scala ide scalatest maven eclipse 开发环境配置

在eclipse建立一个scala 的meven工程，需要使用的模板是

-DarchetypeGroupId=org.scala-tools.archetypes \
-DarchetypeArtifactId=scala-archetype-simple

然后，会遇到几个问题：

1，maven的模板是什么，这个通过上述的文字已经解决。

2，Maven报Plugin execution not covered by lifecycle configuration，这个问题通过pluginManagement来解决，详见参考链接。

3，通常，maven只能够建立一个java工程，这时候，需要进行如下操作，变成一个scala工程

project name --> Configure --> Add scala nature

eclipse scala IDE自带的scala包就被加进来了，这个工程就是scala工程。详见参考链接。

4，scala IDE的scala包的版本通常与pom里面的版本并不一样，所以要把Pom里面的版本的版本号做一个修改，具体那个版本要看具体情况。要把第三方包的一些scala的依赖给去除掉

如

<groupId>org.scala-lang</groupId>

<artifactId>scala-library</artifactId>

</exclusion>

</exclusions>

配置好之后三个文件如下：

.classpath

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
	<classpathentry kind="src" output="target/classes" path="src/main/scala">
		<attributes>
			<attribute name="optional" value="true"/>
			<attribute name="maven.pomderived" value="true"/>
		</attributes>
	</classpathentry>
	<classpathentry kind="src" output="target/test-classes" path="src/test/scala">
		<attributes>
			<attribute name="optional" value="true"/>
			<attribute name="maven.pomderived" value="true"/>
		</attributes>
	</classpathentry>
	<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
		<attributes>
			<attribute name="maven.pomderived" value="true"/>
		</attributes>
	</classpathentry>
	<classpathentry kind="con" path="org.scala-ide.sdt.launching.SCALA_CONTAINER"/>
	<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/J2SE-1.5">
		<attributes>
			<attribute name="maven.pomderived" value="true"/>
		</attributes>
	</classpathentry>
	<classpathentry kind="output" path="target/classes"/>
</classpath>
