[英]Maven Groovy and Java + Lombok
I am trying to add groovy to an existing Java Maven project that leverages Lombok. 我正在尝试将groovy添加到利用Lombok的现有Java Maven项目中。 Unfortunately when I enable the groovy-maven-eclipse compiler with the pom fragment below, my lombok annotated java files fail to compile.
不幸的是,当我使用下面的pom片段启用groovy-maven-eclipse编译器时,我的lombok注释的java文件无法编译。 As far as I can tell, Lombok is not participating in the compilation of java files at all.
据我所知,Lombok根本没有参与java文件的编译。
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.1</version>
<configuration>
<compilerId>groovy-eclipse-compiler</compilerId>
<verbose>true</verbose>
</configuration>
<dependencies>
<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-eclipse-compiler</artifactId>
<version>2.6.0-01-SNAPSHOT</version>
</dependency>
</dependencies>
</plugin>
I should also point out that while in eclipse (with m2e) everything works fine. 我还应该指出,在eclipse中(使用m2e)一切正常。 My problem arises when I try to do a mvn package.
当我尝试做一个mvn包时,我的问题出现了。
@Todd: The groovy-eclipse-compiler is the best choice if you don't need to developp maven plugin with some groovy tooling (see http://groovy.codehaus.org/Groovy-Eclipse+compiler+plugin+for+Maven ). @Todd:如果你不需要使用一些常规工具开发maven插件,那么groovy-eclipse-compiler是最好的选择(参见http://groovy.codehaus.org/Groovy-Eclipse+compiler+plugin+for+Maven )。
@Ambience: you reached the issue related at http://jira.codehaus.org/browse/GRECLIPSE-1293 . @Ambience:您在http://jira.codehaus.org/browse/GRECLIPSE-1293上遇到了相关问题。 This bug is now fixed with latest groovy-eclipse-compiler 2.6.1-01-SNAPSHOT.
现在用最新的groovy-eclipse-compiler 2.6.1-01-SNAPSHOT修复了这个bug。
Note : The latest version available is now 2.9.1-01 , see http://docs.groovy-lang.org/latest/html/documentation/tools-groovyeclipse.html 注意 :最新版本现在是2.9.1-01 ,请参阅http://docs.groovy-lang.org/latest/html/documentation/tools-groovyeclipse.html
You have to modify your pom like this: 你必须像这样修改你的pom:
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<compilerId>groovy-eclipse-compiler</compilerId>
<verbose>true</verbose>
<fork>true</fork>
<compilerArguments>
<javaAgentClass>lombok.launch.Agent</javaAgentClass>
</compilerArguments>
</configuration>
<dependencies>
<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-eclipse-compiler</artifactId>
<version>2.9.1-01</version>
</dependency>
<!-- for 2.8.0-01 and later you must have an explicit dependency on groovy-eclipse-batch -->
<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-eclipse-batch</artifactId>
<version>2.3.7-01</version>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.16.4</version>
</dependency>
</dependencies>
</plugin>
The mandatory parts: 强制性部分:
<fork>true</fork>
<compilerArguments>
<javaAgentClass>lombok.launch.Agent</javaAgentClass>
</compilerArguments>
The added dependency on lombok inside the maven-compiler-plugin 在maven-compiler-plugin中增加了对lombok的依赖
Edit: update versions 编辑:更新版本
The correct answer at the time of writing it was and still is the accepted one . 在撰写本文时,正确的答案是并且仍然是被接受的答案。 I have no intention of stealing that reputation, but I also do not want to edit it once more because it is kind of outdated (eg link to Codehaus), so I would basically have to rewrite it anyway just so as to update it.
我无意窃取这种声誉,但我也不想再次编辑它,因为它有点过时(例如链接到Codehaus),所以我基本上不得不重写它,以便更新它。
Here is a Maven POM based on 这是一个基于Maven的POM
It also contains the plugin repository configuration for the latest Groovy Eclipse version not found on Maven Central. 它还包含在Maven Central上找不到的最新Groovy Eclipse版本的插件存储库配置。
I am using this setup for my Spock + Geb tests, by the way. 顺便说一下,我正在使用这个设置进行Spock + Geb测试。
