spring - 重新打包失败：使用 Spring-Boot-Starter-Parent 版本 2.1.2.RELEASE 创建库时找不到主类

Question

我在 Spring Security 中创建了一个示例资源服务器，其中包含一个包含WebSecurityConfigurerAdapter. 当我将库的 pom 中的父spring-boot-starter-parent级从 2.0.8 更新到 2.1.2 时，spring-boot-maven-plugin我得到了可怕repackage failed: Unable to find main class 的 2.0.8 版本spring-boot-starter-parent没有这个问题。

更新：这发生在执行 mvn clean compile install 时。可以在此处找到带有父 2.0.8 的代码版本。只需将 pom.xml spring starter parent 从 2.0.8 更改为 2.1.2。

我的图书馆 pom 如下。

定义注释的类。

import org.springframework.context.annotation.Import;

import java.lang.annotation.*;

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)

@Import({ResourceServerConfig.class})
public @interface EnableExampleResourceServer {
}

WebSecurityConfigurerAdapter

我通过使用maven-compiler-plugin而不是解决了这个问题spring-boot-maven-plugin。仍然要找出spring-boot-maven-plugin导致此问题的原因。

Maven 插件详情：

    <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.6.1</version>
    <configuration>
    <source>1.8</source>
    <target>1.8</target>
    </configuration>
    </plugin>
