我在将Lucene 6.2.0添加到我的Android Studio 2.1.2项目时遇到问题。但是，将这个库添加到IntelliJ IDEA不是问题。我尝试将Lucene文件复制到我的libs文件夹，然后添加列为here作为库的jar文件（右键单击=>添加为库）。 的build.gradle看起来很不错：将Lucene添加到Android Studio项目
compile files('libs/lucene-6.2.0/queryparser/lucene-queryparser-6.2.0.jar')
compile files('libs/lucene-6.2.0/demo/lucene-demo-6.2.0.jar')
compile files('libs/lucene-6.2.0/core/lucene-core-6.2.0.jar')
compile files('libs/lucene-6.2.0/analysis/common/lucene-analyzers-common-6.2.0.jar')

To run dex in process, the Gradle daemon needs a larger heap.
It currently has approximately 910 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB.
To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties.
For more information see https://docs.gradle.org/current/userguide/build_environment.html

我也试过这样：
compile fileTree(dir: 'libs', include: '*.jar')
我的应用程序运行，没有任何错误，但Lucene的类无法识别。
我在做什么错了？
