java - Flutter Gradle 构建失败，出现异常

Question

在我们代理背后的公司中，我无法启动 flutter 项目。我没有运行 gradle。

我将此配置设置到 gradle.properties 中:

systemProp.http.proxyHost=http://my.company.com
systemProp.http.proxyPort=8080
systemProp.http.nonProxyHosts=127.0.0.1|localhost
systemProp.https.proxyHost=http://my.company.com
systemProp.https.proxyPort=8080
systemProp.https.nonProxyHosts=127.0.0.1|localhost

SSL 加密流量将被解密。我们的代理服务器上有自签名证书。我找不到任何方法告诉 gradle 我的 certs.pem 文件的路径。

Answer 1

编辑 gradle/wrapper/gradle-wrapper.properties 并更新到 Gradle 4.4 或 4.5:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.5-all.zip

还要确保 buildscript 添加了存储库 google()。

documentation不提供设置证书的选项。
