java maven exec-maven-plugin无法在mvn全新安装上执行 [英] java maven exec-maven-plugin not executing on mvn clean install

问题描述

关注上一个问题: 测试阶段之前的Maven运行类:exec-maven-plugin exec:java不执行类.

我正在jenkins盒子上运行用maven构建的jUnit4测试.在构建测试阶段之前，我需要运行特定的主方法Java程序.目的是在测试运行之前还原测试数据库.

I am running jUnit4 tests, built with maven, on a jenkins box. I need to run a specific main-method java program before before the test phase of my build. The intent is to restore a test database before the tests run.

如果我运行该exec分配给的确切阶段，则我的类将按预期执行；但是当我运行整个构建时，我的类不会执行:

If I run the exact phase this exec is assigned to, my class executes as expected; but when I run the whole build, my class does not execute:

具体说来，它运行于:
mvn -X exec:java generate-test-resources

Specifically, it runs with:
mvn -X exec:java generate-test-resources

但不能与以下内容一起运行:
mvn -X -e install
-或-
mvn -X -e clean install

But does not run with:
mvn -X -e install
-- or --
mvn -X -e clean install

pom.xml:我的pom.xml文件包括:

pom.xml: My pom.xml file includes:

                <mainClass>main.java._tools.BuildTestEnvironment</mainClass>
            </configuration>
        </plugin>
    </plugins>
</pluginManagement>

生命周期默认值: 我还不喜欢Maven的生命周期.日志报告为:

Lifecycle default: I have not futzed with maven's lifecycle. The log reports it as:

[DEBUG] Lifecycle default -> [
    validate,
    initialize,
    generate-sources,
    process-sources,

    process-resources,

    generate-test-sources,

推荐答案

使用在<pluginManagement>下定义的插件，实际上是在告诉maven在调用插件时将在整个项目中使用哪个版本的插件.我通常希望<pluginManagement>标签出现在父pom中.

With your plugin defined under the <pluginManagement>, you are actually telling maven which version of the plugin you will use throughout your project when you will invoke the plugin. I would normally expect the <pluginManagement> tag to be present in the parent pom.

要调用插件-只需放置<plugins/>元素.它可能会也可能不会从

To invoke the plugin - simply put the <plugins/> element. It may or may not be inherited from a

因此要使用该插件，您只需要通过插入即可调用该插件

Hence to use the plugin, you just need to invoke the plugin by putting

<plugins>
        <plugin>            
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>exec-maven-plugin</artifactId>
            <version>1.3</version>
            <executions>
                <execution>
                    <id>build-test-environment</id>
                    <phase>generate-test-resources</phase>          
                    <goals>
                        <goal>java</goal>           
                    </goals>
                </execution>
            </executions>
            <configuration>
                <mainClass>main.java._tools.BuildTestEnvironment</mainClass>
            </configuration>
        </plugin>
    ...AnyOtherPlugin
    <plugins>

没有任何<pluginManagement>标记
