I am new to Gradle. With Gradle 3.5, I am trying to create a war build from a java project. Below is my gradle file content.
apply plugin: 'war'
buildDir = "${rootProject.ext.buildGradle}/${project.name}"
def buildClassesDir = buildDir.getAbsolutePath() + '/classes/main'
configurations {
localLibraries
}
task copyNonJava(type: Copy, dependsOn: compileJava) {
from ('src/main/java') {
exclude '**/*.java'
include '**/*.properties'
}
from ('resources') {
include 'default_content.properties'
}
into buildClassesDir
includeEmptyDirs = false
}
task bundleJar (type: Jar, dependsOn: ['compileJava', 'copyNonJava']) {
baseName archivesBaseName
from buildClassesDir
}
task bundleWar (type: War, dependsOn: ['bundleJar']) {
baseName = project.name
from 'web'
webXml = file( 'resources/WEB-INF/web.xml' )
classpath = configurations.localLibraries
}
dependencies {
compile group: 'com.system', name: 'core', version: rootProject.version, changing: true
compile group: 'com.system', name: 'core-ui', version: rootProject.version, changing: true
compile group: 'com.persistence', name: 'persistence', version: '1.0'
compile group: 'com.surveys', name: 'survey', version: '1.0'
localLibraries fileTree("lib") {
exclude 'spring*'
}
}
When I generate war build, it adds jar files under WEB-INF/lib directory. But along with those jar files I want jar files from com.system group and jar file generated from bundleJar task. How can I achieve this?
Libraries from the compile configuration are included in classpath by default but classpath = configurations.localLibraries overrides the default value.
Instead of overriding the default classpath (classpath = ... effectively means setClasspath(...)) you can append additional files to it:
task bundleWar (type: War, dependsOn: ['bundleJar']) {
baseName = project.name
from 'web'
webXml = file( 'resources/WEB-INF/web.xml' )
classpath configurations.localLibraries
classpath bundleJar.archivePath
}
Thank you for the response on this. Really appreciate.
I have figured out a way from this. Learned that gradle follows some directory conventions so make changes to directory structure supported by gradle and made changes to the gradle script.
Here is working gradle script:
apply plugin: 'war'
buildDir = "${rootProject.ext.buildGradle}/${project.name}"
def buildClassesDir = buildDir.getAbsolutePath() + '/classes/main'
configurations {
localLibraries
}
task bundleJar (type: Jar, dependsOn: ['compileJava']) {
baseName archivesBaseName
from buildClassesDir
}
task bundleWar (type: War, dependsOn: ['bundleJar']) {
dependsOn = [ 'bundleJar' ]
baseName = project.name
from 'web'
webXml = file( 'resources/WEB-INF/web.xml' )
}
dependencies {
compile group: 'com.system', name: 'core', version: rootProject.version, changing: true
compile group: 'com.system', name: 'core-ui', version: rootProject.version, changing: true
compile group: 'com.persistence', name: 'persistence', version: '1.0'
compile group: 'com.surveys', name: 'survey', version: '1.0'
// Replace this and make sure all necessary jar dependencies are been fetched from repository instead from file system
/*localLibraries fileTree("lib") {
exclude 'spring*'
}*/
}

I switched to gradle 7.0 recently and now cannot build my projects jar, with the error
Could not get unknown property 'runtime' for configuration container of type org.gradle.api.internal.artifacts.configurations.DefaultConfigurationContainer.
`
Here is my build.gradle:
apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'application'
repositories {
mavenCentral()
}
dependencies {
implementation group: 'org.glassfish.jersey.containers', name: 'jersey-container-servlet-core', version: '2.7'

}
version = '1.0'
jar {
manifest {
attributes(
'Main-Class': 'classes.RestServer',
)
}
}
task fatJar(type: Jar) {
manifest.from jar.manifest
classifier = 'all'
from {
configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) }
} {
exclude "META-INF/.SF"
exclude "META-INF/.DSA"
exclude "META-INF/*.RSA"
}
with jar
}
artifacts {
archives fatJar
}
Gradle removed the runtime configuration after Gradle 6.x.
You can either change your fatJar task in build.gradle to refer to runtimeConfiguration (as per the Java plugin documentation):
task fatJar(type: Jar) {
manifest.from jar.manifest
classifier = 'all'
from {
// change here: runtimeClasspath instead of runtime
configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
} {
exclude "META-INF/.SF"
exclude "META-INF/.DSA"
exclude "META-INF/*.RSA"
}
with jar
}
Alternatively use a plugin that deals with fat jar building for you. I've tried Shadow a few years ago. This should also take care of files with the same names from different jars (like META-INF/LICENSE) that you may run into with your approach.
Support for runtime configuration has been stopped gradle-7.0, so configurations.runtime is not working.
Task copyAllDependencies worked for me in gradle-7.0.
Here is the example to copy dependencies into ${buildDir}/output/libs:
Add following to build.gradle.
task copyAllDependencies(type: Copy) {
from configurations.compileClasspath
into "${buildDir}/output/libs"
}
build.dependsOn(copyAllDependencies)
I hope it helps.
I created spring-boot gradle multi-module project which consisted of 3 modules: controller, service, repository. Main file was situated in Controller-module and named MySpringBootApplication.
I could build this project (using gradle build) and could get jar-file. But after starting this jar in command line I took the next error:
Error: Could not find or load main class com.epam.esm.config.MySpringBootApplication Caused by: java.lang.ClassNotFoundException: com.epam.esm.config.MySpringBootApplication.
To fix this bug I added Main-Class attributte to MANIFEST.MF file in main build.gradle but this action didn't help. So could anybody help?

The Spring Boot application executable jar file is built by bootJar task, so adding the main-class information via jar won't work either.
The bootJar task tries to create an executable jar, and that
requires a main() method. As a result, you need to disable the
bootJar task and enable the jar task (which creates an ordinary jar
rather than an executable jar) only for your no executable jar
modules.
Since you did it under subprojects section, the controller module will produce a standard jar as well. You may produce standard jars for all modules but excluding the controller module as follows:
subprojects {
if (it.name != 'controller') {
bootJar {
enabled = false
}
jar {
enabled = true
}
}
}
In addition you have to remove the jar section below
jar {
enabled = true
manifest {
attributes(
"Main-Class": "com.myproject.config.MySpringBootApplication")
}
}
and replace
bootJar {
enabled = false
}
with
bootJar {
mainClassName = 'com.myproject.config.MySpringBootApplication'
}

Creating a Multi Module Project
I've been looking for a solution for this for 4 days now with no success,
first doing the normal Gradle build task produced a tiny 7kB jar files which obviously didn't work, then i added the jar configuration for the main class:
jar {
manifest {
attributes 'Main-Class': 'Main'
}
}
It's 2MB now!
Still not good enough,
then i found the fatJar/uberJar/shadow tasks, said to be synonymous to the same thing so i tried clean then fatJar tasks on another small RMI app that will run on the server and it worked great, copied it to the main app, it produces and 60MB jar file which looks good but it won't work for some reason,
The app runs perfectly from my IDE (IntelliJIDEA) but the jar produced just does nothing.
So my last option is to consult experts so here we go:
This's the result of the clean task:
6:11:10 PM: Executing external task 'clean'...
:clean
BUILD SUCCESSFUL
Total time: 0.774 secs
6:11:11 PM: External task execution finished
'clean'.
This's the result of the fatJar task:
6:13:13 PM: Executing external task 'fatJar'...
Note: Some input files use unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

Making sure a main class is set
Making sure the main class has the same full class name as the one defined
Checking the manifest is valid
Checking the class exists
JavaFX may need a plugin
In the end the last one fixed the issue this was the plugin that fixed the issue.
This was the last comment in the chain:
#jrtapsell Well, this's embarrassing but i'v found the problem, i was unaware that JavaFX apps need a special plugin for Gradle, Using the FiberFox Plugin solved my issue, Thanks for your efforts and may you post answers so that i could upvote you if you like
I need to add jar generated from running application into same application classpath.

Here customProp is variable to get the jar name dynamically while run the gradle build.(gradle build -P customProp=XXXXtask ).
BottomLine : I cannot able to access the classes from the dynamically generate jar.So the Question becomes - How can i add the jar file into running application on runtime??.Thanks in advance.
I'd like to create a exe file, without having to put all required libraries beside the exe.
Formerly with ant I created a self-contained jar file with one-jar and then wrapped this into a exe file with launch4j.
Gradle has plugins for both and standalone both work very well with almost no configuration.
But how can I manage to use the created one-jar as the input for launch4j?
This is my current buildfile:
apply plugin: 'java'
apply plugin: 'launch4j'
apply plugin: 'gradle-one-jar'
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'edu.sc.seis.gradle:launch4j:1.0.6'
classpath 'com.github.rholder:gradle-one-jar:1.0.4'
}
}
launch4j {
mainClassName = "de.my.umkopierer.Umkopierer"
launch4jCmd = "C:/Program Files (x86)/Launch4j/launch4j"
jar = "lib/Umkopierer-1.0.jar"
headerType = "console"
dontWrapJar = false
}
sourceCompatibility = 1.7
version = '1.0'
jar {
manifest {
attributes 'Implementation-Title': 'Umkopierer', 'Implementation-Version': version
}
}
repositories {
mavenCentral()
}
dependencies {
compile group: 'commons-collections', name: 'commons-collections', version: '3.2'
compile 'com.google.guava:guava:18.0'
compile 'com.fasterxml.jackson.core:jackson-core:2.4.4'
compile 'com.fasterxml.jackson.datatype:jackson-datatype-jdk7:2.4.4'
compile 'com.fasterxml.jackson.core:jackson-databind:2.4.4'
testCompile group: 'junit', name: 'junit', version: '4.+'
}
task oneJar(type: OneJar) {
mainClass = "de.stiffi.umkopierer.Umkopierer"
}
I solved this by making the launch4j task 'createExe' dependent on the onejar/fatjar (or any other fat jar creation method). E.g.:
tasks.createExe.dependsOn('oneJar')
task launch4j(overwrite: true, dependsOn: ['createExe']){
}
Also I think that your gradle build file should contain a main class attribute like
manifest {
attributes 'Main-Class':'com.example.MyMainClass'
}
(at least that's the case if you are using the fatjar gradle plugin).
