AspectJ + Gradle configuration
提问by Kao
I'd like to use AspectJ in Gradle project (it's not an Android project - just a simple Java app).
我想在 Gradle 项目中使用 AspectJ（它不是一个 Android 项目——只是一个简单的 Java 应用程序）。
Here is how my build.gradle looks like:
这是我的 build.gradle 的样子：
apply plugin: 'java'
buildscript {
repositories {
maven {
url "https://maven.eveoh.nl/content/repositories/releases"
}
}
dependencies {
classpath "nl.eveoh:gradle-aspectj:1.6"
}
}
repositories {
mavenCentral()
}
project.ext {
aspectjVersion = "1.8.2"
}
apply plugin: 'aspectj'
dependencies {
//aspectj dependencies
aspectpath "org.aspectj:aspectjtools:${aspectjVersion}"
compile "org.aspectj:aspectjrt:${aspectjVersion}"
}
The code compiles, however the aspect seems to not be weaved. What could be wrong?
代码编译，但是方面似乎没有被编织。可能有什么问题？

I have been struggled with this for a while, so this the config I use and works well.
我已经为此苦苦挣扎了一段时间，所以这是我使用的配置并且运行良好。
In your configuration do this.
在您的配置中执行此操作。
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.
在您的依赖项中使用以下配置。如果您不使用 spring fwk，则不需要 Spring 依赖项。
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
我不使用插件我使用 ant 和 aspectj 编译器来做到这一点，可能会有一个简单的方法

Just want to add the so called "official" plugin for AspectJ mentioned by Archie.
只是想为Archie提到的AspectJ添加所谓的“官方”插件。
Here's some gradle script example on how to do it:
这是有关如何执行此操作的一些 gradle 脚本示例：
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 :
但是，它似乎只支持 Java 8 及更高版本。当您使用 java 7 构建它时，出现错误：
java.lang.UnsupportedClassVersionError: aspectj/AspectJGradlePlugin : Unsupported major.minor version 52.0

Looks like there is a new "official" gradle plugin for AspectJ:
看起来 AspectJ 有一个新的“官方”gradle 插件：
https://plugins.gradle.org/plugin/aspectj.gradle
https://plugins.gradle.org/plugin/aspectj.gradle
Unfortunately the documentation is minimal. I haven't tried it myself.
不幸的是，文档很少。我自己没试过。

A bit ugly, but short and does not require additional plugins or configurations. Works for me:
有点丑，但很短，不需要额外的插件或配置。对我有用：
Add aspectjweaverdependency ti Gradle build script. Then in the task you need it find the path to its jar and pass as javaagentin jvmArgs:
添加aspectjweaver依赖项 ti Gradle 构建脚本。然后在任务，你需要找到它的路径，它的罐子，并通过如javaagent在jvmArgs：
dependencies {
compile "org.aspectj:aspectjweaver:1.9.2"
}
test {
group 'verification'
doFirst {
def weaver = configurations.compile.find { it.name.contains("aspectjweaver") }
jvmArgs = jvmArgs << "-javaagent:$weaver"
}
}
Add aop.xmlfile to the resources\META-INF\folder with the specified Aspect class:
将aop.xml文件添加到resources\META-INF\具有指定 Aspect 类的文件夹中：
<aspectj>
<aspects>
<aspect name="utils.listener.StepListener"/>
</aspects>
</aspectj>
Example of an aspect:
一个方面的例子：
package utils.listener
import org.aspectj.lang.JoinPoint
import org.aspectj.lang.annotation.*
import org.aspectj.lang.reflect.MethodSignature
@Aspect
@SuppressWarnings("unused")
public class StepListener {
/* === Pointcut bodies. Should be empty === */
@Pointcut("execution(* *(..))")
public void anyMethod() {
}
@Pointcut("@annotation(org.testng.annotations.BeforeSuite)")
public void withBeforeSuiteAnnotation() {
}
}

Adding this in my build.gradle file worked for me.
在我的 build.gradle 文件中添加这个对我有用。
project.ext {
aspectjVersion = '1.8.12'
}
apply plugin: "aspectj.gradle"
buildscript {
repositories {
maven {
url "https://plugins.gradle.org/m2/"
}
}
dependencies {
classpath "gradle.plugin.aspectj:gradle-aspectj:0.1.6"
}
}
Doing a gradle assembleinjected the code defined in the aspect.
执行gradle assemble注入方面定义的代码。

For gradle 5 u can use this 'official' plugin. there you can find a working example too.
对于 gradle 5，你可以使用这个“官方”插件。在那里你也可以找到一个工作示例。
