每当我尝试assemble调试应用程序的构建时，更新到gradle 2.10后，我得到NoSuchMethodError异常。以下是构建日志的相关部分：

java.lang.RuntimeException: failure, see logs for details.

如您所见，无法找到方法com.google.common.base.Strings.isNullOrEmpty。

某些细节

我使用了Retrolambda 3.2.5和Java 8.没有其他额外的插件。

构建插件版本：com.android.tools.build:gradle:2.0.0

构建工具版本：23.0.3

操作系统：OS X

build.gradle看起来像这样。我稍微改了一下，不露出一些私密的东西，但问题仍然存在。

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }

        classpath 'me.tatarka:gradle-retrolambda:3.2.3'
    }
}

        it.name.startsWith('dex')

        if (dx.additionalParameters == null) {
            dx.additionalParameters = []
        }
        dx.additionalParameters += "--set-max-idx-number=50000" //    default 60000

您是否尝试过类似问题＃134 clean-build的jitpack上的新补丁，gradle导入订单似乎有问题，您可以尝试使用：

repositories {
    maven { url "https://jitpack.io" }
}
dependencies {
    classpath 'com.github.denis-itskovich:gradle-retrolambda:3.2.3-fix-134'
}

答案 1 :(得分：0)

升级Android Studio后，看起来插件出现了错误。

如果您进入：<Android Studio Dir>/plugins/android/lib/builder-model-x.x.x.jar，您可能会找到2个.jars。尝试删除旧版本.jar并保留新版本并清理并重建项目。

如果上述方法不起作用，请尝试以下方法：

将后端的build.gradle文件中的Objectify库版本更改为4.0b或更高版本（如果存在）。

这可能听起来无关紧要，但是客体化4.0b库具有相同的包名，这些类包含在com.google.common.base.Strings.isNullOrEmpty等appengine sdk中。

当你部署app后端时，appengine类会被objectify类覆盖，因此当你尝试调用某个方法时会抛出错误。

这是在客观化5.0。+

中解决的

希望它有所帮助，因为它帮助我解决了这个问题。
