尝试配置 maven clean 插件以删除我项目中的其他目录,但它无法正常工作。这是使用 maven 3.5 的简单复制。
开始使用简单的演示应用程序:https : //maven.apache.org/guides/getting-started/maven-in-five-minutes.html
修改pom.xml
配置maven-clean-plugin
:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

创建一个名为的虚拟目录 demo
mkdir demo && touch demo/hello
现在运行:
mvn package
mvn clean
您会注意到该demo
目录仍然存在。我不知道这是为什么。我已经阅读了这些 SO 文章:
我尝试运行不同的目标、阶段和 id 排列:
clean
clean:clean
clean:auto-clean
等等无济于事...
我做了一个简单的健全性检查,看看传递给 mojo 的是什么:
[DEBUG] Configuring mojo org.apache.maven.plugins:maven-clean-plugin:3.0.0:clean from plugin realm ClassRealm[plugin>org.apache.maven.plugins:maven-clean-plugin:3.0.0, parent: sun.misc.Launcher$AppClassLoader@55f96302]
[DEBUG] Configuring mojo 'org.apache.maven.plugins:maven-clean-plugin:3.0.0:clean' with basic configurator -->
[DEBUG] (f) directory = /Users/djthomps/Desktop/test/target
[DEBUG] (f) excludeDefaultDirectories = false
[DEBUG] (f) failOnError = true
[DEBUG] (f) followSymLinks = false
[DEBUG] (f) outputDirectory = /Users/djthomps/Desktop/test/target/classes
[DEBUG] (f) reportDirectory = /Users/djthomps/Desktop/test/target/classes
[DEBUG] (f) retryOnError = true
[DEBUG] (f) skip = false
[DEBUG] (f) testOutputDirectory = /Users/djthomps/Desktop/test/target/test-classes
[DEBUG] (f) verbose = true
[DEBUG] -- end configuration --
看起来我的配置选项从未设置过。为什么?
注意:我也阅读了插件文档:https : //maven.apache.org/plugins/maven-clean-plugin/examples/delete_additional_files.html。根据我的理解,我想做的事情是可能的。
也许尝试使用fileset
配置,而不是fieldset
,像这样:
<configuration>
<followSymLinks>false</followSymLinks>
<filesets>
<fileset>
<directory>*all_this_directory*</directory>
</fileset>
<fileset>
<directory>*only_some_of_this_directory*</directory>
<includes>
<include>file1_with_wildcard*</include>
<include>file2</include>
<!--continue the same...-->
</includes>
</fileset>
</filesets>
</configuration>
