我必须在同一个Maven项目中使用Annotation Processing(apt)和AspectJ.
两者都适合自己,但我需要根据apt创建的代码创建方面.所以我需要二进制编织(原始源文件由apt扩展).如何在maven项目中启用二进制编织?
我知道唯一的标准选项是使用weaveDependencies参数提供依赖项,但这很糟糕.还有其他方法吗?
好吧,我可以使用Maven Antrun Plugin嵌入AspectJ ant tasks,但我不想诉诸于此.
解决方法:
我显然是唯一能够回答我自己问题的人.
我已经使用Maven Antrun Plugin通过ant编译AspectJ.这是我的pom片段:
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.4</version>
<dependencies>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjtools</artifactId>
<version>${aspectj.version}</version>
</dependency>
</dependencies>
<executions>
<execution>
<id>ajc-compile</id>
<phase>process-classes</phase>
<configuration>
<tasks>
<property name="aspectj.sourcepath"
value="${project.basedir}/src/main/aspect" />
<property name="aspectj.binarypath"
value="${project.build.outputDirectory}" />
<property name="aspectj.targetpath"
value="${project.build.directory}/aspectj-classes" />
<property name="scope_classpath" refid="maven.compile.classpath" />
<property name="plugin_classpath" refid="maven.plugin.classpath" />
<ant antfile="ajc-ant.xml" />
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
<execution>
<id>ajc-test-compile</id>
<phase>process-test-classes</phase>
<configuration>
<tasks unless="maven.test.skip">
<property name="aspectj.sourcepath"
value="${project.basedir}/src/test/aspect;${project.basedir}/src/main/aspect" />
<property name="aspectj.binarypath"
value="${project.build.testOutputDirectory}" />
<property name="aspectj.targetpath"
value="${project.build.directory}/aspectj-test-classes" />
<property name="scope_classpath" refid="maven.test.classpath" />
<property name="plugin_classpath" refid="maven.plugin.classpath" />
<ant antfile="ajc-ant.xml" />
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
我首先编译java类(让APT做它的东西),使用编译的类作为aspectj的二进制输入,将aspectj编译到一个新文件夹中,并将生成的编织类移动到原始的编译目录,覆盖非aspectj类.这是我的ant XML文件(很好的部分是我可以将它用于编译和测试编译):
<project basedir="." default="ajc">
<path id="classpath">
<pathelement path="${scope_classpath}" />
<pathelement path="${plugin_classpath}" />
</path>
<taskdef
classname="org.aspectj.tools.ant.taskdefs.AjcTask"
name="iajc" classpathref="classpath" />
<target name="ajc">
<iajc
sourceroots="${aspectj.sourcepath}"
inpath="${aspectj.binarypath}"
destdir="${aspectj.targetpath}"
classpathref="classpath"
source="1.6"
target="1.6"
/>
<move todir="${aspectj.binarypath}">
<fileset dir="${aspectj.targetpath}">
<include name="**/*.class" />
</fileset>
</move>
</target>
</project>
在下一步中,我现在已经创建了一个Maven插件,可以在内部完成所有这些蚂蚁调用.虽然我不能在这里分享代码,但我将展示它如何简化POM配置:
<plugin>
<groupId>com.myclient.maven.plugins</groupId>
<artifactId>maven-ajc-plugin</artifactId>
<version>1.0-SNAPSHOT</version>
<executions>
<execution>
<id>compile-ajc</id>
<goals>
<goal>compile</goal>
</goals>
</execution>
<execution>
<id>testcompile-ajc</id>
<goals>
<goal>test-compile</goal>
</goals>
<configuration>
<aspectSourcePath>${project.basedir}/src/main/aspect</aspectSourcePath>
</configuration>
</execution>
</executions>
<configuration>
</configuration>
</plugin>
使用ANT / GMaven integration,可以很容易地组合Maven,Groovy和Ant的功能.
