当我尝试使用gradle构建我的Android应用时,我收到了一个奇怪的错误。
我尝试运行gradle build
时出现此错误:
Could not find method buildToolsVersion() for arguments [23.0.2] on root project 'latest'.
但是,我检查了我的android SDK文件夹,看看这个版本是否真的丢失了。换句话说,发布ls $ANDROID_HOME/build-tools/
的结果是:
19.1.0 20.0.0 21.1.2 22.0.1 23.0.1 23.0.2 23.0.3
如您所见,23.0.2
存在。什么似乎是问题?
这是我的根build.gradle
文件:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.0.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
mavenCentral()
}
}
ext {
compileSdkVersion 23
buildToolsVersion '23.0.2'
}
subprojects { subproject ->
afterEvaluate{
if((subproject.plugins.hasPlugin('android') || subproject.plugins.hasPlugin('android-library'))) {
android {
compileSdkVersion rootProject.ext.compileSdkVersion
buildToolsVersion rootProject.ext.buildToolsVersion
}
}
}
}
这是build.gradle
文件
apply plugin: 'com.android.application'
apply from: 'copyLibs.gradle'
apply plugin: 'eclipse'
android {
compileSdkVersion rootProject.ext.compileSdkVersion
buildToolsVersion rootProject.ext.buildToolsVersion
defaultConfig {

targetSdkVersion 23
versionCode 35

}
compileOptions {

targetCompatibility JavaVersion.VERSION_1_7
}
// avoid Travis failures

}
}
dependencies {
compile 'com.android.support:appcompat-v7:22.0.0'
compile 'com.android.support:recyclerview-v7:22.0.0'

}
tasks.findAll {

您看到这个的原因是因为您在根项目中声明的变量缺少分配。
ext {
compileSdkVersion 23
buildToolsVersion '23.0.2'
}
应该是:
ext {
compileSdkVersion = 23
buildToolsVersion = '23.0.2'
}

如果您有很多Android模块,您可能希望避免在所有模块中手动设置相同的值。因为你可能混合了android和android-library项目,你不能通过子项目闭包应用这些插件。但是,您可以在根项目上设置值,然后从模块中引用它。
您似乎无法在subprojects
区块中使用它。
解决方法是在顶级文件中声明:
ext {
compileSdkVersion 23
buildToolsVersion "23.0.2"
}
然后在所有模块中使用:
android {
compileSdkVersion rootProject.ext.compileSdkVersion
buildToolsVersion rootProject.ext.buildToolsVersion
}
