我在离线模式中使用Android Studio 2.2
和Gradle
。 Gradle Home
的值为/path/to/gradle/gradle-2.14.1
。我可以运行Android项目,但现在我想运行Java标准类来测试一些Java代码,然后再在Android项目中使用它们。所以我跟着this answer。但是当我上课时,我得到了这样的错误:
Error:Gradle: A problem occurred configuring root project 'demo'.
> Could not resolve all dependencies for configuration ':classpath'.
> Could not resolve com.android.tools.build:gradle:2.2.2.
Required by:
:demo:unspecified
> No cached version of com.android.tools.build:gradle:2.2.2 available for offline mode.
此处还有Java库build.gradle
的内容:
apply plugin: 'java'
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
}
sourceCompatibility = "1.7"
targetCompatibility = "1.7"
我如何解决这个问题? (我不想使用其他IDE或为Gradle启用在线模式)
答案 0 :(得分:2)
您必须下载com.android.tools.build:gradle:2.2.2
...
这需要互联网。包gradle-2.14.1
与that is Gradle itself, and not the Android Gradle plugin不同。
但是,目前尚不清楚为什么要在标准Java模块上应用该插件。
你需要的只是
apply plugin: 'java'
换句话说,Gradle只是构建Android代码。除此之外,它与Android无关,如果正确设置,您可以独立于Android运行Java项目。
例如,
<强> java-code/build.gradle
强>
apply plugin: 'java'
targetCompatibility = '1.7'
sourceCompatibility = '1.7'
test {
testLogging {
// Show that tests are run in the command-line output
events 'passed'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
}
<强> app/build.gradle
强>
apply plugin: 'com.android.application'
evaluationDependsOn(':java-code')
...
dependencies {
compile project(":java-code")
compile fileTree(dir: 'libs', include: ['*.jar'])
...
}
<强> settings.gradle
强>
include ':app', ':java-code'
