当我使用这个'dependencies' 时，一切都很好。应用运行。
应用程序依赖项:
dependencies {
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.android.support:design:23.0.1'
compile 'com.android.support:recyclerview-v7:23.0.1'
compile 'org.jsoup:jsoup:1.7.2'
compile 'com.mcxiaoke.volley:library:1.0.19'
}
但是当我在此应用程序中添加 java 模块依赖项 时，它会抛出错误:
Error:Execution failed for task ':app:dexDebug'. com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'D:\Java\jdk1.8.0_45\bin\java.exe'' finished with non-zero exit value 1
就这样
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "three.com.materialdesignexample"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile project(':securitycode')
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.android.support:design:23.0.1'
compile 'com.android.support:recyclerview-v7:23.0.1'
compile 'org.jsoup:jsoup:1.7.2'
compile 'com.mcxiaoke.volley:library:1.0.19'
}
我的 Java 模块依赖项没有任何内容
apply plugin: 'java'
dependencies {
}
那我该怎么办呢？

最佳答案
我也有 JDK 8。就我而言，我添加:
sourceCompatibility = JavaVersion.VERSION_1_7
targetCompatibility = JavaVersion.VERSION_1_7
到 Java 库模块，项目应该可以正常编译和工作。
关于Android Studio 当我在应用程序中添加 Java 模块时会出错，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33118057/
假设我做了一个模块如下:m=Module.newdoclassCendend三个问题:除了对m的引用之外，还有什么方法可以访问C和m中的其他内容？我可以在创建匿名模块后为其命名吗(就像我输入“module...”一样)？如何在使用完匿名模块后将其删除，使其定义的常量不再存在？ 最佳答案 三个答案:是的，使用ObjectSpace.此代码使c引用你的类(class)C不引用m:c=nilObjectSpace.each_object{|obj|c=objif(Class===objandobj.name=~/::C$/)}当然这取决于
作为我的Rails应用程序的一部分，我编写了一个小导入程序，它从我们的LDAP系统中吸取数据并将其塞入一个用户表中。不幸的是，与LDAP相关的代码在遍历我们的32K用户时泄漏了大量内存，我一直无法弄清楚如何解决这个问题。这个问题似乎在某种程度上与LDAP库有关，因为当我删除对LDAP内容的调用时，内存使用情况会很好地稳定下来。此外，不断增加的对象是Net::BER::BerIdentifiedString和Net::BER::BerIdentifiedArray，它们都是LDAP库的一部分。当我运行导入时，内存使用量最终达到超过1GB的峰值。如果问题存在，我需要找到一些方法来更正我的代
我需要在客户计算机上运行Ruby应用程序。通常需要几天才能完成(复制大备份文件)。问题是如果启用sleep，它会中断应用程序。否则，计算机将持续运行数周，直到我下次访问为止。有什么方法可以防止执行期间休眠并让Windows在执行后休眠吗？欢迎任何疯狂的想法;-) 最佳答案 Here建议使用SetThreadExecutionStateWinAPI函数，使应用程序能够通知系统它正在使用中，从而防止系统在应用程序运行时进入休眠状态或关闭显示。像这样的东西:require'Win32API'ES_AWAYMODE_REQUIRED=0x0
当我使用Bundler时，是否需要在我的Gemfile中将其列为依赖项？毕竟，我的代码中有些地方需要它。例如，当我进行Bundler设置时:require"bundler/setup" 最佳答案 没有。您可以尝试，但首先您必须用鞋带将自己抬离地面。 关于ruby-我需要将Bundler本身添加到Gemfile中吗？，我们在StackOverflow上找到一个类似的问题： https://stackoverflow.com/questions/4758609/
对于具有离线功能的智能手机应用程序，我正在为Xml文件创建单向文本同步。我希望我的服务器将增量/差异(例如GNU差异补丁)发送到目标设备。这是计划:Time=0Server:hasversion_1ofXmlfile(~800kiB)Client:hasversion_1ofXmlfile(~800kiB)Time=1Server:hasversion_1andversion_2ofXmlfile(each~800kiB)computesdeltaoftheseversions(=patch)(~10kiB)sendspatchtoClient(~10kiBtransferred)Cl

我想用ruby编写一个小的命令行实用程序并将其作为gem分发。我知道安装后，Guard、Sass和Thor等某些gem可以从命令行自行运行。为了让gem像二进制文件一样可用，我需要在我的gemspec中指定什么。 最佳答案 Gem::Specification.newdo|s|...s.executable='name_of_executable'...endhttp://docs.rubygems.org/read/chapter/20 关于ruby-在Ruby中编写命令行实用程序
