摇篮绝对/相对路径 [英] Gradle absolute / relative path

问题描述

我有以下问题.当我想在Gradle依赖项中使用本地jar时.

I have the following problem. When I want to use a local jar in my Gradle dependencies.

如果我只添加:

compile files('libs/PushLinkAndroid-5.3.0.jar')

它不起作用.

C:\ Users \ Kai \ AndroidStudioProjects \ ProjectA \ app \ src \ main \ java \ de \ xyz \ xxx \ projecta \ BaseActivity.java:21:错误:包com.pushlink.android不存在导入com.pushlink.android.PushLink;

C:\Users\Kai\AndroidStudioProjects\ProjectA\app\src\main\java\de\xyz\xxx\projecta\BaseActivity.java:21: error: package com.pushlink.android does not exist import com.pushlink.android.PushLink;

注意:某些输入文件使用或覆盖不推荐使用的API.注意:有关详细信息，请使用-Xlint:deprecation重新编译.4个错误

Note: Some input files use or override a deprecated API. Note: Recompile with -Xlint:deprecation for details. 4 errors

失败

失败:构建失败，并出现异常.

FAILURE: Build failed with an exception.

• 出了什么问题:任务':app:compileDebugJava'的执行失败.

• What went wrong: Execution failed for task ':app:compileDebugJava'.

编译失败；有关详细信息，请参见编译器错误输出.

Compilation failed; see the compiler error output for details.

尝试:使用--stacktrace选项运行以获取堆栈跟踪.使用--info或>-debug选项运行，以获取更多日志输出.

Try: Run with --stacktrace option to get the stack trace. Run with --info or >--debug option to get more log output.

如果我将绝对路径添加到Jar中，则项目将编译，并且一切正常:

If i add the absolute path to the Jar, the project compiles and everything works finde:

compile files('C:/Users/Kai/AndroidStudioProjects/ProjectA/libs/PushLinkAndroid-5.3.0.jar')

看起来Path出了点问题，但是当绝对Path正常工作时怎么可能呢?

Looks like there is something wrong with the Path but how could this be when the absolute Path works fine?

Build.gradle

Build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "de.xyz.kai.migraenebook"
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    //compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.jakewharton:butterknife:7.0.1'
    compile project(':volley')
    debugCompile 'im.dino:dbinspector:3.2.1@aar'
    compile 'de.hdodenhof:circleimageview:1.3.0'
    compile 'com.android.support:recyclerview-v7:+'
    //compile files('C:/Users/Kai/AndroidStudioProjects/MigraeneBook/libs/PushLinkAndroid-5.3.0.jar')
    compile files('libs/PushLinkAndroid-5.3.0.jar')
    //compile files('libraries/PushLinkAndroid-5.3.0.jar')
    //compile files('C:/Users/Kai/AndroidStudioProjects/MigraeneBook/libraries/PushLinkAndroid-5.3.0.jar')
}

注意:我尝试了其他文件夹，PushLink.jar位于库"和库"中.我使用或注释掉的命令没有区别-绝对路径有效，相对路径无效.

NOTE: I tried different folders, the PushLink.jar is in "libs" and "libraries". It doesn't make a difference which command I use or comment out - absolute path is working, relative not.

推荐答案

尝试一下，它将包括本地存储库中的所有JAR，因此您不必每次都指定它:

Try this, it would include all JARs in the local repository, so you wouldn't have to specify it every time:

dependencies {
   compile fileTree(dir: 'libs', include: ['*.jar'])
}

此外，您应该知道在通过引用文件时

Also, you should know that when referencing a file via

files("relative/path/to/a.jar")

路径是相对于此片段所在的构建脚本进行评估的.因此，当您的 build.gradle 文件位于/a/project/build.gradle 中时，jar应该位于/a/project/relative/path/to/a.jar 中.在多项目gradle构建中，您可以将jar放在相对于根-项目的文件夹中，并通过

path is evaluated relative to the buildscript this snippet is in. So when your build.gradle file is located in /a/project/build.gradle, then the jar should be in /a/project/relative/path/to/a.jar. In a multiproject gradle build you can put the the jar in a folder relative to the root - project and reference it in all subprojects via

rootProject.files("relative/to/root/a.jar")

因此请考虑到这一点，然后重新检查gradle设置是否正确.

So take this to account and re-check if your gradle settings are correct.
