2.0，#en0#Sourcees.jar mvn干净的安装结果如下：

Answer 1

没有看到您的pom.xml，这有点难说，但我的第一个假设是，您忘了在pom中添加hibernate-验证器-4.2.0.final-Sourcees.jar的依赖项，否则就会出现版本控制问题。你能把你的邮筒寄出去吗？

明白了：

你有这种依赖性

<dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-validator</artifactId>
        <scope>system</scope>
        <systemPath>${basedir}/war/WEB-INF/lib/hibernate-validator-4.2.0.Final.jar</systemPath>
    </dependency>

它是4.2.0，sources.jar，但是您没有4.2.0.final-Sourcees.jar

添加最终源的依赖项，您就会得到答案。

Answer 2

您需要Hibernate Validator 4.1 (不是4.0，而不是4.2)。

请参阅https://code.google.com/p/google-web-toolkit/issues/detail?id=7661

注意:显然，对于服务器端验证，您可以使用任何版本的Hibernate Validator。

Answer 3

您需要在类路径中包含both:hibernate-validator-4.2.0.Final-sources.jar和hibernate-验证器-4.2.0.Final.jar

只需在pom.xml中添加以下内容：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>4.2.0.Final</version>
    <classifier>sources</classifier>
    <scope>compile</scope>
</dependency>
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>4.2.0.Final</version>
</dependency>
