升级到gradle插件3.0.1后数据绑定生成期间的异常

Question

我将项目升级到Gradle插件3.0.1,但在生成数据绑定类期间,我收到以下错误(并且未生成绑定类):

error: cannot generate view binders java.lang.NullPointerException
        at android.databinding.tool.store.SetterStore.getMatchingMultiAttributeSetters(SetterStore.java:642)
        at android.databinding.tool.store.SetterStore.getMultiAttributeSetterCalls(SetterStore.java:529)
        at android.databinding.tool.BindingTarget.resolveMultiSetters(BindingTarget.java:221)
        at android.databinding.tool.LayoutBinder.<init>(LayoutBinder.java:249)
        at android.databinding.tool.DataBinder.<init>(DataBinder.java:52)
        at android.databinding.tool.CompilerChef.ensureDataBinder(CompilerChef.java:90)
        at android.databinding.tool.CompilerChef.sealModels(CompilerChef.java:203)
        at android.databinding.annotationprocessor.ProcessExpressions.writeResourceBundle(ProcessExpressions.java:193)
        at com.sun.tools.javac.processing.JavacProcessingEnvironment.callProcessor(JavacProcessingEnvironment.java:794)
        ...

经过一些调查后,如果我在布局xml中的给定元素上使用数据绑定最多有1个属性,那么似乎正确生成了绑定类.如果我添加第二个,我得到前一个异常.

在我的项目环境中,以下视图会导致错误,但不幸的是,在一个全新的项目中,它会正常编译.

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto">

    <data>
        <import type="android.view.View"/>

        <variable
            name="title"
            type="String"/>

        <variable
            name="visible"
            type="boolean"/>
    </data>

    <RelativeLayout android:layout_width="match_parent"
                    android:layout_height="match_parent">

        <!-- with either text or visiblility, the project builds, but not with both -->
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@{title}"
            android:visibility="@{visible ? View.VISIBLE : View.GONE}"
            />
    </RelativeLayout>
</layout>

有没有人遇到过这个问题？
