Error:Plugin requires 'APK Signature Scheme v2 Enabled' for sourceSets. 怎么解决啊

[achellies]

加上--stacktrace把详细的日志信息发出来， 一般这种情况是未开启V2签名或者V2签名被破坏了

[achellies]

            if (!isV2SignatureSchemeEnabled(variant)) {
                throw new ProjectConfigurationException("Plugin requires 'APK Signature Scheme v2 Enabled' for ${variant.name}.", null);
            }

Signature Scheme v2 Enabled 在gradle2.2之后是自动开启的不是么

[zhengzhuoxing]

Android 7.0 引入一项新的应用签名方案 APK Signature Scheme v2，它能提供更快的应用安装时间和更多针对未授权 APK 文件更改的保护。在默认情况下，Android Studio 2.2 和 Android Plugin for Gradle 2.2 会使用 APK Signature Scheme v2 和传统签名方案来签署您的应用。 我并没有手动去关闭它啊

[achellies]

build.gradle里开启V2签名了吗？或者把walle注释掉，打一个包看看是否有签名区(在Apk文件中通过字符串查找 “APK Sig Block 42”)

[zhengzhuoxing]

在Apk中有 APK Sig Block 42PK，但是我这还是提示未开启 APK Signature Scheme v2

[achellies]

       project.afterEvaluate {
            project.android.applicationVariants.all { BaseVariant variant ->
                def variantName = variant.name.capitalize();

                if (!isV2SignatureSchemeEnabled(variant)) {
                    throw new ProjectConfigurationException("Plugin requires 'APK Signature Scheme v2 Enabled' for ${variant.name}.", null);
                }

            }
        }

 boolean isV2SignatureSchemeEnabled(BaseVariant variant) throws GradleException {
        def signingConfig = getSigningConfig(variant);
        if (signingConfig == null || !signingConfig.isSigningReady()) {
            return false;
        }

        // check whether APK Signature Scheme v2 is enabled.
        if (signingConfig.hasProperty("v2SigningEnabled") &&
                signingConfig.v2SigningEnabled == true) {
            return true;
        }

        return false;
    }

这个是判断逻辑， 把这段贴到项目的build.gradle中跑下看看是否会出错

[zhengzhuoxing]

BaseVariant 找不到

[achellies]

com.android.build.gradle.api.BaseVariant

[zhengzhuoxing]

把这段代码添加上之后 还是报 这个错 Error:Plugin requires 'APK Signature Scheme v2 Enabled' for sourceSets.

[achellies]

SigningConfig getSigningConfig(BaseVariant variant) {
        return variant.buildType.signingConfig == null ? variant.mergedFlavor.signingConfig : variant.buildType.signingConfig;
    }
 def signingConfig = getSigningConfig(variant);
        if (signingConfig == null || !signingConfig.isSigningReady()) {
            return false;
        }

        // check whether APK Signature Scheme v2 is enabled.
        if (signingConfig.hasProperty("v2SigningEnabled") &&
                signingConfig.v2SigningEnabled == true) {
            return true;
        }

        return false;

这个条件满足吗？

[zhengzhuoxing]

Error:(102, 0) Could not find method getSigningConfig() for arguments [com.android.build.gradle.internal.api.ApplicationVariantImpl_Decorated@7c88a66e] on project 找不到这个方法

[achellies]

加上这个

SigningConfig getSigningConfig(BaseVariant variant) {
        return variant.buildType.signingConfig == null ? variant.mergedFlavor.signingConfig : variant.buildType.signingConfig;
    }

[zhengzhuoxing]

是不是说明我开启 v2了

[zhengzhuoxing]

我用命令行打包了，不用配置gradle了 谢谢你的帮助

[jack-github]

这个问题怎么解决的啊？
