Volley不适用于Gradle 2.0和Instant run

Question

我最近将Android Studio更新为2.0版：Beta 7。 我正在尝试使用Instant Run，我刚刚安装了Gradle 2.0。 但由于与bintray.gradle相关的错误

，现在我无法编译我的项目

编译时出现以下错误：

Error:Cannot configure the 'publishing' extension after it has been accessed.

调试器错误：

Error:FAILURE: Build failed with an exception.

* Where:
Script 'C:\Project\AtkApp\volley\bintray.gradle' line: 43

* What went wrong:
A problem occurred evaluating script.
> Cannot configure the 'publishing' extension after it has been accessed.

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

Bintray.gradle：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath "com.jfrog.bintray.gradle:gradle-bintray-plugin:1.2"
    }
}

// apply the plugin with its class name rather than its Id to work around gradle limitation of
// not being able to find the plugin by Id despite the dependencies being added right above. Gradle
// is currently not capable of loading plugins by Id if the dependency is anywhere else than
// in the main project build.gradle. This file is "imported" into the project's build.gradle
// through a "apply from:".
apply plugin: com.jfrog.bintray.gradle.BintrayPlugin
apply plugin: 'maven-publish'

project.ext.group = 'com.android.volley'
project.ext.archivesBaseName = 'volley'

        }
    }
}

        version {
            name = project.ext.version
            desc = project.ext.pomDesc + ' version ' + project.ext.version
            gpg {
                sign = true

Answer 1

我在更新最新版本时遇到了同样的问题。 我尝试过这样做并取得成功。

Answer 2

罪魁祸首是Volley项目publishing中使用的bintray.gradle标记。 使用Gradle 2.0.0更新后，无法在访问publishing后对其进行配置抱怨。

现在评论build.gradle Volley项目的//apply from: 'bintray.gradle' 中的以下行将进行构建。

我会更新评论一次有更好的解决方案。

Answer 3

不要评论这一行：

var express = require('express');
var fs = require('fs');
var app = express();

var util = require('util');
var mongoose = require('mongoose');
var schema = mongoose.Schema;

var studSchema = new schema({
    id  : {type:Number, unique:true, required:true},
    name : {type:String, required:true},
    grade : Number,
    course : {type:String},
    year : Number
},{collection: 'details'});

var stud = mongoose.model('stud', studSchema);

module.exports = function (app) {
    app.get('/getAll', function(req, res) { // if url in path is getAll
     stud.find({}, function(err, user){
        if(err) throw err;
        console.log(user);
     });
    })
});

只需更改这些代码行

apply from: 'bintray.gradle'

到

publishing {
publications {
    library(MavenPublication) {
        groupId project.ext.group
        artifactId project.ext.archivesBaseName
        version project.ext.version

        // Release AAR, Sources, and JavaDoc
        artifact "$buildDir/outputs/aar/volley-release.aar"
        artifact sourcesJar
        artifact javadocJar
    }
}
}

发布{publications {}}，它位于您添加到项目中的排球文件中。不要浪费时间在项目中找工作。
