下载 gradle 依赖项时出现 Java Spring Boot 项目错误

Question

One of my coworkers recently deleted his ".gradle" directory. He was not able to build the project again, because of the following error:

Caused by: org.gradle.api.resources.ResourceException: Could not get resource 'https://repo.spring.io/plugins-release/com/github/node-gradle/gradle-node-plugin/2.2.1/gradle-node-plugin-2.2.1.pom'.

And I tried to access the URL 'https://repo.spring.io/plugins-release/com/github/node-gradle/gradle-node-plugin/2.2.1/gradle-node-plugin-2.2.1.pom' directly on browser, and it's now asking user and password.

Did somewone known what's happening? Did this repo was moved to another host?

Thanks in advance.

edit: My gradle repositories:

repositories {
        mavenLocal()
        mavenCentral()
        jcenter()
        maven { url "https://repo.spring.io/plugins-release" }
        maven { url "https://plugins.gradle.org/m2/" }
        
    }

Answer 1

Looks like you are downloading from a jfrog repository and are missing the gradle.properties file .. The .gradle folder contains a file called "gradle.properties" which contains the credentials (usually encrypted from the above repo in case of employer controlled repo)to access the jars/poms.

The steps to generate and download : 1.Go to https://repo.spring.io/ and login if you have workplace credentials for accessing the repo. 2.search for "plugins-release" is the "set-me-up" scroller. 3. select Gradle in "tools" drop-down and Generate gradle.properties. 4.download this "gradle.properties" and put it in .gradle folder under the username directory.

Answer 2

switch the order of the last 2 lines under repositories . It becomes:

repositories {
        mavenLocal()
        mavenCentral()
        jcenter()
        maven { url "https://plugins.gradle.org/m2/" }
        maven { url "https://repo.spring.io/plugins-release" }
    }

This way Gradle will resolve gradle-node-plugin from the official Gradle plugin portal ( https://plugins.gradle.org/m2/ ), instead of from Spring's Artifactory (which caches 3rd party artifacts, but you don't really want to fetch non Spring plugins from it).

PS:
I am assuming that in your build.gradle you apply the plugin "com.moowork.node" as shown here under "Using legacy plugin application", and that the repositories block is inside a buildscript block. Otherwise, your repositories block has no effect on plugin resolution.
