无法让 sbt-plugin 和 sbt-play-ebean 与 Play 2.8.0 和 sbt 1.5.5 一起使用答案

【问题标题】：Cannot get sbt-plugin nor sbt-play-ebean to work with Play 2.8.0 and sbt 1.5.5无法让 sbt-plugin 和 sbt-play-ebean 与 Play 2.8.0 和 sbt 1.5.5 一起使用
【发布时间】：2021-10-04 16:04:27
【问题描述】：

在中断三年后重新回到 Play 框架，并尝试从最新的 Play (2.8.0) 和 sbt (1.5.5) 开始。

我正在尝试运行一个项目并收到此消息：

[info] welcome to sbt 1.5.5 (Oracle Corporation Java 1.8.0_41)
[info] loading settings for project global-plugins from plugins.sbt ...
[info] loading global plugins from C:\Users\dzell\.sbt\1.0\plugins

[warn]  Note: Unresolved dependencies path:
[error] sbt.librarymanagement.ResolveException: Error downloading com.typesafe.play:sbt-plugin;sbtVersion=1.0;scalaVersion=2.12:2.8.0

在我的plugins.sbt 文件中，我有：

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.8.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "4.0.6")
addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "5.2.4")

在我的build.sbt 文件中，我有：

scalaVersion := "2.13.6"

跑步：

C:\Users\dzell>java -version
java version "1.8.0_301"
Java(TM) SE Runtime Environment (build 1.8.0_301-b09)
Java HotSpot(TM) Client VM (build 25.301-b09, mixed mode, sharing)

C:\Users\dzell>javac -version
javac 1.8.0_41

我猜是版本冲突，但不知道如何解决。我找到了其他帖子，但他们没有给我答案： Unresolved Dependencies sbt with play framework

Play! Framework and SBT - Problems with ebeans module

SBT. Resolving dependencies for play sbt-plugin

Unresolved dependency sbt-play-ebean

sbt can not find the ebean dependency (Some unresolved dependencies have extra attributes)

How to add Play Ebean in Play project?

我应该只使用错误消息中所说的 sbt 1.0 和 scala 2.12 吗？

感谢您的帮助 - 期待重返 Play。

------------------ 2021 年 8 月 2 日编辑 - 专注于 ivy.xml：

到目前为止，我有 .ivy2 文件夹，但该文件夹内没有文件夹 - 只有一个名为 .sbt.ivy.lock 的文件。我从上面的错误中尝试了这个 URL，它让我下载了一个文件： https://repo.scala-sbt.org/scalasbt/sbt-plugin-releases/com.typesafe.play/sbt-plugin/scala_2.12/sbt_1.0/2.8.0/ivys/ivy.xml

我尝试手动创建错误中列出的文件夹结构：

C:\Users\dzell\.ivy2\localcom.typesafe.play\sbt-plugin\scala_2.12\sbt_1.0\2.8.0\ivys\ivy.xml

我将下载的文件放在上面那个文件夹中，但没有修复错误。

【问题讨论】：

SBT 1.0 和 Scala 2.12 版本信息仅适用于插件（始终在这些版本中），您不需要更改项目的版本。
感谢您的回复！我的问题是当我试图让应用程序运行时如何摆脱错误？我在上面的帖子中添加了完整的错误以供参考。谢谢！
主要错误是 InvalidAlgorithmParameterException: trustAnchors 参数必须为非空 但这对我来说并没有响起任何警钟。
这能回答你的问题吗？ Could not transfer artifact from/to central because of InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
我现在知道发生了什么，但是，我不知道该把它放在哪里 -- -Djavax.net.ssl.trustStore=/usr/java/jdk1.8.0_91/jre/lib/security/cacerts -- 这是否放在 build.sbt 中（我知道我必须将路径更改为我的文件夹结构）？另外，路径和文件——C:\Users\dzell\.ivy2\localcom.typesafe.play\sbt-plugin\scala_2.12\sbt_1.0\2.8.0\ivys\ivy.xml——都不存在，我只有C:\Users\dzell\.ivy2文件夹——感谢帮助！

标签： java playframework sbt

【解决方案1】：

查看Java/JRE/JDK 安装后，我注意到没有cacerts 文件。我卸载了 Java/JRE/JDK - 确保删除了所有引用/文件夹/文件。

我创建了一个 Oracle 帐户来从 Oracle 的站点下载安装文件，因为 OpenJDK 给我带来了问题。

我首先下载并安装了 Java/JRE 文件jre-8u301-windows-x64.exe。我确保在命令提示符下使用java -version 安装了Java。我很高兴。

然后我下载并安装了 JDK 文件jdk-8u301-windows-x64.exe。我确保在命令提示符下使用javac -version 安装了Java。我很高兴。

我启动了 sbt 并且没有任何问题 - 它已修复。
