Using Jenkins to compile APK Error [How to Solve]

In the past, the project could be built on Jenkins normally. Today, it is suddenly found that the construction is wrong. The problems are as follows:

Could not determine the dependencies of task ':lint'.
> Could not resolve all artifacts for configuration ':releaseUnitTestCompileClasspath'.
   > Could not resolve junit:junit:4.+.
     Required by:
         project :
      > Failed to list versions for junit:junit.
         > Unable to load Maven meta-data from http://jcenter.bintray.com/junit/junit/maven-metadata.xml.
            > Could not get resource 'http://jcenter.bintray.com/junit/junit/maven-metadata.xml'.
               > Could not GET 'https://jcenter.bintray.com/junit/junit/maven-metadata.xml'.
                  > org.apache.http.client.ClientProtocolException (no error message)
      > Skipped due to earlier error

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Gradle plug-in version 4.1.2, gradle version 6.5

The solution to this problem is as follows:

1. Find the build.gralle file of moudle.

Modify testImplementation 'junit:junit:4.+' to testImplementation 'junit:junit:4.12'

2. Find the following places in the gradle compilation file used by Jenkins server and modify it to the following information

allprojects {
    repositories {
        jcenter { url "http://jcenter.bintray.com/"}
        google()
        maven { url 'http://repo1.maven.org/maven2' }
    }
}

Then use Jenkins to build again, and the APK can be built normally.

Failed to configure a DataSource: ‘url‘ attribute is not specified and no embedded datasource could [Solved]

Failed to configure a DataSource: ‘url’ attribute is not specified and no embedded datasource could be configured.
Error Messages:

***************************
APPLICATION FAILED TO START
***************************

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
	If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
	If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

 

Solution:

You need to add a configuration in your project’s POM file

<build>
	<resources>
        <!-- Resolving mapper binding exceptions -->
        <resource>
            <directory>src/main/java</directory>

IDEA Create Web Project with maven Error: The desired archetype does not exista…

When I use idea to create a simple web project, there are no SRC, webapp files and so on under the project. And the following errors are reported:

The desired archetype does not exista (org.apache. maven archetypes :maven- archetype webapp:RELEASE)

The specific errors are as follows:

[WARNING] The metadata D:\apache-maven-3.6.1\maven-repository\org\apache\maven\archetypes\maven-archetype-webapp\maven-metadata-alimaven.xml is invalid: entity reference name can not contain character ='

 

Solution:

1. Find the error path (such as the path indicated in bold and underlined above) through the error information above, and find the maven-archetype-webapp folder in your local warehouse

2. Delete files other than folders (such as XML files), and only keep version folders (such as 4.1 folder, 3.1 folder, etc.)

3. Reload the project (or rebuild the project).

[Solved] Error:(3, 46) java: Program Package org.springframework.context.annotation does not exist

This bug should only appear in idea2020
Error:(3, 46) java: Program Package org.springframework.context.annotation does not exist

First, open the file in the upper left corner of the idea, and then click settings

Then click build, execution, deployment > Build Tools > Maven > Runner
check delegate ide build/run actions to Maven

The problem will be solved easily
in addition, warm tips: only idea2020 will have this error, and there are many hidden bugs in 2020. It is recommended to upgrade to idea2021 as soon as possible

How to Solve Assert error (IDEA Package Imported)

When using the MyBatis-Plus starter project, we found that no matter which package under IDEA is imported, Assert will report an error, indicating that the suitable package is not downloaded from maven, and then we have to go to the maven repository ourselves to download the required package Junit.

Open the maven repository, https://mvnrepository.com/, and search for junit will appear many, I will generally choose the number of people using.



thymeleaf Error: An error happened during template parsing Cannot render error page for request

By looking at the front-end html code, there is a syntax error
Although I have commented out the error code
but the use of <! –> can only keep the browser from displaying it, but it can’t keep the thymeleaf template engine from parsing it.
I should have used the thymeleaf comment syntax <! –/* */–> to comment it out

The error message is as follows.
