Question

我已经导入了SpringPetClinic应用程序，但它在pom中显示错误。xml。我已经强制更新了Maven，但问题仍然存在。错误如下：-

未能在project spring petclinic上执行目标：无法解析项目组织的依赖项。springframework。示例：spring petclinic:jar:2.1.0。BUILD-SNAPSHOT:未能在组织上收集依赖项。springframework。boot:spring启动程序thymeleaf:jar:2.1.0。构建快照-

pom。下面给出了xml。错误显示在groupId ro下的execution标记中。isdc。wro4j。

Answer 1

你使用哪个Java版本？

在Java9或更高版本上构建SpringPetClinic时，已经报告了wroj的问题https://github.com/wro4j/wro4j/pull/1041 .

这些问题在1.8.0版之后的wroj代码中得到了解决https://github.com/wro4j/wro4j，但尚未发布具有此解决方案的版本https://github.com/wro4j/wro4j/branches .

因此，您必须自己构建wroj版本1.8.1-SNAPSHOT，并使用此版本在Java 9或更高版本上构建petclinic框架版本。

Answer 2

您在Spring Boot父依赖项中使用了错误的版本。您应该使用2.0.6-RELEASE或任何其他RELEASE版本。

 <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-parent -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.6.RELEASE</version>
    <type>pom</type>
</dependency>

希望有帮助！

Answer 3

在这种情况下，有人在PetClinic应用中面临wro4j问题。

将wro4j版本更改为1.9.0，它适用于openjdk版本“11.0.3”2019-04-16
