Question

我的问题似乎与问题Build Android Studio app via command line类似，但有点不同。我有一个android工作室项目，使用Android工作室IDE构建时一切正常但我需要通过 ubuntu 终端构建项目。我键入./gradlew build我收到以下错误：

A problem occurred configuring root project 'ContentProvider'.

无法解析配置'：classpath'的所有文件。无法解决com.android.tools.build:gradle:3.0.1。要求：项目：无法解决com.android.tools.build:gradle:3.0.1。无法获取资源“https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/3.0.1/gradle-3.0.1.pom”。无法获得“https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/3.0.1/gradle-3.0.1.pom”。 java.lang.RuntimeException：意外错误：java.security.InvalidAlgorithmParameterException：trustAnchors参数必须为非空无法解决com.android.tools.build:gradle:3.0.1。无法获取资源“https://jcenter.bintray.com/com/android/tools/build/gradle/3.0.1/gradle-3.0.1.pom”。无法获得“https://jcenter.bintray.com/com/android/tools/build/gradle/3.0.1/gradle-3.0.1.pom”。 java.lang.RuntimeException：意外错误：java.security.InvalidAlgorithmParameterException：trustAnchors参数必须为非空。

在输入sudo ./gradlew时，我收到了以下错误：

即使项目构建良好，也没有任何错误通过IDE。提前致谢

Answer 1

最后我解决了我的问题，解决方法如下： 1-安装jdk8：

sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt-get install openjdk-8-jdk
sudo update-alternatives --config java
sudo update-alternatives --config javac

确定java类型：

java -version

2-安装Gradle版本4.4.1（这对我来说很顺利）：

wget https://services.gradle.org/distributions/gradle-4.4.1-bin.zip
sudo mkdir /opt/gradle
sudo unzip -d /opt/gradle gradle-4.4.1-bin.zip
export PATH=$PATH:/opt/gradle/gradle-4.4.1/bin

确保gradle类型：

gradle -v

3-键入以下命令安装ca-certificates-java：

sudo apt install ca-certificates-java

4-重启你的电脑。

然后输入：

gradle build

如果您遇到如下错误：任务＆＃39;：app：lint＆＃39;。

的执行失败

将此添加到app模块的构建脚本中。

android {
  lintOptions {
      abortOnError false
  }
}

一切都应该顺利。

无法通过Ubuntu终端
