Gradle不尊重常春藤标准版要求

Question

在我的build.gradle文件中：

compile 'com.android.support:support-v4:[10.0.0,26.0.0['
compile 'com.android.support:appcompat-v7:[10.0.0,26.0.0['

正在运行gradle dependencies，显示：

sourcesReleaseCompile - Classpath for compiling the sourcesRelease sources.
+--- project :MyProject
|    +--- com.android.support:support-v4:[10.0.0,26.0.0[ -> 26.0.0-alpha1
[...]
|    \--- com.android.support:appcompat-v7:[10.0.0,26.0.0[ -> 26.0.0-alpha1

我想避免包括26.0.0-alpha1 ...为什么我们不遵守常春藤标准符号呢？

您的版本错误，26.0.0尚未发布。检查您在本地的版本：

$ ls ~/android-sdk/extras/android/m2repository/com/android/support/appcompat-v7/
18.0.0/                  22.1.1/                  23.4.0/                  25.0.1/
19.0.0/                  22.2.0/                  24.0.0/                  25.1.0/
19.0.1/                  22.2.1/                  24.0.0-alpha1/           25.1.1/
19.1.0/                  23.0.0/                  24.0.0-alpha2/           25.2.0/
20.0.0/                  23.0.1/                  24.0.0-beta1/            25.3.0/
21.0.0/                  23.1.0/                  24.1.0/                  25.3.1/
21.0.2/                  23.1.1/                  24.1.1/                  26.0.0-alpha1/
21.0.3/                  23.2.0/                  24.2.0/                  maven-metadata.xml
22.0.0/                  23.2.1/                  24.2.1/                  maven-metadata.xml.md5
22.1.0/                  23.3.0/                  25.0.0/                  maven-metadata.xml.sha1

由于26.0.0-alpha1已经用完，但26.0.0没有，因此您需要使用+。这适用于Gradle 3.5：

dependencies {
    compile 'com.android.support:support-v4:[10.0.0,26.0.+['
    compile 'com.android.support:appcompat-v7:[10.0.0,26.0.+['
}

可能与您的问题无关，但您的项目无法编译：

/Users/<>/repo/gradle-dependency-test/app/src/main/AndroidManifest.xml Error:
        uses-sdk:minSdkVersion 10 cannot be smaller than version 14 declared in library [com.android.support:appcompat-v7:26.0.0-alpha1] /Users/<>/.android/build-cache/72b0bd3c930a8826bf341b591250d185129357b9/output/AndroidManifest.xml

事实证明，这是您的minSdkVersion版本。在app/build.gradle中，将minSdkVersion设置为14：

android {
    defaultConfig {
        minSdkVersion 14
    }
}

compileSdkVersion 26立即发布
