`sbt dist` 静默退出而不产生二进制文件

Question

我以前可以调用sbt dist 将我的游戏应用程序打包成二进制文件，但是（在进行了很多更改之后）当我尝试它时，它只是默默地存在，没有给出任何错误或生成二进制文件。这是使用-verbose 和-d（调试）运行时的完整输出：

$ sbt dist
[addSbt] arg = '-debug'
[residual] arg = '-sbt-create'
[residual] arg = 'dist'
[residual] arg = '-XX:MaxPermSize=50G'
[residual] arg = '-Xmx50G'
[residual] arg = 'dist'
[process_args] java_version = '14'
[sbt_options] declare -a sbt_options=()
[addMemory] arg = '1024'
[addJava] arg = '-Xms1024m'
[addJava] arg = '-Xmx1024m'
[addJava] arg = '-Xss4M'
[addJava] arg = '-XX:ReservedCodeCacheSize=128m'
[copyRt] java9_rt = '/home/ali/.sbt/0.13/java9-rt-ext-adoptopenjdk_14_0_1/rt.jar'
[addJava] arg = '-Dscala.ext.dirs=/home/ali/.sbt/0.13/java9-rt-ext-adoptopenjdk_14_0_1'

然后它就存在了，我回到了 shell，并且没有生成二进制文件。相比之下，我以前经常看到像inflating xxx.yyy.zzz 这样的消息。

当我运行 sbt clean compile 时会发生同样的事情：

[debug] Full compilation, no sources in previous analysis.
[debug] Copy resource mappings: 
[debug] 
[debug] Other repositories:
[debug] Default repositories:
[debug] Using inline dependencies specified in Scala.

然后又退出了，没有报错。

我怎样才能让 sbt 显示某种错误，表明它为什么不生成二进制文件？

使用：

scalaVersion := "2.13.2"
sbt.version=1.3.12

并播放 2.8.2

从我的 .sbtopts 文件中删除这两行修复了问题：-XX:MaxPermSize=50G 和 -Xmx50G
