As Error:Could not determine the class-path for interface com.android.builder.model.AndroidProject.

Error: Error: Could not determine the class – path for interface com. Android. Builder. Model. The AndroidProject.
Reason: The gradle version was low when Eclipse exported the project, so the gradle configuration should be changed
Solution: Duplicate the normal project 2 configuration
1. Modify Build. gradle (gradle version number and Android {… })

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

android {
    compileSdkVersion 26
    buildToolsVersion '26.0.3'
    ......
}

2, the gradle – wrapper. Properties

Error in loadNamespace(name) : there is no package called ‘yaml’

Yaml packages were installed incorrectly, whether I downloaded zip from Cran to install locally, or install.packages(” YAML “) were installed, or displayed

Warning in install.packages :
  package ‘yaml’ is not available (for R version 3.5.3)

Either it shows that
cannot be installed on the search site, and there is finally a work method
1) first type.libpaths (), which will pop up the folder path of the Library where we installed the R package
2) enter this path, remove the original folder of yaml package
3) and restart Rstudio, enter the following code:

install.packages("yaml", dependencies=TRUE, repos='http://cran.rstudio.com/')

Installation successful!!

After looking up online information:
in WEB level application, there will be an unexpected lazy error, the solution is to set lazy= “false”

The icon on the layui page is not displayed, and an error message is reported: Failed to decode downloaded font …..

The solution
This can be resolved by adding the following information to the pom.xml

<build>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
                <excludes>
                    <exclude>**/*.woff</exclude>
                    <exclude>**/*.woff2</exclude>
                    <exclude>**/*.ttf</exclude>
                </excludes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>false</filtering>
                <includes>
                    <include>**/*.woff</include>
                    <include>**/*.woff2</include>
                    <include>**/*.ttf</include>
                </includes>
            </resource>
        </resources>
    </build>

Solve the browser err_proxy_connection_failed problem

clang: error: linker command failed with exit code 1 (use -v to see invocation)

ld: library not found for -lGoogleAdMobAds
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Solutions:
The first:
I have a similar “not found library” problem. However, this is because I accidentally used the . Xcodeproj file instead of the .xcworkspace file. (The blogger USES the first solution)
The second:
Select your target, please "Build Phases" upon "Link Binary With Libraries" delete ". A " this library file
The third:
Set Build Active architecture Only to Yes
The fourth type:
Sometimes you just need to remove the reference to the library and add the reference again.
In addition to adding the Google Mobile AD SDK and other libraries from scratch again, I recommend that you look at the “Library Search Path.” In some cases where you copy or copy a destination, Xcode decides it needs to escape any double quotes “with” \ “. Make sure you delete all of them — it should look like this

Xcode:Task failed with exit 1 signal 0 {

The error message is as follows:
was the problem I encountered while trying to build apps and simulate them on my phone.

Solution: When prompted for a password in the key string, press always Allow, rather than simply allow.
If you are currently in this process, restart your computer, then open Xcode and simulate it on a common device, and you will be prompted to re-enter your password. Make sure that clicking is always allowed.

Edit the file to be edited by gedit. After saving, a warning of Set document metadata failed: Setting attribute metadata::gedit-position no appears

Set document metadata failed: Setting attribute metadata::gedit-position no
My situation is as follows:

About this situation can see: https://askubuntu.com/questions/798935/set-document-metadata-failed-when-i-run-sudo-gedit
The blog’s solution is that it’s just a warning, just ignore it.
