[英]compiling Java and groovy with java 11
Does anyone know which compiler/plugin compiles java and groovy code with the java 11 version? 有谁知道哪个编译器/插件使用java 11版本编译java和groovy代码?
I've tried GMavenPlus, Groovy eclipse compiler, and Maven's Ant plugin. 我尝试过GMavenPlus,Groovy eclipse编译器和Maven的Ant插件。 So far without success. 到目前为止没有成功。
In the end this worked: 最后这个工作:

groovy.version: 2.4.12 groovy.version:2.4.12
Here is a typical POM for the groovy-eclipse-compiler
adapter: 这是groovy-eclipse-compiler

It assumes you have src/main/groovy, src/main/java, src/test/groovy and src/test/java. 它假设你有src / main / groovy,src / main / java,src / test / groovy和src / test / java。 It is possible to have other source folder configurations with some additional XML. 可以使用其他XML文件夹配置其他源文件夹。 More details here: https://github.com/groovy/groovy-eclipse/wiki/Groovy-Eclipse-Maven-plugin 更多细节在这里: https : //github.com/groovy/groovy-eclipse/wiki/Groovy-Eclipse-Maven-plugin
There is a sample gradle project in GitHub that compiles Java and Groovy and uses Java from Groovy and viceversa. GitHub中有一个示例gradle项目 ,它编译Java和Groovy并使用来自Groovy的Java,反之亦然。 With a little changes you can make it work in Java 11. Basically use this build.gradle
: 通过一些更改,您可以使它在Java 11中工作。基本上使用此build.gradle
:
group 'de.jonashavers'
version '1.0.0'
apply plugin: 'groovy'
sourceSets {
main {
java { srcDirs = [] }
groovy { srcDirs << ['src/main/java'] }
}
}
repositories {
mavenCentral()
}
dependencies {
compile 'org.codehaus.groovy:groovy-all:2.5.7'
compile 'javax.xml.bind:jaxb-api:2.3.0'
compile 'com.sun.xml.bind:jaxb-core:2.3.0.1'
compile 'com.sun.xml.bind:jaxb-impl:2.3.0.1'
compile 'javax.activation:activation:1.1.1'
testCompile group: 'junit', name: 'junit', version: '4.12'
}
This must be the file structure: 这必须是文件结构:
The Groovy class: Groovy类:
package de.jonashavers.groovierjavacompilation
class PlainGroovy {
String language = 'groovy'
static void main(String[] args) {
String lang = "Groovy"
println(lang)
}
}
The Java Class: Java类:
package de.jonashavers.groovierjavacompilation;
class JavaExtendingGroovy extends PlainGroovy {
}
And the tests: 测试:
Java: Java的:
package de.jonashavers.groovierjavacompilation;
import org.junit.Test;
import static org.junit.Assert.assertEquals;
public class JavaTest {
@Test
public void testAccessToGroovy() {
PlainGroovy plainGroovy = new PlainGroovy();
assertEquals("groovy", plainGroovy.getLanguage());
}
@Test
public void testAccessToGroovyFromJava() {
JavaExtendingGroovy groovyFromJava = new JavaExtendingGroovy();
assertEquals("groovy", groovyFromJava.getLanguage());
}
}
Groovy: Groovy的:
package de.jonashavers.groovierjavacompilation
class GroovyTest extends GroovyTestCase {
void testAccessToGroovy() {
PlainGroovy plainGroovy = new PlainGroovy()
assertEquals 'groovy', plainGroovy.language
}
void testAccessToGroovyFromJava() {
JavaExtendingGroovy groovyFromJava = new JavaExtendingGroovy()
assertEquals 'groovy', groovyFromJava.language
}
}
I forked the project and followed the directions in this link to make it work. 我分叉了项目,并按照此链接中的说明进行操作。 Here is the fork that works in Java11 , the java11 branch . 这是在Java11 ( java11分支) 中工作的fork 。 Hope this helps: 希望这可以帮助:
