AspectJ + Gradle configuration
I have been struggled with this for a while, so this the config I use and works well.
In your configuration do this.
configurations {
ajc
aspects
aspectCompile
compile{
extendsFrom aspects
}
}
In your dependencies use the following configuration. Spring dependencies are not needed if you are not using spring fwk.
dependencies {
//Dependencies required for aspect compilation
ajc "org.aspectj:aspectjtools:$aspectjVersion"
aspects "org.springframework:spring-aspects:$springVersion"
aspectCompile "org.springframework:spring-tx:$springVersion"
aspectCompile "org.springframework:spring-orm:$springVersion"
aspectCompile "org.hibernate.javax.persistence:hibernate-jpa-2.1-api:$hibernateJpaVersion"
}
compileJava {
sourceCompatibility="1.7"
targetCompatibility="1.7"
//The following two lines are useful if you have queryDSL if not ignore
dependsOn generateQueryDSL
source generateQueryDSL.destinationDir
dependsOn configurations.ajc.getTaskDependencyFromProjectDependency(true, "compileJava")
doLast{
ant.taskdef( resource:"org/aspectj/tools/ant/taskdefs/aspectjTaskdefs.properties", classpath: configurations.ajc.asPath)
ant.iajc(source:"1.7", target:"1.7", destDir:sourceSets.main.output.classesDir.absolutePath, maxmem:"512m", fork:"true",
aspectPath:configurations.aspects.asPath,
sourceRootCopyFilter:"**/.svn/*,**/*.java",classpath:configurations.compile.asPath){
sourceroots{
sourceSets.main.java.srcDirs.each{
pathelement(location:it.absolutePath)
}
}
}
}
}
I dont use the plugin I use the ant and aspectj compiler to do that, probably there will be an easy way
Just want to add the so called "official" plugin for AspectJ mentioned by Archie.
Here's some gradle script example on how to do it:
apply plugin: 'java'
sourceCompatibility = '1.8'
[compileJava, compileTestJava]*.options*.encoding = 'UTF-8'
if (!hasProperty('mainClass')) {
ext.mainClass = 'com.aspectz.Main'
}
buildscript {
repositories {
maven {
url "https://plugins.gradle.org/m2/"
}
}
dependencies {
classpath "gradle.plugin.aspectj:gradle-aspectj:0.1.6"
//classpath "gradle.plugin.aspectj:plugin:0.1.1"
//classpath "gradle.plugin.aspectj:gradle-aspectj:0.1.1"
}
}
ext {
aspectjVersion = '1.8.5'
}
apply plugin: "aspectj.gradle"
repositories {
mavenCentral()
}
dependencies {
testCompile group: 'junit', name: 'junit', version: '4.10'
compile("log4j:log4j:1.2.16")
compile("org.slf4j:slf4j-api:1.7.21")
compile("org.slf4j:slf4j-log4j12:1.7.21")
compile("org.aspectj:aspectjrt:1.8.5")
compile("org.aspectj:aspectjweaver:1.8.5")
}
However, it seems that it only supports Java 8 and above. As when you use java 7 to build it, it got error :
java.lang.UnsupportedClassVersionError: aspectj/AspectJGradlePlugin : Unsupported major.minor version 52.0
Looks like there is a new "official" gradle plugin for AspectJ:
https://plugins.gradle.org/plugin/aspectj.gradle
Unfortunately the documentation is minimal. I haven't tried it myself.
