Question

我在我的GWT网络应用中使用客户端验证，并使用Maven作为构建工具。在开发模式下运行不会导致任何问题。现在我想用Maven构建项目，但是会出现多个错误，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在编译项目时能看到jar源文件 hibernate-validator-4.2.0.Final-sources.jar 。如何管理此资源以使其工作？我试图将 hibernate-validator-4.2.0.Final-sources.jar 放入src/main/resources目录，但它似乎不起作用。

Answer 1

没有看到你的pom.xml，这有点难以说，但我的第一个假设是你忘了在你的pom中添加hibernate-validator-4.2.0.Final-sources.jar的依赖项或者存在版本控制问题。你能发贴你的pom吗？

知道了：

你有这种依赖

<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>

这是4.2.0.Final jar但你没有4.2.0.Final-sources.jar

添加最终来源的依赖关系，您应该得到答案。

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。

gwt-maven-plugin无法编译，因为“没有源代码可用于类型org.hibernate.validator.constraints.impl.SizeValidatorForString;”
