Artifact has not been packaged yet. When used on reactor art
|
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>

<!--This plugin's configuration is used to store Eclipse m2e settings

<plugin>

<pluginExecutions>

<action>
<execute />

</pluginExecution>

</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:WorkSpace3parentProj mvn clean install
输出如下：
Microsoft Windows [版本 6.1.7601] 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。
process-test-classes 阶段都行。
