RAD Studio 10.4 is the biggest improvement to Delphi code tools in years, a major improvement to Delphi Code Insight, which provides Code Insight using a Language Server Protocol (LSP) implementation.
10.4 greatly improves developer productivity when working on large projects with millions of lines of code.
How to Close LSP
Options – User Interface – Editor – Language – Code Insight – Code Insight Manager. The default is LSP, change to Classic.
When I packaged the project, I reported an error:
Failure to find com.st:oscarJDBC16:pom:1.0.0 in http://maven.aliyun.com/nexus/content/groups/public/ was cached in the local repository, resolution will not be reattempted until the update interval of public has elapsed or updates are forced
In order to solve this problem, a lot of information was consulted as follows:
1,
Go to your own .m2 folder and delete all the xxx.lastUpdated files, run maven again, ok!
Or add the -U parameter when using maven, you can ignore xxx.lastUpdated..
Here, a simple investigation is not caused by this reason
2,
Change the version, or change the source to try
I’ve changed it several times, but it still gives an error
3,
Added updatePolicy property to release or snapshots version of repository, where updatePolicy can be set to “always”, “daily” (default), “interval:XXX” (minutes) or “never”
<repositories>
<repository>
<id>io.spring.repo.maven.release</id>
<url>http://repo.spring.io/release/</url>
<releases>
<enabled>true</enabled>
<updatePolicy>always</updatePolicy>
</releases>
<snapshots><enabled>false</enabled></snapshots>
</repository>
</repositories>
still error
final solution

Problem: One customer is asking why he cannot open Auto ECU Programmer V2.25 KTAG red PCB software on CD. And it gives a warning “Program already running”. What the reason, any suggestions?
solution ktag red pcb program already running issue – Solution: KTAG Red PCB “Program already running” Issue – KTAG Red PCB Program already running

Yellow warning when using stringRedisTemplate.hasKey(**)
Warning message: IDEA Unboxing of ‘stringRedisTemplate.hasKey(xx)’ may produce ‘NullPointerException’ warning
Possible null pointer exception when unboxing
Look through the hasKey source code
Looking at the hasKey source code, the hasKey method returns an object wrapper, but using it inside the if condition implicitly unboxes it (ie, converts the result of the call to the original value). If for some reason the hasKey method might return null, an error will occur. For security, you can check if the key exists by following the steps below
solution:
if ( Boolean.TRUE.equals ( redisTemplate.hasKey ( XXXX)) { }

Error while reading file. This is an encoding problem that python is very prone to encounter when reading files. The solution is to add encoding=’ISO-8859-1′.
Since the default ftp download is ascii mode, the downloaded file encoding is iso8859-1.
maven import error
Cannot resolve org.springframework.boot:spring-boot-autoconfigure:2.6.2
Solution 1:
Delete the package corresponding to the local maven and download it again
Solution 2:
It may be a springboot version problem, lower the version (2.6.2 can’t be used before. Just change to 2.5.7)

<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version> 2.5.7 </version>
