Xcode13. 2 the first project created is set. The minimum version of IOS is 15.2, which has been compiled several times. The minimum IOS version of the switching project is IOS 10.0 After 0, the following errors appear:
error: Command MergeSwiftModule failed with a nonzero exit code
Solution:
Method 1: clean (Command + Shift + k)
Method 2: Change (Project -> target -> builfsetting -> compilation mode -> debug -> switch to whole module) (but this may slow down subsequent compilation)
Htmlemail uses QQ corporate email to send problem summary
After the local mail sending test is passed according to the parameter information on htmlemail, deploy the service on the ECs to test the mail sending. The first error is reported:
Sending the email to the following server failed : smtp.exmail.qq.com:25
Ping smtp.com directly on the ECS exmail. qq. COM domain name found that the external network on the server is not connected. After opening the external network permission, the above error still exists.
browse the document and try to switch smtpport to port 465:
HtmlEmail.setSmtpPort(465);
Error still reported:
Sending the email to the following server failed : smtp.exmail.qq.com:465
Could not connect SMTP host：smtp.exmail.qq.com, port 465, response: -1
It is found that sslonconnect needs to be set to true when switching to port 465
HtmlEmail.setSSLOnConnect(true);
After modification, the error information is changed to:
Invalid address
Finally, switch smtpport to 587:
HtmlEmail.setSmtpPort(587);
Finally, no error is reported. Record it for review later.
Adding a dependent library is an error when running, because the current project version is lower than the minimum trial version of the third-party dependent library
1. As shown in the current project’s build.gradle without setting the buildToolsVersion.
2. Set minSdkVersion to the minimum version of the dependency library in the current project’s build.gradle as shown here.
Solution:
Check always update snapshots in idea and rebuild Maven project
Failed to transform file ‘xxx’ to match attributes when opening previous projects.
I opened the previous project and encountered a Failed to transform file ‘xxx’ to match attributes error.
There is a problem with the added dependency cache
Solution:
C:\Users\Administrator\.gradle\caches\modules-2\files-2.1 directory, find the conflicting files, delete them, and recompile
Supplement:
If an error is reported:
Null extracted folder for artifact: ResolvedArtifact(componentIdentifier=cn.jiguang.sdk:janalytics:2.0.0, variantName=null, artifactFile=C:\Users\dell\.gradle\caches\modules-2\files-2.1\cn.jiguang.sdk\janalytics\2.0.0\4abdfc462a6164fa5629301f8682a8adb7d3d332\janalytics-2.0.0.aar, extractedFolder=null, dependencyType=ANDROID, isWrappedModule=false, buildMapping={__current_build__=D:\Android\project\build\。。}, mavenCoordinatesCache=com.android.build.gradle.internal.ide.dependencies.MavenCoordinatesCacheBuildService$Inject@5859a341)
This error is also caused by file conflicts
1. Introduction
For the new computer, WSL has installed Ubuntu. When entering Ubuntu, an error occurs
WslRegisterDistribution failed with error: 0x800701bc
2. Solution
This is because the wsl2 kernel is not updated
Enter the administrator permission command line, WSL — update
wsl --update
Checking for updates...
Downloading updates...
Installing the update...
This change will take effect the next time WSL is fully rebooted. To force a reboot, run "wsl --shutdown".
Kernel version: 5.10.60.1Then force restart
wsl --shutdownRunning error

APPLICATION FAILED TO START

Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.springframework.scheduling.quartz.SchedulerAccessor.registerListeners(SchedulerAccessor.java:351)
The following method did not exist:
org.quartz.Scheduler.getListenerManager()Lorg/quartz/ListenerManager;
The method's class, org.quartz.Scheduler, is available from the following locations:
jar:file:/D:/repository/org/opensymphony/quartz/quartz/1.6.1/quartz-1.6.1.jar!/org/quartz/Scheduler.class
It was loaded from the following location:
file:/D:/repository/org/opensymphony/quartz/quartz/1.6.1/quartz-1.6.1.jar
Action:
Correct the classpath of your application so that it contains a single, compatible version of org.quartz.Scheduler
Analysis: it worked well before, but suddenly it didn’t work. Reading the report incorrectly may be caused by the jar package conflict of the scheduled task
1. A global check reveals that shiro-all has introduced this jar package
Solution:
When querying the dependency, I found that it is an optional part of shiro, so I exclude it directly.
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-all</artifactId>
<version>1.4.0</version>
<exclusions>
<exclusion>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-quartz</artifactId>
</exclusion>
</exclusions>
</dependency>If the shiro-all package is introduced in a jar package, the following code can be placed under the parent package introduced by the project
<exclusions>
<exclusion>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-quartz</artifactId>
</exclusion>
</exclusions>
Just follow the steps in the image.

Cause of problem
[indices:admin/create]]; nested: IllegalArgumentException[Validation Failed: 1: this action would add [6] total shards, but this cluster currently has [2998]/[3000] maximum shards open;];
For elasticsearch7 and above, only 3000 shards are allowed by default, which is caused by the insufficient number of available shards in the cluster.
Solution:

E: The repository 'https://download.sublimetext.com apt/stable/ Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
The reason is that a software package called “ca-certificates” is not installed. After installation, you can execute the installation instruction of sublime from the beginning.
@ubuntu:~$ sudo apt install ca-certificatesApplication installation failure: the installation failure is due to the conflict of Providers (generally speaking, the same program has been installed before, with conflict)
Four places need to be modified
(There may be some places that do not have to be modified, but it is still recommended to modify together)
1. There are three places to modify in AndroidManifest.xml
Modify package name
After modifying the package name, you should also modify it
to the same as above
There is a modification of the word: authorities
2. In build.gradle(:app)
Applicationid modify the same
as the package name, and then Sync Now
