Question

Maven存储库正确added，并且是必需的吗？

如果是，添加# Make the Data Actually Useable a<- c("1 8.2 JAN-1990", "2 5.3 JAN-1991", "3 6.2 JAN-1992", "4 7.8 JAN-1993", "5 6.7 JAN-1994") %>% as_data_frame() %>% separate(value, c("number", "temp", "month"), sep = " ") %>% mutate(temp = as.numeric(temp), # Now Convert the Date- Assuming First of Month? month = lubridate::dmy(paste0("1-",month))) # Base Way plot(a$month, a$temp, xlab = "Month", ylab= "Temperature") # Make the Chart in ggplot2 ggplot(a, aes(month, temp))+ geom_point()+ scale_x_date()的语法是什么？

查看此处：https://mvnrepository.com/artifact/javax.xml.xquery/xqj-api/1.0

此模块既不在Maven Central也不在JCenter存储库上托管，但是可以在其他一些存储库中找到，例如：https://mvnrepository.com/repos/springio-plugins-release。

如果要向此模块添加依赖项，只需声明一个可用的托管存储库，例如：

在Groovy DSL中：

repositories {
    jcenter()
    mavenCentral()
    maven{            
        url "http://repo.spring.io/plugins-release/"
    }
}

编辑（来自下面的评论）

科特林DSL

repositories {
    mavenCentral()
    jcenter()
    maven {
        setUrl("http://repo.spring.io/plugins-release/")
    }
}

找不到javax.xml.xquery：xqj-api：1.0
