Seems in the Springboot version 2.3.x , they have removed the src/test/resources folder ,
I downloaded a skeleton from start.spring.io and did not see it , the current project structure is as below , in such a case how do I use a test specific property file , problem is even if I create a src/test/resources folder and put a test.property file in it , its not being found while I am running the test , Any help is greatly appreciated.
Options I chose while generating the skeleton project in start.spring.io
After a fair amount of research I found my answer , so the "resources" folder under src/test has been removed as part of the skeleton project that we could download from start.spring.io , but now they have included a new build task , well my project is in gradle but I am sure such is the case with Maven too , the name of this task in gradle is "processTestResources" , it copies whatever you have inside your src/test/resources folder to the <Project_HOME>/build/resources/test , which is in the classpath and you can access your resources as you could earlier , the only things is now you have to manually create the "resources" folder , now issue resolved , Thanks everyone for your inputs.
What IDE are you using ? Does the project use Maven ? In Eclipse with Maven if you right click on src/test and choose New -> Source Folder, and call it resources it should be created and added to the test classpath by Maven.
After placing the appropriate files in src/main/resources, and src/test/resources and running
try(final Stream<String> fileStreamFromClasspath = Files.lines(Path.of(ClassLoader.getSystemResource("test.file").toURI())))
{
fileStreamFromClasspath.forEach(l -> System.out.println(l)); // NOSONAR
}
try(final Stream<String> fileStreamFromFilesystem = Files.lines(Path.of(("src/main/resources/test.file"))))
{
fileStreamFromFilesystem.forEach(l -> System.out.println(l)); // NOSONAR
}
try(final Stream<String> testFileStreamFromFilesystem = Files.lines(Path.of(("src/test/resources/test.file"))))
{
testFileStreamFromFilesystem.forEach(l -> System.out.println(l)); // NOSONAR
}
Produces output:
This is the test test file.
This is the main test file.
This is the test test file.

Is it possible to add another resources folder in test folder, which will also be on the classpath?
I need it because I don't want to add application-test.properties file in default resources folder because it belongs in test folder.
I tried to add folder manually but it does not work.
I soloved this problem, in Intellij IDEA by:
Right clicking on the project -> Projectu structure,
and I marked newlycreated folder as Resources file.
It is gradle project or maven? If you have gradle just add the line below to the build.gradle file:
ext {
resourcesDir = projectDir.path + "/other/resources"
}
where the /other/resources is your dedicated resource folder
I'm using intellij (2019.1.1) for a java gradle (5.4.1) project and use lombok (1.18.6) for autogenerating code. Intellij puts generated sources under out/production/classes/generated/... and gradle puts them under build/generated/sources/...
This is fine, and I like that intellij keeps it's own build artifacts separate from gradles, however, intellij seems to look in both directories when running projects and it complains about the duplicate generated classes.
What is the best practice for using intellij with gradle and autogenerated sources? Do you:
tell intellij to output to the same directory as gradle (this
could lead to odd behaviour if a process outside of intellij updates
a file under build/)
tell intellij to perform all tasks with
gradle (i hear this is slower than intellij's make)
tell intellij
to simply ignore the 'build' directory (how do you even do this? and
why does intellij even care about 'build/' when it knows it outputs
to 'out/')
UPDATE: to clarify the situation, the issue is NOT with lombok autogenerated code, it is with hibernate-jpamodelgen. The problem remains the same (duplicate generated sources) but I want to clarify the it is the sources generated by jpamodelgen and not lombok.
UPDATE 2: I have tried the following configuration in an attempt to tell intellij where the generated sources live and also to tell intellij to ignore the build directory. Sadly, this did not work (still get duplicate class error on the generated source files).
apply plugin: 'idea'
idea {
module {
sourceDirs += file('out/production/classes/generated')
generatedSourceDirs += file('out/production/classes/generated')
excludeDirs += file('build')
}
}
UPDATE 3:
Tried the advice from M.Riccuiti and deleted build/, out/, .idea/, .gradle/ and reimported the gradle project but intellij is still seeing the generated sources in the build/ directory.
Here is an approach that finally worked for me. The trick is to notice that when gradle generates the classes, it puts them in:
build\generated\sources\annotationProcessor\java\main\com...
but intellij has the production sources directory set to "generated" in this case, the sources go to:
build\generated\sources\annotationProcessor\java\main\generated\com...
if you compile with gradle first and then use idea, you get both of them, which causes the problem!
To solve this, replace "generated" and "generated_test" in the intellij annotation processors "production sources directory " and "test sources directory " configuration with just a "/" this makes both gradle and intellij generate the sources in the SAME directory, overwriting each other as needed. Also make sure that the "store generated sources relative to" is set to "module content root" and REBUILD the application to clear out any other sources.
The solution I proposed in previous comment was working fine in IDEA 2018.3.x but after upgrading to IDEA 2019.1 I again got this duplicate class exception...
Below is a working solution to make this work with Gradle 5.x (tested with 5.4) and IDEA 2019.1 , to implement your solution #3 which I think is the best option (do not mix gradle & idea generated output directories, and do not delegate IDEA action do Gradle )
The key point is to use excludeDirs property from idea.module extension to make IDEA ignore generated sources managed by Gradle under build/generated/sources/...
ext {
// path to Gradle generated main sources directory
gradleGeneratedMainSourcesDir = "$buildDir/generated/sources/annotationProcessor/java/main/"
// path to Gradle generated test sources directory
gradleGeneratedTestSourcesDir = "$buildDir/generated/sources/annotationProcessor/java/test/"
// path to IDEA generated sources directory
ideaGeneratedSourcesDir = "$projectDir/out/production/classes/generated"
}
idea {
module {
// exclude main & test sources generated by Gradle from project source directories
excludeDirs += file(gradleGeneratedMainSourcesDir)
excludeDirs += file(gradleGeneratedTestSourcesDir)
// include generated sources directory managed by IDEA
sourceDirs += file(ideaGeneratedSourcesDir)
generatedSourceDirs += file(ideaGeneratedSourcesDir)
}
}
See complete sample project based on this configuration here : https://github.com/mricciuti/sample-springboot-gradle-idea
You can enter to IntelliJ Settings (Preferences):
Preferences | Build, Execution, Deployment | Build Tools | Gradle | Runner
Then you tick the checkbox Delegate IDE build/run action to Gradle
Finally, you clean and build again. The issues will be resolved.
I have a KotlinJs only project which I use official kotlin2js gradle to build, and no problems there.
How to setup the output folder, currently, the building of subproject will result in a build which locates inside the subproject folder, how to set it to somewhere else? I tried:
sourceSets {
main {
kotlin.outputDir = new File(‘./out/‘)
}
}
and
sourceSets {
main.kotlin.outputDir = new File(‘./out/’)
}
No luck.
What I want is to no matter how many subprojects are there, the output folder should be in some path like ./build/projectA and ./build/projectB, rather than all in their own folder. How to do this?
Currently, it's done through the task configuration, namely setting its kotlinOptions.outputFile:
compileKotlin2Js.kotlinOptions.outputFile = "out/output.js"
It's briefly mentioned in the tutorial: Getting Started with Kotlin and JavaScript with Gradle
I have a Spring Boot Gradle project setup in Spring Tools Suite (3.7.2 RELEASE) with the following source folders:
- src/integration-test/java
- src/integration-test/resources
- src/main/java
- src/main/resources
- src/test/java
- src/test/resources`
Whenever I run the application or unit tests from within STS, I see that STS is using the resources found under src/integration-test/resources.
I see a duplicate resource warning in STS for files which exist in all 3 resource source folders. For example, I have an application.properties in all 3 source folders and I see following:
The resource is a duplicate of src/integration-test/resources/application.properties and was not copied to the output folder
If I run the application as a JAR or unit tests/integration tests from the command line (via gradle build), everything seems to use the correct resources. This makes me believe it is a problem with how STS/Eclipse is handling gradle.
Does anybody know of how I can configure STS to use the correct resource source folders when using gradle?
I think my problem may be related to (or the same as?) Spring Boot incorrectly loads test configuration when running from eclipse+gradle, https://issuetracker.springsource.com/browse/STS-3882, https://issues.gradle.org/browse/GRADLE-1777
I also tried the solution found here, but that seems to only fix Maven builds:
Spring Tool Suite finds spring-boot integration test configuration and does not start main application
I think my problem may be related to...
Yes, it is related but in my opinion not the same. That problem is caused by the runtime classpath being incorrect. This problem is an error coming from the eclipse project builder so it is a compile-time issue.
The problems are closely related though. Depending on your point of view, you could say they are the same (incorrect mixing of test and compile-time classpaths).
Here, specifically, the problem is that the eclipse builder tries to copy all the resources it finds in source folders to the project's single output folder. Each source folder has a 'application.properties'. The builder warns that it could not copy some of them because one would overwrite the other.
I think there may be a solution for this problem. But it is a solution that really should come from Gradle + ( BuildShip | STS Gradle Tooling) than from you.
It is possible in Eclipse to configure each source-folder individually to target a specific outputfolder. Maven + M2E are doing this correcty, but Gradle + (BuildsShip | STS Gradle Tooling) combdos do not.
For example this is what maven puts into the eclipse .classpath file when it configures a test resources folder:
<classpathentry excluding="**" kind="src" output="target/test-classes" path="src/test/resources">
<attributes>
<attribute name="maven.pomderived" value="true"/>
</attributes>
</classpathentry>
Notice how it explicitly sets the output folder for that entry (to something different from the project's default output folder).
You may be able to address the problem yourself by modifying the .classpath for a gradle project in a similar way. Either by doing it manually or from your build.gradle.
I'm not sure this is worth it however as you will then likely still get hit by the runtime classpath issue (since these folders will still be added to your runtime classpath, your runtime classpath will end-up with two appication.properties resources, one which will 'shadow' the other. See: https://bugs.eclipse.org/bugs/show_bug.cgi?id=482315)
I would say, the right thing to do is add a comment to the issue I linked, and hope they fix it soon as there is only so much you can do yourself by hacking the build.gradle file to modify the .classpath (this can not solve the runtime classpath issue, but in order to solve the runtime classpath issue, they would have to configure source folders to target individual output folder similar to what m2e does).
I would add this as a comment to #Kris's answer but it's too long.
I have solved the runtime classpath issue by adding the code below to my build.gradle file. The code generates an Eclipse launch configuration for the Spring Boot application class and includes only the runtime classpath (i.e. no test JARs).
My project uses the Gradle 'eclipse' plugin to generate the Eclipse project files (which I then import into Eclipse). Running the eclipseClasspath Gradle target will generate the launch file in the project's root directory.
def mainClassName = "com.example.MyApplication"
task eclipseApplicationLaunch {
group "IDE"

}
eclipseApplicationLaunch << {
def writer = new FileWriter("${mainClassName.substring(mainClassName.lastIndexOf(".")+1)}.launch")
def xml = new groovy.xml.MarkupBuilder(writer)
xml.doubleQuotes = true

I haven't modified the Eclipse .classpath file as per Kris' suggestion. Instead, I have added #Profile("test") to my test application class and #ActiveProfiles("test") to my test classes.
I am migrating a legacy application from Ant to Gradle. The requirement is to build a zip file with a certain folder structure which is used by the deployment team. I am able to create the zip file in the correct format, so-far-so-good.
I am able to open the project in Eclipse, but cannot run it. In Eclipse (and IntelliJ) I need src/main/conf to be added to Eclipse's classpath, but not be included in the JAR (e.g. if I were to run gradle jar).
This is how the project is currently structured:
src
/main
/java
/com
/example
/App.java
/resources
/applicationConfiguration.xml
/conf
/dev.properties
/staging.properties
/prod.properties
How can I add the conf folder to Eclipse's classpath so that it is not included in the JAR that Gradle creates?
Given the limitations of Gradle's EclipseClasspath API, the most straightforward solution I can think of is to declare src/main/conf as another source directory:
sourceSets.main.java.srcDir "src/main/conf"
As long as the directory doesn't contain any Java files, this won't affect the outcome of the Gradle build. However, the directory will show up as a source directory in Eclipse, and its properties files will therefore be copied into the Eclipse output directory.
Another tip. If you need it to run in Eclipse WTP, then I set the sourceDirs property of eclipse.wtp.component:
eclipse {
project {
natures 'org.eclipse.wst.common.project.facet.core.nature',
'org.eclipse.wst.common.modulecore.ModuleCoreNature',
'org.eclipse.wst.jsdt.core.jsNature'
name 'blah-blah'
}
wtp {
facet {
facet type: 'fixed', name: 'wst.jsdt.web'
facet name: 'java', version: '1.7'
facet name: 'jst.web', version: '3.0'
facet name: 'wst.jsdt.web', version: '1.0'
}
component {
sourceDirs = new HashSet([
new File(project.getProjectDir().getAbsolutePath() + "/src/main/java"),
new File(project.getProjectDir().getAbsolutePath() + "/src/main/resources"),
new File(project.getProjectDir().getAbsolutePath() + "/src/main/conf")
])
}
}
