无法理解gradle build -Xlint:unchecked中的错误

Question

我在使用gradle构建hibernate时遇到了这个错误

:hibernate-entitymanager:compileTestJava
/home/jsiddharth/workspace/hibernate-orm-master/hibernate-entitymanager/src/test/java/org/hibernate/jpa/test/criteria/paths/SingularAttributeJoinTest.java:128: error: <anonymous org.hibernate.jpa.test.criteria.paths.SingularAttributeJoinTest$2> is not abstract and does not override abstract method integrate(MetadataImplementor,SessionFactoryImplementor,SessionFactoryServiceRegistry) in Integrator
        return new Integrator() {
                                ^

:hibernate-entitymanager:compileTestJava FAILED

FAILURE: Build failed with an exception.

我以为我需要使用-Xlint选项运行gradle，但结果是，我做错了。我跑的时候出了这个错误

./gradlew -Xlint:deprecation -Xlint:unchecked Maven settings.xml文件不存在:/home/jsiddharth/.m2/setings.xml

FAILURE: Build failed with an exception.

* What went wrong:
Problem configuring task :eclipse from command line. Unknown command-line option '-X'.
> Unknown command-line option '-X'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

如何运行我的构建来忽略错误？

Answer 1

至于您的问题，-Xlint是一个Java编译器选项，与Gradle无关。您可以通过GRADLE_OPTS指定这些选项，这就是Gradle将参数传递给JVM的方式。

具体来说：GRADLE_OPTS="-Xlint:deprecation"

不管怎样，这不是你的麻烦。请看一下错误：

SingularAttributeJoinTest$2>不是抽象的，也不覆盖Integrator中的抽象方法集成(MetadataImplementor、SessionFactoryImplementor、SessionFactoryServiceRegistry)返回新的Integrator() {

在SingularAttributeJoinTest中有一个匿名类，该类被声明为实现Integrator，但未能实现方法integrate，且未声明为抽象。当然，-Xlint选项不能抑制这种错误。
