I have a Gradle project in IntelliJ.
I added this dependency to Maven dependencies list
<dependency>
<groupId>org.imgscalr</groupId>
<artifactId>imgscalr-lib</artifactId>
<version>4.2</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
When I try to compile my code using gradlew build I receive this compilation error:
gradlew build
:compileJava
....java:5: error: package org.imgscalr does not exist
import org.imgscalr.Scalr;
^
....java:52: error: cannot find symbol
BufferedImage thumbnail = Scalr.resize(image, 150);
^
symbol: variable Scalr
location: class PlaceController

What is happening?
After adding the dependency inside maven file, IntelliJ automatically downloads the file and imports it where it is needed. By doing this, the error from the IDE, that says tahat Scalr could not be found, dissapears.
You should be covering this in your build.gradle file instead. Here's an example of how it would look.
repositories {
mavenCentral()
}
dependencies {
compile 'org.imgscalr:imgscalr-lib:4.2'
}
If you were looking to do a wholesale conversion from Maven to Gradle, you'd have to convert your POMs over first and iron out any bugs that may have resulted due to the conversion.

i've just tried using a webassambly in java.
I wanted to use wasmerio to achieve this but following the instructions at https://github.com/wasmerio/wasmer-java (The github page of wasmerio)
I ended up with an exception after running gradle build:
gradle build

Searched in the following locations:

If the artifact you are trying to retrieve can be found in the repository but without metadata in 'Maven POM' format, you need to adjust the 'metadataSources { ... }' of the repository declaration.

My gradle build file look like the following:
plugins {
id 'java'
}
group 'org.example'
version '1.0-SNAPSHOT'
repositories {
mavenCentral()
}
dependencies {
testImplementation 'org.junit.jupiter:junit-jupiter-api:5.7.0'

implementation "org.wasmer:wasmer-jni-amd64-linux:0.2.0"
}
test {

Any Ideas?
Thanks in advance

I am encountering such an error in my application sale. I couldn't find anything exactly as a solution.

As #Narendra_Nath said, it is because of the bintray dependencies and Jcenter shutting down.
you can refer to this article https://blog.gradle.org/jcenter-shutdown
the solution that worked for me is changing the repositories in the (Top-level build.gradle) to
buildscript {
repositories {
google()
mavenCentral()
maven {
url "https://repo.spring.io/release"
}
maven {
url "https://repository.jboss.org/maven2"
} }
You need to declare your dependency correctly "androidx.core:core-ktx:$core_version"
This is because bintray support is now no longer there.
Go to your project level build.gradle and comment out the
bintray dependencies in the allprojects and repositories section
Bintray Shutdown
I am making a program that requires a Gradle dependency, and I am using eclipse. It was working yesterday, and I didn't change anything, but when I restarted my computer it stopped working. This is my first time using Gradle.
I tried refreshing Gradle and restarting eclipse, but it still doesn't see the dependency. I tried changing the distribution url of Gradle in the gradle-wrapper.properties file, and copying everything from one project to another but nothing has worked so far.
this is the content of my build.gradle file
plugins {
// Apply the java-library plugin to add support for Java Library
id 'java-library'
apply plugin: "eclipse"
}
repositories {
maven {
url "https://dl.bintray.com/emilybjoerk/lisoft"
}
}
dependencies {
// This dependency is exported to consumers, that is to say found on their compile classpath.
api 'org.apache.commons:commons-math3:3.6.1'
// this is the dependency I am trying to get to work.
compile 'org.li-soft.gonector:gonector:1.0.0'
// This dependency is used internally, and not exposed to consumers on their own compile classpath.
implementation 'com.google.guava:guava:27.0.1-jre'
// Use JUnit test framework
testImplementation 'junit:junit:4.12'
}
This is the error message:

What am i doing wrong?
EDIT: a typo
If you are using a Bnd workspace model build, then you must configure the build path through each project's bnd.bnd file using the -buildpath Bnd instruction. Then the Bnd gradle plugin will use that information to program the configurations for java compilation.
Your example shows setting a compile dependency for the root gradle project which is wrong since (1) you should be using -buildpath in the project's bnd.bnd file and (2) it is done in the root project which is not meaningful to any child projects like your com.feddericokz.helloworld project.
So change your build.gradle file to not apply the 'java' plugin to the root project and not set compile dependencies for the root project and change your Bnd workspace so that the workspace (cnf) has configured repositories to access the desired bundles, for example https://github.com/osgi/enroute.workspace/blob/4070ff6668a1ee79b9b01cfa4caab86869247e7b/cnf/ext/enroute.bnd#L22-L28, and then set each project's bnd.bnd file to have the desired bundles on the -buildpath.
It is unclear if bnd_version is defined in this line:
classpath "biz.aQute.bnd:biz.aQute.bnd.gradle:${bnd_version}"
Consider adding a gradle.properties file with:
bnd_version=3.5.0
(or whatever version is apporpriate). As best as I can reproduce your situation, my example works for me with this.
Trying to build my project with gradle 2.13.

Try applying the idea plugin to the root plugin. I'm not exactly sure what's going on, but that should solve the issue.
