java - 如何修复javac包不存在？

Question

我正在代码中创建一个Java文件，需要将其转换为类。我的文件包含以下内容:

import com.company.tpch.TpchApplication;
import com.company.tpch.TpchApplicationBuilder;
import com.speedment.runtime.core.ApplicationBuilder;
public class java {
    public void x() {
        TpchApplication app = new TpchApplicationBuilder()
                .withPassword("root")
                .withLogging(ApplicationBuilder.LogType.STREAM)
                .withLogging(ApplicationBuilder.LogType.APPLICATION_BUILDER)
                .withSkipCheckDatabaseConnectivity()
                .build();

    }
}

当我尝试使用编译文件时

javac -d . C:\Users\s\Desktop\demo\src\main\java\java.java

我有这些错误:

import com.company.tpch.TpchApplication;
                       ^
C:\Users\s\Desktop\demo\src\main\java\java.java:2: error: package com.company.tpch does not exist
import com.company.tpch.TpchApplicationBuilder;
                       ^

import com.speedment.runtime.core.ApplicationBuilder;

C:\Users\s\Desktop\demo\src\main\java\java.java:7: error: cannot find symbol
        TpchApplication app = new TpchApplicationBuilder()
        ^

  location: class java

                .withLogging(ApplicationBuilder.LogType.APPLICATION_BUILDER)
                                               ^
C:\Users\s\Desktop\demo\src\main\java\java.java:10: error: package ApplicationBuilder does not exist
                .withLogging(ApplicationBuilder.LogType.STREAM)
                                               ^

  symbol:   class TpchApplicationBuilder
  location: class java

我该如何解决？

Answer 1

您需要添加用于命令的所有类。像这样:

javac com/company/tpch/TpchApplication com/company/tpch/TpchApplicationBuilder java.java

当然，您必须根据目录结构进行更改，因为我不知道。

无论如何，我建议您使用一个可以像IntelliJ/Eclipse这样的编译一次整个项目的IDE和/或像Maven/Gradle这样的依赖工具。
