我在构建我正在Spring Tool Suite中工作的项目时遇到了问题。我是Spring Tool Suite和Maven集成的新手，我总是得到以下错误
Errors running builder 'Maven Project Builder' on project 'XXX'.

我认为由于这个原因，我的大多数依赖都遇到了转移问题的失败。我错过了任何Maven设置，或者它是否存在于STS（Spring Tool Suite）中？
答案 0 :(得分：0)
已经修好了。这是由于Spring Tool Suite的Maven部分中的settings.xml未配置到正确的目录位置。这就是为什么它会抛出NullpointerException。
