Windows 10 和 Neo4j 桌面 1.4.9、Java 17。
每次我尝试转储数据库时，都会在 Neo4j Desktop 中收到以下错误。
我检查了 Neo4jDesktop 日志。
[2021-11-21 18:43:55.043] [error] Selecting JVM - Version:11.0.8, Name:OpenJDK 64-Bit Server VM, Vendor:Azul Systems, Inc.
Invalid value for option '--to': cannot convert 'P:\Software\DB\NoSQL\Neo4j_data\relate-data\projects\project-21158abc-7557-4b51-8eb1-19276b14bfda\from-blog-neo4j-Nov-21-2021-18:43:48.dump' to interface java.nio.file.Path (java.nio.file.InvalidPathException: Illegal char <:> at index 128: P:\Software\DB\NoSQL\Neo4j_data\relate-data\projects\project-21158abc-7557-4b51-8eb1-19276b14bfda\from-blog-neo4j-Nov-21-2021-18:43:48.dump)
Dump a database into a single-file archive.
USAGE
neo4j-admin dump [--expand-commands] [--verbose] [--database=<database>]
--to=<path>
DESCRIPTION
Dump a database into a single-file archive. The archive can be used by the load
command. <destination-path> can be a file or directory (in which case a file
called <database>.dump will be created). It is not possible to dump a database
that is mounted in a running Neo4j server.
OPTIONS
--verbose Enable verbose output.
--expand-commands Allow command expansion in config value evaluation.
--database=<database>
Name of the database to dump.
Default: neo4j
--to=<path> Destination (file or folder) of database dump.
当我尝试来自 Powershell 的命令时，它给出了有关 JVM 版本的错误，并要求更改 JDK：

**************降级到Java 11 降级后（只是将环境变量指向jdk 11），neo4j-admin转储命令有效，但Neo4j桌面仍然无法转储，错误在日志中是相同的。
