Error Message: 2022-03-22 15:55:57,000 (lifecycleSupervisor-1-0) [ERROR – org.apache.flume.source.taildir.ReliableTaildirEventReader.loadPositionFile(ReliableTaildirEventReader.java:147)] Failed loading positionFile: /opt/module/flume/taildir_position.json

use flume1.9 tildir source, memory channel, hdfs sink to write a configuration file, use in hdfs no file into, and then I look at the log file, found the above error

Execution failed for task ‘:app:kaptDebugKotlin‘ [How to Solve]

Error compiling project with kotlin:

Execution failed for task ‘:app:kaptDebugKotlin’.
A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution
java.lang.reflect.InvocationTargetException (no error message)
various kotlin annotation errors will be reported

The problem is that the version of kotlin plug-in is inconsistent with that in build

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        google()
        jcenter()
        
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.3'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

Check the version of the org.jetbrains.kotlin:kotlin-gradle-plugin is consistent with the version of the kotlin that the module depends on or not.

This means that the installation of the Chrome fonts failed, so far found that this has any effect on the use of webrtc later, you can add -no-chromeos-fonts after the command as prompted, meaning not to install the fonts.

ST-LINK Download Program Error: flash download failed – ‘cortex m4‘

Possible cause: Project testing using ST-link download program debugging, before all good to download the program, after some tests such as power-down storage may make the chip locked up
Tried solutions: I have looked for some solutions, but most of them are not add in the programming algorithm of flash download in debug, but they don’t seem to work for me.
Final solution: Download the STM32 ST-LINK Utility software to handle the problem.

1. Connect the board to the computer using ST-LINK and open the STM32 ST-LINK Utility.

2. Click Option Bytes in Target
You don’t need to click connect in Target here, just click Option Bytes directly after opening the software, otherwise mine will prompt a can’t read memory error.
3. Change this to disable, and click apply.

4. After that, you can download the program normally in keil5.

Springboot Compile Error: Execution failed for task ‘:buildSrc:checkFormatMain‘

Solution: Comment out the javaformat in the build.gradle file under buildSrc

[Solved] no identity found – Command CodeSign failed with a nonzero exit code

And repeated re operation without results; Clear the cache, re-enter Xcode, open the project and run without results;

Solution: in Xcode, set the version to be consistent with the tested equipment system version in the project settings.

2. Solution
1.Check whether nacos is open
2.Check whether nacos is open properly
3. nacos and eureka are not the same, eureka is part of the project, nacos is more like a partner relationship.

4. If Nacos starts normally, restart the project, or not

(1) Check annotation @enablediscoveryclient

(2) Check configuration file

# Note the space position
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848 # nacos server location

[Solved] Job for mysqld.service failed because the control process exited with error code.

Install mysql8 in centos8 environment by using yum. The following error messages are reported:

Job for mysqld.service failed because the control process exited with error code.

See "systemctl status mysqld.service" and "journalctl -xe" for details.

Because VIM/etc/my.cnf file Is configured before installation, specifying the directory /var/log/mysqld.log

The actual log directory is /var/log/MySQL/mysqld.log

After modifying the directory, restart OK

Android studio configurate intent-filter and compile error [Solved]

The error contents are as follows:

Manifest merger failed : android:exported needs to be explicitly specified for <activity>. Apps targeting Android 12 and higher are required to specify an explicit value for `android:exported` when the corresponding component has an intent filter defined.

When targeting is greater than or equal to Android 12, if some activities are configured with intent-filter, the exported property must be configured at the same time.

According to the error report, there are two solutions:

1. Modify the targetSdk of build.gradle less than 30.

2. Or add the export attribute to the <Intent-filter> tag in AndroidManifest.xml and assign it to true

Last hammer

No problem!

npm install npm ERR code ERESOLVE [How to Solve]
