我想在一個非常簡單的例子，基本上遵循this one焊接工作。但是，我無法得到它的工作。焊接與StartMain不起作用
我使用gradle來建造。這是我的build.gradle：
apply plugin: 'java'
version='1.0-SNAPSHOT'
repositories {
mavenCentral()
}
task wrapper(type: Wrapper) {
gradleVersion = '1.8'
}
jar {
dependsOn configurations.runtime
from { configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) } }
}
task hello(type: JavaExec) {
main = 'org.jboss.weld.environment.se.StartMain'
classpath = sourceSets.main.runtimeClasspath
}
dependencies {
compile 'org.jboss.weld.se:weld-se:2.0.4.Final'
}
我有這些文件在src文件夾中。
./src/main/java/weldse/HelloWorld.java
./src/main/resources/META-INF/beans.xml
內容如下。
HelloWorld.java
package weldse;
import org.jboss.weld.environment.se.events.ContainerInitialized;
import javax.enterprise.event.Observes;
public class HelloWorld {
public void printHello(@Observes ContainerInitialized event) {
System.out.println("Hello, World");
}
}
的beans.xml
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
version="1.1" bean-discovery-mode="all">
</beans>
當我運行gradle hello，我沒有得到輸出Hello, World但這些消息的BUILD SUCCESSFUL：
[main] INFO org.jboss.weld.Version - WELD-000900 2.0.4 (Final)
[main] INFO org.jboss.weld.Bootstrap - WELD-000101 Transactional services not available. Injection of @Inject UserTransaction not available. Transactional observers will be invoked synchronously.

[main] WARN org.jboss.weld.interceptor.util.InterceptionTypeRegistry - Class 'javax.ejb.PrePassivate' not found, interception based on it is not enabled
但是，當我直接使用java運行它時，出現異常。這是完整的堆棧跟蹤。

在我看來，有是導致異常的InstanceManager歧義。但是，我不確定。無論如何，你知道如何做這個工作嗎？非常感謝你。
