Intellij not including gradle dependency on classpath when running an app - java

IntelliJ is not including by logback-classic dependency on classpath when running the application from IDE (it is kotlin application, but it shouldn't matter). My gradle build contains a line:
compile group: 'ch.qos.logback', name: 'logback-classic', version: '1.+'
Dependency is correctly listed under "External Libraries" in IntelliJ.
When I try to manually reference a class that the dependency provides in the source code, compiler doesn't complain and it compiles the code successfully.
However, when I run the application I get ClassNotFoundException.
//This import is provided by logback-classic library
import org.slf4j.impl.StaticLoggerBinder
...
// This compiles successfully, but will trigger ClassNotFoundException when run
val singleton = StaticLoggerBinder.getSingleton()
I included the code to list out the runtime classpath:
val cl = ClassLoader.getSystemClassLoader()
val urls = (cl as URLClassLoader).urLs
for (url in urls) {
System.out.println(url.file)
}
And the output, when run from IDE, doesn't include logback-classic. Sample output:

Fascinatingly, logback-core is in there while logback-classic is not (and logback-core is a transitive dependency of logback-classic).
I tried invalidating InteliJ cahces, rebuilding and restarting InteliJ. Compling from gradle and running the jar works fine. Any suggestions?

It seems this a bug in InteliJ for which I'll file a bug report. Including this answer with a workaround here for anyone who might encounter similar issue.
It seems that when there is a certain combinations of dependencies present on the classpath, then when you use gradle dependency like this
compile group: 'ch.qos.logback', name: 'logback-classic', version: '1.+'
it will not get included when run from the IDE. But if you include it like this:
compile group: 'ch.qos.logback', name: 'logback-classic', version: '1.1.+'
then it works. First example did work for a while, until I included more dependencies.

Build failed : Cannot find JAR 'aws-java-sdk-core-1.11.948.jar' SpringBoot

I'm trying to run spring boot project, but i get this error.
any idea what error is this ?
Cannot find JAR 'aws-java-sdk-core-1.11.948.jar' required by module 'gradle-resources-s3' using classpath or distribution directory '/home/mbunderline76/.gradle/wrapper/dists/gradle-7.3.2-bin/4k4cn06q0rruwh9dpndf9gmi8/gradle-7.3.2'
You need to add dependency for the jar required by your gradle version. Trying adding this dependency and refreshing your gradle.
implementation group: 'com.amazonaws', name: 'aws-java-sdk-core', version: '1.11.948'
or
implementation 'com.amazonaws:aws-java-sdk-core:1.11.948'
Running on M1 Mac with Kotlin, Adding
configurations.all {
resolutionStrategy {
force ("software.amazon.awssdk.crt:aws-crt:0.16.12")
}
}
to the build.gradle.kts file (don't forget to refresh) worked for me as a work around per this(https://github.com/awslabs/aws-sdk-kotlin/issues/473) github issue

java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver despite the fact it is in dependencies of gradle.build file

I have read top 10-15 questions with answers by the following query https://stackoverflow.com/search?q=com.microsoft.sqlserver.jdbc.SQLServerDriver%22
However, I still don't understand why it doesn't work.
Usual steps to solve this issue:
Make sure that the jar is add to as a dependecy in your build/dependency management tool (Ant/Maven (pom.xml)/Gradle(gralde.build))
Yes, it is in my case:
dependencies {
compile group: 'com.microsoft.sqlserver', name: 'mssql-jdbc', version: '7.4.0.jre8'
testCompile group: 'com.microsoft.sqlserver', name: 'mssql-jdbc', version: '7.4.0.jre8'
}
in build.gradle file
and gradle build command works without exceptions.
An alternative solution is to download jar file manually from https://learn.microsoft.com/en-us/sql/connect/jdbc/download-microsoft-jdbc-driver-for-sql-server?view=sql-server-ver15
and then add it to a classpath. This solution is undesirable i don't want to do something manually that has to be done by a build tool.
So the question is why I am getting the error "java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver" and I cannot see this jar in the dependencies tab
despite the fact that the jar is mentioned in my build.gradle file in the dependency section as a compile-time dependency and as a Test time dependency :
FYI:
That is how it is called in my code:
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
It looks like IntelliJ hasn't imported the addition of these dependency. This usually means that the auto-import is disabled.
You can reimport your gradle file by clicking the reimport button in the gradle tab of IDEA. You can enable auto-import by clicking the Gradle Settings button in the gradle tab, and enabling "Automatically import this project on changes in build script files".
On a separate not, you don't need to declare testCompile if you also declare a dependency as compile.

IntelliJ with gradle gives inconsistency in compilation

I'm writing Minecraft Plugin using IntelliJ IDEA Ultimate with gradle. I have added dependency org.spigotmc:spigot-api:1.13.2-R0.1-SNAPSHOT as compileOnly. During development, I noticed that gradle compiles my code in different way than IntelliJ does. For example, IntelliJ was unable to accept addPassenger on Boat, but gradle compiled it. In the opposite way, if I changed it into setPassenger, IntelliJ didn't mark it as error, but gradle failed to compile. I tried to invalidate caches, reimport, clean, even remove %userprofile%\.gradle directory, nothing helped. As a POC I changed compileOnly to compile and it worked well, IntelliJ and gradle compilation results were consistent. What's the reason?
Ok, I found the solution (and forgot about this question).
I had been using multiple dependencies, and one load another with older version that I loaded implicitly in my build.gradle. However, they weren't exactly the same dependencies, but parallel ones. So gradle could not choose higher version of one dependency. Solution was to exclude this one explicitly loaded dependency and everything worked well.
Before:
dependencies {
compileOnly 'com.sk89q.worldedit:worldedit-bukkit:7.0.1'
compileOnly group: 'org.spigotmc', name:'spigot-api', version: '1.15.1-R0.1-SNAPSHOT'
}
After:
dependencies {
compileOnly('com.sk89q.worldedit:worldedit-bukkit:7.0.1') {
exclude `org.bukkit:bukkit:1.15.1-R0.1-SNAPSHOT`
}
compileOnly group: 'org.spigotmc', name:'spigot-api', version: '1.15.1-R0.1-SNAPSHOT'
}

Same interface in 2 different dependency issue

I have conflict problem with dependencies.
My project has two dependencies like this:
dependencies {
provided group: 'javax.servlet', name: 'javax.servlet-api', version: '3.1.0'
compile files('path/to/ABC.jar')
}
ABC.jar has its own dependency to javax.servlet:servlet-api:
dependencies {
provided group: 'javax.servlet', name: 'servlet-api', version: '2.5'
}
Here is the problem I am dealing with; I need to use ServletContext interface which is provided by both servlet-api libraries and the compiler uses wrong one.
Gradle auto-resolves version conflicts as described here.
But in my case it doesn't help, because it only works when a dependency has two different versions. In this case; although it's a newer version issue, the name has changed from javax.servlet:servlet-api to javax.servlet:javax.servlet-api. So gradle doesn't auto-resolve this conflict, because it doesn't seem to be a version issue.
The thing I tried was using excluding transitive dependency as described here.
compile files('path/to/ABC.jar') {
exclude group: 'javax.servlet'
}
But it didn't work, it seems exclude doesn't work on local 'jar' files.
Now, I don't know what else to do.
How can I exclude a dependency of a dependency which is added as a local file?
(If the first question doesn't have any answer yet) How can I say to the compiler to use the correct ServletContext interface?
compile files('path/to/ABC.jar') is a file dependency, a file dependency does not have any dependency information, so it does not introduce transitive dependencies. If this ABC.jar is a "fat" jar that has the dependency-classes included in the JAR, it is not suited for usage in something like Gradle, Maven or Ant/Ivy that is supposed to handle the dependencies. You would have to use a proper "thin" version of the dependency with the dependencies properly declared, or you need to "repackage" that JAR in your build script to exclude the dependency classes you don't want to pull in. No dependency management can do this for you.
You can execute gradlew dependencyInsight --configuration runtime --dependency javax.servlet:servlet-api or gradlew dependencies --configuration runtime to find out where the dependency really comes from.
Actually your example should not even compile if I see it correctly, because it should most probably be
compile files('path/to/ABC.jar'), {
exclude group: 'javax.servlet'
}
or
compile(files('path/to/ABC.jar')) {
exclude group: 'javax.servlet'
}
But as I said, with a local file dependency there are no transitive dependencies, so an exclude does not make sense at all anyway.
To make the Gradle version conflict magic work, you can simply tell Gradle that those libraries are actually the same library just with different coordinates by using a module replacement like
dependencies {
modules {
module('javax.servlet:servlet-api') {
replacedBy 'javax.servlet:javax.servlet-api'
}
}
}
Then Gradle sees them as the same library and can do its version conflict resolution magic. Whether the library that needs the old version still works with the new version is a different topic that you have to check and / or try yourself. This like always depends on whether the new version is backwards compatible to the old version.
I have no way to test this now, but I believe your syntax is wrong. I have some examples here that look different, in your case it would be:
compile(files('path/to/ABC.jar')) {
exclude group: 'javax.servlet'
}
As I say, I cannot test it now, check if it helps and give a comment.

Gradle not downloading test dependency

I am looking to add a test dependency to my project which uses gradle. What I simply need is for gradle to download the dependency jar so I can import part of the package. What I need is the following package:
import org.springframework.security.test.*
So I edited my gradle file to contain
dependencies {
compile('org.springframework.boot:spring-boot-starter-data-jpa')
compile('org.springframework.boot:spring-boot-starter-security')
compile('org.springframework.boot:spring-boot-starter-thymeleaf')
runtime('org.hsqldb:hsqldb')
testCompile('org.springframework.boot:spring-boot-starter-test')
testCompile('org.springframework.security:spring-security-test') // This is what I added to try and download the new dependency
}
I tried building the project after entering this. Unfortunately this didn't work and I cannot import org.springframework.security.test.* I then ran gradlew test which actually had some success and showed:
Download https://repo1.maven.org/maven2/org/springframework/security/spring-security-test/4.0.3.RELEASE/spring-security-test-4.0.3.RELEASE.pom
Download https://repo1.maven.org/maven2/org/springframework/security/spring-security-test/4.0.3.RELEASE/spring-security-test-4.0.3.RELEASE.jar
Though I have no idea where it downloaded to. Navigating to $HOME/.gradle/caches/modules-2/files-2.1/org.springframework.security I can see no sign of the downloaded package (and Idea doesn't recognise it in its external libraries). Running gradle build --refresh-dependencies didn't seem to work.
Any help would be very much appreciated.
Closes SO question I could find
I had the same issue, it works if a specific version is included in the dependency, such as:
testCompile group: 'org.springframework.security', name: 'spring-security-test', version: '5.1.6.RELEASE'
