我试图创建一个maven原型,从预定义的模板中生成许多项目。
原型生成的模板项目是Spring Boot服务。以下是原型项目文件夹树的内容:
my-archetype
¦ pom.xml
¦
+---src
¦ +---main
¦ ¦ +---resources
¦ ¦ +---archetype-resources
¦ ¦ ¦ ¦ mvnw
¦ ¦ ¦ ¦ mvnw.cmd
¦ ¦ ¦ ¦ pom.xml
¦ ¦ ¦ ¦ rebuild.sh
¦ ¦ ¦ ¦
¦ ¦ ¦ +---src
¦ ¦ ¦ +---main
¦ ¦ ¦ ¦ +---docker
¦ ¦ ¦ ¦ ¦ Dockerfile
¦ ¦ ¦ ¦ ¦
¦ ¦ ¦ ¦ +---java
¦ ¦ ¦ ¦ ¦ __moduleClassName__ServiceApplication.java
¦ ¦ ¦ ¦ ¦ __moduleClassName__ServiceController.java
¦ ¦ ¦ ¦ ¦
¦ ¦ ¦ ¦ +---resources
¦ ¦ ¦ ¦ application.yml
¦ ¦ ¦ ¦ bootstrap.yml
¦ ¦ ¦ ¦
¦ ¦ ¦ +---test
¦ ¦ ¦ +---java
¦ ¦ ¦ __moduleClassName__ServiceApplicationTests.java
¦ ¦ ¦
¦ ¦ +---META-INF
¦ ¦ +---maven
¦ ¦ archetype-metadata.xml
¦ ¦
...
${moduleClassName}
是一个自定义属性,定义为允许自定义类名。我使用mvn clean install在我的本地存储库中安装原型,然后尝试使用mvn archetype:generate ... -DmoduleClassName=<myModule>
从中创建项目。
所有内容似乎都正常工作,除了,* .java文件被正确命名并放置在正确的pacakges中(并且其中的字符串也被属性值替换),对于其他文件,替换不会发生。特别是这是src\main\resources\archetype-resources\src\main\resources\bootstrap.yml
spring:
application:
name: ${project.artifactId}
这是src\main\resources\archetype-resources\src\main\docker\Dockerfile
FROM java:8
VOLUME /tmp
ADD ${project.artifactId}.jar app.jar
RUN bash -c 'touch /app.jar'
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
我希望${project.artifactId}
变量在两种情况下都被替换,而不会在生成的项目中发生。
这些是我的archetype-metadata.xml的相关部分:
<?xml version="1.0" encoding="UTF-8"?>
<archetype-descriptor ... >
<fileSets>
<fileSet filtered="true" packaged="true" encoding="UTF-8">
<directory>src/main/java</directory>
<includes>
<include>**/*.java</include>
</includes>
</fileSet>
<fileSet filtered="true" encoding="UTF-8">
<directory>src/main/docker</directory>
<includes>
<include>**/Dockerfile</include>
</includes>
</fileSet>
<fileSet filtered="true" encoding="UTF-8">
<directory>src/main/resources</directory>
<includes>
<include>**/*.yml</include>
</includes>
</fileSet>
<fileSet filtered="true" packaged="true" encoding="UTF-8">
<directory>src/test/java</directory>
<includes>
<include>**/*.java</include>
</includes>
</fileSet>
.
.
.
</fileSets>
<requiredProperties>
<requiredProperty key="moduleClassName"/>
</requiredProperties>
</archetype-descriptor>
答案 0 :(得分:2)
最后,我通过反复试验找到了解决方案:问题只是我使用了错误的变量名语法,使用${project.artifactId}
我应该只写${artifactId}
