重新安装JDK

Question

我通过终端使用以下命令安装SBT：

echo "deb https://dl.bintray.com/sbt/debian /" | sudo tee -a /etc/apt/sources.list.d/sbt.list
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2EE0EA64E40A89B84B2DF73499E82A75642AC823
sudo apt-get update
sudo apt-get install sbt

在我的Ubuntu 18.04和java版本上：

openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-8u171-b11-0ubuntu0.18.04.1-b11)
OpenJDK 64-Bit Server VM (build 25.171-b11, mixed mode)

安装成功但是当我尝试通过终端启动SBT时，我已经

https://repo.scala-sbt.org/scalasbt/ivy-snapshots/org.scala-sbt/sbt/1.1.6/ivys/ivy.xml

Answer 1

根本原因是openjdk-11-jdk（在Ubuntu 18.04中是默认的）和sbt包设置之间的冲突。它已经在Debian中修复，很快就会被包含在Ubuntu中。同时，最简单的解决方法是将您的java降级为版本8.使用ca-certificates-java的其他解决方案要复杂得多。

首先删除冲突的包：

sudo apt-get remove --purge openjdk* java-common default-jdk
sudo apt-get remove --purge sbt
sudo apt-get autoremove --purge

通过以下方式检查您成功删除所有相关包裹的天气：

sudo update-alternatives --config java

系统会提示您没有可用于配置的Java ，否则此解决方法将失败。

然后重新安装所需的包：

sudo apt-get install openjdk-8-jdk sbt

测试：

sbt compile

Answer 2

问题是java-certificates所以你需要运行这些命令：

重新安装JDK

$ sudo apt-get purge openjdk-8-jdk java-common
$ sudo apt-get install openjdk-8-jdk

运行sbt

$ sbt

Answer 3

我建议您完全独立于OS软件包安装Java / Scala / SBT。对于开发人员而言apt-get，yum或其他任何东西安装了特定版本的Java并不重要（或无关紧要！）。

从开发人员的角度来看，在多个Java版本下测试您的应用程序甚至是有意义的。我以前见过这种情况：＆＃34;它有效＆＃34;在Java 1.8.x下但是＆＃34;它失败了＃34;在Java 1.8.y。

因此，从开发人员的角度来看，您会对快速切换Java版本感兴趣，以便您可以快速确保它在这几个不同版本下正常工作，无论您的特定版本安装在哪个特定版本上操作系统。

如果您喜欢这个想法，这就是它的工作原理：

手动下载您喜欢的所有JDK版本，并在您的主文件夹下的给定文件夹下解压缩它们，例如：$HOME/tools。我有一个脚本可以自动为您安装某个版本的JDK：https://github.com/frgomes/bash-scripts/blob/master/scripts/user-install/install-java.sh
以virtualenv方式调整环境变量。它比你想象的容易，你甚至不需要virtualenv。您所需要的只是source一个shell脚本，它在登录时运行，定义JAVA_HOME，指向您$HOME/tools下的给定Java版本。这是一个例子：https://github.com/frgomes/bash-scripts/blob/master/bashrc-virtualenvs/j8s12/bin/postactivate
手动安装Scala和SBT版本，或使用https://github.com/frgomes/bash-scripts/blob/master/scripts/user-install/install-scala.sh

Answer 4

这为我修复了它。

sudo update-ca-certificates -f

Answer 5

就我而言，我通过删除.m2，.ivy和.sbt解决了这一问题。下次执行sbt时，它修复了所有问题。

我相信我在使用缓存的依赖项或其他东西时会破坏sbt。

找不到模块：org.scala-sbt＃sbt; 1.1.6

5 个答案:

重新安装JDK

运行sbt
