Question

请问我是maven项目和wildfly（JBoss）服务器的新手。我有一个Java EE 7项目，我使用NetBeans为Apache Tomcat 8开发。出于某种原因，我想迁移到WildFly 8.

我已经在JBoss Studio 7.1上重新创建了具有所有Maven依赖项的项目。首次尝试运行该项目将返回“禁止”。

我试图通过运行

来确保项目得到遵守和部署

这些提示包含我的环境

Apache Maven 3.2.3 (33f8c3e1027c3ddde99d3cdebad2656a31e8fdf4; 2014-08-11T21:58:10+01:00)
Maven home: /path/to/maven
Java version: 1.8.0_20, vendor: Oracle Corporation
Java home: /usr/lib/jvm/oracle_jdk_8/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.16.0-24-generic", arch: "amd64", family: "unix"

我阅读了建议的wiki，但仍无法解决问题。也许是因为我还是新人。请感谢你帮我解决这个错误。

Answer 1

您正在使用Java 8，请尝试使用Java 7，因为某些组件可能不支持Java 8。此处描述了类似的问题：maven-compilation-fails-without-explaining-why

Answer 2

我终于找到了编译失败的问题，我已经通过纠正我的POM.xml修复了我的JAVA_HOME设置错误。虽然我仍然从网址获得“禁止”，如果我无法解决它，将需要一个不同的问题线程。

<maven.compiler.executable>/absolute/path/to/bin/javac</maven.compiler.executable>

TO:

<maven.compiler.executable>${JAVA_HOME}/bin/javac</maven.compiler.executable>

我无法构建Maven项目
