SBT inotify 实例达到用户限制或打开文件过多

Question

我已经克隆了 AWS Code Build REPO。

当我尝试构建时

 => ERROR [runtimes_n_corretto 4/6] RUN sbt version -Dsbt.rootdir=true                                      14.6s

    --------------------

Dockerfile 中的 sbt 行

ENV PATH "/usr/local/bin/sbt/bin:$PATH"
RUN sbt version -Dsbt.rootdir=true

sbt version

显示

[warn] No sbt.version set in project/build.properties, base directory: /home/miki/aws-codebuild-docker-images/ubuntu/standard/5.0
[info] welcome to sbt 1.9.4 (Ubuntu Java 11.0.20)
[info] set current project to root-5-0 (in build file:/home/miki/aws-codebuild-docker-images/ubuntu/standard/5.0/
[info] 0.1.0-SNAPSHOT

如何解决这个问题？

我使用以下方法解决了这个问题：

echo 256 | sudo tee /proc/sys/fs/inotify/max_user_instances
