Getting started with Gradle-Grovvy language foundation

Image
  Why learn Grovvy The official recommended language of Gradle is Groovy, which is a jvm language. If you want to perform plug-in modules, hot repairs, complex construction systems, etc., you need a little understanding of Groovy. You don't need to learn the details of Groovvy. Generally, the benefits are too great. Low, like bloggers only use Gradle to build SpringBoot, and the main project language is not Groovy. There are quite a few Gradle users who have no basic concepts at all. Whenever they encounter a need or problem, they need to find it online. This is a misunderstanding. Gradle is not just a configuration script, I personally think that behind it is a combination of two languages: Groovy Language + Gradle DSL The DSL part can also be expanded.

  For projects with multiple Gradle projects, if the main project is executing unit test, other sub-projects will be executed together, and some advanced settings are required. First refer to another article, use eclipse to configure two SpringBoot projects: lab-springboot, library1. Gradle references the level project First, modify the build.gradle of library1 and add these codes at the bottom of the file: configurations { // Gradle DSL // The names of the configurations which this configuration extends from. testOutput.extendsFrom (testImplementation) } task jarTest (type: Jar, dependsOn: testClasses) { from sourceSets.test.output classifier = 'test' // The classifier distinguishes different artifacts build from the same project. } artifacts { testOutput jarTest } Then modify the build.gradle of lab-springboot and add these codes at the bottom of the file. Note that there may be other codes in the dependencies: dependencies { im...

WordPress easy to generate static website plug-in

Image
  Some people use Static CMS to design things like Jekyll and Hexo, but almost none of these things have more user-friendly content editors, such as powerful things like Divi, so there is another trick, which is to edit the website with WordPress. , And then use some static generators to generate static websites. There is a set of the simplest and most effective to try: Simply Static. After installation, select "Save for offline use" in Settings and "Temporary Files Directory" in Advanced settings to set the path to be exported. The permissions of the path must be readable and writable.  Then you can go to Generate and click "Generate Static Files". The set path may not allow you to click URL download directly, you can download it in other ways, or write an automatic sftp transmission to other places. After testing, the plug-in can normally produce the design and layout edited by Divi.
