java - 编译 AIDL 时出错

Question

我正在尝试编译 .aidl 并生成 .java 但是:

Error:Execution failed for task ':library:compileReleaseAidl'.
> java.lang.RuntimeException: com.android.ide.common.process.ProcessException:

我用这个build.gradle

apply plugin: 'com.android.library'
apply plugin: 'com.github.dcendents.android-maven'

group='com.github.michelelacorte'

android {
    compileSdkVersion 25
    buildToolsVersion '25.0.0'

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 25
        versionCode 2
        versionName "0.2.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }

    sourceSets {
        main {
            aidl.srcDirs = ['src/main/aidl']
        }
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.0.1'
    testCompile 'junit:junit:4.12'
    compile 'com.google.code.gson:gson:2.8.0'
}

还有这个根 build.gradle

// 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:2.2.3'
        classpath 'com.github.dcendents:android-maven-gradle-plugin:1.5'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

我读过关于构建工具的问题，但我没有找到任何关于 API 25 的信息

编辑:

我用参数启动了 aidl.exe 并返回:

aidl.exe E  2236 13884 aidl_language.cpp:224] Error while opening file for parsing: 'C:\Users\Michele\workspace\AndroidLib\library\src\IRemoteShortcutService.aidl'

编辑 2:

Shortcut.aidl

// Shortcut.aidl
package it.michelelacorte.androidshortcuts;

parcelable Shortcuts;

IRemoteShortcutService.aidl

// IRemoteShortcutService.aidl
package it.michelelacorte.androidshortcuts;

interface IRemoteShortcutService {

    void addShortcuts(int shortcutsImage, String shortcutsText);

    Shortcuts getShortcuts();
}

这个.aidl 位于src/main/aidl 文件夹

Answer 1

您是否尝试向 gradle 添加详细选项或使用相同参数手动执行相同的 aidl.exe？

可能存在 gradle 未显示的来自 aidl.exe 的解释性错误代码或消息。

根据aidl的错误无法打开文件。检查文件是否存在以及内容是否有效。

尝试更改为新的默认布局:

将aidl文件放在/src/main/aidl

build.gradle:

...
    sourceSets {
        main {
            aidl.srcDirs = ['src/main/aidl']
        }
    }

(尽管，一般来说，如果文件在 /src/main/aidl 中，它应该在没有 aidl.srcDirs 条目的情况下工作)

不要忘记 aidl 文件应该在包文件夹下，例如 java.lang.例如，如果包是 it.michelelacorte.testaidl，则 aidl 文件应该位于 src/main/aidl/it/michelelacorte/testaidl 下。

在最新版本的 Android Studio 中，如果项目包设置正确，New/AIDL/AIDL File 项目菜单应该已经将文件放置在正确的文件夹下。
