"Project cannot be built until its prerequisite is built" errors each time I close & open VSCode

I have a multi-module Maven project that I created using Eclipse, and now I am trying to migrate to VSCode.

I have opened the project in VSCode, and it has updated all .project and .classpath files. There is no error in the project, and everything seems to work perfectly.
But after I close VSCode and open it again, without having changed a single line, after Java builds everything, suddenly most of the modules are in red, and I see this type of error in the Problems tab:

"The project cannot be built until its prerequisite XXX is built. Cleaning and building all projects is recommended"

If I "Clean Java Language Server Workspace", the problems disappear, until I close+open VSCode again.
If I "Force Java Compilation > Full", the same. Problems disappear until the next restart.

I guess this shouldn't happen, but I don't know if it is a problem in my project (as I've said, everything works until I close the workspace), I have something configured incorrectly or it is a bug in vscode-java (and if so, if there's any workaround).

I am using JDK 8.

I have tried the pre-release version too, but I get the same problems.

Thank you in advance, please let me know if you need more info.

まず、VSCodeを再度開いた後にマルチモジュール Maven プロジェクトで失敗を再現し、Java ビルドの前後で .project ファイルと .classpath ファイルを比較します。Java Language Server Workspace をクリーンアップするか、Force Java Compilation > Full を使用すると結果が変わるかを確認します。再起動に関連する原因、または前提条件のエラーに対する信頼できる回避策を特定できれば完了です。
