Maven项目结构

maven项目主体结构:

另外，Eclipse新建项目时会生成.project、.classpath及.settings目录下的文件，这些文件用于描述一个Eclipse项目,

接下来做一个简要的解析:

.project

<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
    <!-- 项目名称 -->
    <name>aaa</name>
    <!-- 此项目注释 -->
    <comment></comment>
    <!-- 引用的项目 -->
    <projects>
    </projects>
    <!-- 一系列构建指令 -->
    <buildSpec>
        <!-- 构建指令 -->
        <buildCommand>
            <!-- 指令名称 -->
            <name>org.eclipse.jdt.core.javabuilder</name>
            <!-- 参数 -->
            <arguments>
            </arguments>
        </buildCommand>
        <buildCommand>
            <name>org.eclipse.m2e.core.maven2Builder</name>
            <arguments>
            </arguments>
        </buildCommand>
    </buildSpec>
    <natures>
        <nature>org.eclipse.jdt.core.javanature</nature>
        <nature>org.eclipse.m2e.core.maven2Nature</nature>
    </natures>
</projectDescription>

.classpath

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <!-- kind="src"表明这是针对源文件的处理，即src/main/java下的源文件编译到target/classes目录下 -->
    <classpathentry kind="src" output="target/classes" path="src/main/java">
        <attributes>
            <attribute name="optional" value="true"/>
            <!-- pom derived(衍生)表明项目由pom衍生而来，受maven管理 -->
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry excluding="**" kind="src" output="target/classes" path="src/main/resources">
        <attributes>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="src" output="target/test-classes" path="src/test/java">
        <attributes>
            <attribute name="optional" value="true"/>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry excluding="**" kind="src" output="target/test-classes" path="src/test/resources">
        <attributes>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <!-- kind="con"表明这是配置，此项目使用得JDK为J2SE-1.5 -->
    <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="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
        <attributes>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <!-- kind="output"表明这是输出，此项目一般输出到target/classes下 -->
    <classpathentry kind="output" path="target/classes"/>
</classpath>

.settings

.prefs属性文件

org.eclipse.jdt.core.prefs (java development tools)关于java编译的配置
