我是科尔多瓦的新手 . 我安装了Android Studio 2.2.1和Cordova 6.3.1 . 我的Java版本是1.7.0_111 . 我创建了一个新的Cordova项目并添加了平台：android，cordova-plugin-dialogs和cordova-plugin-network-information . 然后我尝试构建项目但是我收到了一个错误：
xxxxxx@yyyyyyy ~/cordova/myapp $ cordova build
ANDROID_HOME=/home/xxxxxx/Android/Sdk
JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64
Incremental java compilation is an incubating feature.

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

我尝试将“multiDexEnabled true”添加到我的build.gradle文件中，但是我又遇到了另一个错误：“transformClassesWithMultidexlistForDebug FAILED” . 我也尝试清理Cordova项目，但它对错误没有任何影响 .
