我正在使用Kotlin研究Android Material Design,一切都很顺利,直到我尝试使用android.support.design.widget.FloatingActionButton.

当我重建项目时,我收到以下错误消息:

信息:Gradle任务[clean,:app:assembleDebug] C:\ Users\qin.gradle\caches\transforms-1\files-1.1\appcompat-v7-26.1.0.aar\3d5ddc383685b19d22429a29e09f2aeb\res\values\values.xml错误:(1419,5)错误:未找到样式属性'attr/textColor(aka br.com.conseng.themedesign:attr/textColor).错误:(1525,5)错误:未找到样式属性'attr/textColor(aka br.com.conseng.themedesign:attr/textColor)......\CursoMaterialDesign\ThemeDesign\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml错误:(1843)样式属性'attr/textColor(又名br.com.conseng.themedesign: attr/textColor)'找不到.错误:(1953)未找到样式属性'attr/textColor(aka br.com.conseng.themedesign:attr/textColor).错误:链接引用失败.错误:java.util.concurrent.ExecutionException:java.util.concurrent.ExecutionException:com.android.tools.aapt2.Aapt2Exception:AAPT2 error:check logs for details错误:java.util.concurrent.ExecutionException:com.android.tools .aapt2.Aapt2Exception:AAPT2错误:检查日志以获取详细信息错误:com.android.tools.aapt2.Aapt2Exception:AAPT2错误:检查日志以获取详细信息错误:任务':app:processDebugResources'的执行失败.无法执行aapt信息:15秒内建立失败信息:9错误信息:0警告信息:在控制台中查看完整输出

我在GitHub上保存了源文件,我的环境是:

• WINDOWS 10 10.03.0.1(64位)
• ANDROID STUDIO Android Studio 3.0.1 - Build#AI-171.4443003
• JRE:1.8.0_152-release-915-b01 amd64
• JVM:JetBrains sro的OpenJDK 64位服务器VM

我试过了:

1. FILE-> INVALIDATE CACHE/RESTART命令,但没有任何改变.

2. 我在终端上执行了gradlew cleanBuildCache,但它无法从'9.0.1'(？)确定java版本,如下所示.
