为什么在gradle：3.2.1上发生未知属性'bundleRelease'错误？

Question

从classpath 'com.android.tools.build:gradle:3.1.4'更新为classpath 'com.android.tools.build:gradle:3.2.1'

发生错误：

FAILURE: Build failed with an exception.

* What went wrong:
Exception thrown while executing model rule: PublishingPlugin.Rules#publishing(ExtensionContainer)
> Could not get unknown property 'bundleRelease' for object of type org.gradle.api.publish.maven.internal.publication.DefaultMavenPublication.

错误出现在文件 mavenCustom.gradle

中
