Question

我已经从Canary 9更新到Android Studio到Beta 1，我在打开项目时遇到了这个错误。

我已经使缓存失效并重启但不幸运。

我的gradle文件：

buildscript {
    ext.kotlin_version = '1.1.3'
    repositories {
        google()
        jcenter()
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-beta1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'io.fabric.tools:gradle:1.+'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
        maven { url "https://jitpack.io" }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

错误：原因：java.lang.NullPointerException at sun.nio.fs.UnixPath.normalizeAndCheck（UnixPath.java:77）at sun.nio.fs.UnixPath。（UnixPath.java:71）at sun.nio.fs.UnixFileSystem.getPath（UnixFileSystem.java:281）at
