找不到 Gradle DSL 方法：使用 tesseract 库时出现“compile（）”

Question

我试图在Android Studio导入 tesseract ocr 项目。在构建 gradle 时，它显示错误如下

错误：（8， 0） 找不到 Gradle DSL 方法：“编译（）” 可能的原因：

我的设置.gradle 文件

    include ':libraries:tess-two'
include ':app'

My gradle-wrapper.properties

distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-2.2.1-all.zip

我也添加了依赖项。请告诉我问题出在哪里。谢谢

Answer 1

你必须改变你的顶级build.gradle，删除编译行，并添加gradle和fabric插件。

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
        jcenter()
    }
   dependencies {
        classpath 'com.android.tools.build:gradle:1.3.1'
        classpath 'io.fabric.tools:gradle:1.+'
    }
}


allprojects {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
        maven { url "http://dl.bintray.com/populov/maven" }
        jcenter()
        maven {
            url "http://oss.sonatype.org/content/repositories/snapshots"
        }

    }

}

Als 如果你想在你的项目中使用 libraries：tess-two，你必须在 app/build.gradle 文件的依赖块中添加这一行

compile project(':libraries:tess-two')

最后移动应用插件：在app/build.gradle文件的开头的'osgi'

要解决 ndk 问题，您必须：

1. 将 gradle.properties 文件添加到项目的根文件夹
2. 将 'android.useDeprecatedNdk=true' 添加到 gradle.properties file

这是我的 gradle.properties ：

android.useDeprecatedNdk=true
