最初在titan的源码里看到这个错误的。搜了一下这个错是eclipse的插件m2e的问题。不是真正的错误。

这是验证代码。这个验证代码可以让你更加了解多模块工程时maven会智能的决定最先构建哪个模块。每个模块都有自己的构建周期，xml没有写错。

可以用一个 pluginManagement 把插件包住，这样eclipse里就不报错了。但是 pluginManagement 的使用场景是父项目里定义，然后子项目里继承使用。 这里加一个 pluginManagement 只是为了看不到这个错误感觉有点名不正言不顺。 最好的办法就是忽略，不去管他。我试过了，jdk1.7+eclipse mars版本，或者 jdk1.8+eclipse neon.1版本都是会报这个错的。maven的版本都是3.3.9。

下面验证一下这个错误不影响使用。

1.新建一个maven项目叫parentProj. 

2.建子模块mod-all,mod-parent,mod-test。其中mod-all包含子模块 mod1,mod2。 mod-parent包含子模块mod-3。（titan的源码里就是个样子的）

3.在mod-parent的pom.xml里加入

 pluginManagement 

 plugins 

 plugin 

 artifactId maven-dependency-plugin /artifactId 

 executions 

 execution 

 id generate-cached-classpath /id 

 phase generate-test-resources /phase 

 goals 

 goal build-classpath /goal 

 /goals 

 configuration 

 outputFile ${project.basedir}/target/cached_classpath.txt /outputFile 

 /configuration 

 /execution 

 execution 

 id unpack-common-test-classes /id 

 phase process-test-classes /phase 

 goals 

 goal unpack /goal 

 /goals 

 configuration 

 artifactItems 

 artifactItem 

 groupId ${project.groupId} /groupId 

 artifactId mod2 /artifactId 

 version ${project.version} /version 

 classifier tests /classifier 

 outputDirectory ${project.build.directory}/test-classes /outputDirectory 

 /artifactItem 

 /artifactItems 

 /configuration 

 /execution 

 /executions 

 /plugin 

 !--This plugins configuration is used to store Eclipse m2e settings

 plugin

 artifactId lifecycle-mapping /artifactId

 configuration 

 lifecycleMappingMetadata 

 pluginExecutions

 artifactId maven-dependency-plugin /artifactId

 /pluginExecutionFilter 

 action 

 execute / 

 /action 

 /pluginExecution 

 /pluginExecutions 

 /lifecycleMappingMetadata 

 /configuration 

 /plugin 

 /plugins 

 /pluginManagement 

然后在mod3里加入

 plugin 

 artifactId maven-dependency-plugin /artifactId 

 executions 

 execution 

 id generate-cached-classpath /id 

 /execution 

 !-- 为什么此处可以解压mod2-tests.jar? 因为maven构建一开始的时候就已经reorder了。可以看到mod2是最先执行的，构建完mod2之后才开始构建mod3的 -- 

 execution 

 id unpack-common-test-classes /id 

 /execution 

 /executions 

 /plugin 

此时在 execution 处就会报

Artifact has not been packaged yet. When used on reactor artifact, unpack should be executed after packaging: see MDEP-98.

4.加入测试代码

mod1里有一个类叫ModA。里面有一个方法printA

mod2里有一个类叫ModB。里面有一个方法printB

printA里调用了ModB的printB方法

mod-test里有一个以Test开头的类。 类里有一个方法调用ModA的printA方法

mod-all

    |-- mod1

        |-- ModA

    |-- mod2

        |-- ModB

mod-parent

    |--mod3

mod-test

    |-- TestModA

5.测试

cd /d D:\WorkSpace3\parentProj

mvn clean install

以上结果可以看出
①可以看到maven会先分析项目依赖，然后调整编译的顺序，因为mod-test调用了printA， 而printA调用了printB。所以最小构建的是mod2子模块，然后再是mod1子模块。再接着是mod-test...

②maven的phase会在每个子模块里先走完。比如最先构建的是mod2。先在mod2里完整的走一遍maven的几个阶段，走到test阶段的时候会先执行mod2里的测试程序。走到package阶段就会打jar包。上面忘了说了，在mod2的src/main/test里有一个测试的类。有一个方法上加了@Test。

③正因为有了②，所以在build mod2的时候就已经打包好了mod2-0.0.1-SNAPSHOT-tests.jar，所以咱们的 mod3里在构建的时候要解压mod2-0.0.1-SNAPSHOT-tests.jar这个jar包是没问题的。因为人家的确存在呀。 所以这里报jar包不存在只能说是插件有点小瑕疵。不用管他了。

maven在构建的时候有很多阶段。比如下面在mod2中将打包的插件绑定到process-test-classes 阶段也是可以的。因为mod2在mod3之前构建，所以绑定到package或绑定到

 process-test-classes 阶段都行。

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

===========================***==================================
下面是mod2中将插件绑定到 process-test-classes 阶段的构建结果，效果是一样的：
