我一辈子都想不出如何让Spring项目在IDE之外运行。我正在使用Gradle。我上下搜索,包括pply插件:“应用程序”字样,我看到生成了Jars,但是当我通过gradlew run运行时,它死于说找不到文件。
1)我需要一个单独的build.gradle文件来运行它吗?在尝试运行之前,我不得不取出大量其他项目内容(必须使用#删除所有内容)
2)为什么不起作用?我什至需要一个build.gradle文件吗?您如何从Spring IDE转到以最简单的方式在命令行上运行的程序?

感谢您的回复。我使用了disk.util.DiskBenchmark并仅修改了该特定文件,因为我需要添加一个缓存,因此我的名称为DiskMark.Java。这是我的DiskMark的前几行

import java.io.RandomAccessFile;

import com.google.common.cache.Cache;
import org.apache.activemq.util.RecoverableRandomAccessFile;
/**
* This class is used to get a benchmark the raw disk performance.
*/
public class DiskMark {
private static final boolean SKIP_METADATA_UPDATE =
Boolean.getBoolean("org.apache.activemq.file.skipMetadataUpdate");
boolean verbose;
// reads and writes work with 4k of data at a time.
int bs = 1024 * 4;
// Work with 100 meg file.
long size = 1024 * 1024 * 500;
long sampleInterval = 10 * 1000;
static Cache<Long, byte[]> cache;
static Callable<byte[]> loader;
static ArrayList<Long> longIndexList;
boolean enableCache = true;
public static void main(String[] args) {
我应该采取不同的方法吗?它在IDE中运行良好

我将Java文件移动到src / main / java下的新软件包中,软件包名称为DiskCharacterize,类名称为DiskMark。 仍然不起作用。
我用这个build.gradle
/**

*
* The tests are forked from Guava commit e370dde.
*/
apply plugin: 'application'

我切换到gs-gradle-0.1.0.jar存在的/ build / libs /目录。我用这个build.gradle 填充这个目录

到底是怎么回事?我需要运行它,而无法终生解决
编辑4:
gradle运行不起作用,即使添加了apply插件:“java”,插件应用程序仍然隐式调用Java插件。
但是,我让它运行了。我去了../build/distributions/文件夹,其中同时包含guava-2.3.1-SNAPSHOT.tar和guava-2.3.1-SNAPSHOT.zip,我解压缩了zip文件,找到了一个bash文件并简单地执行了它。程序运行了。我不知道为什么gradle run不起作用(如果您有任何想法,我仍然很想明白)。谢谢大家的帮助,谢谢本·M。
最佳答案
根据新信息编辑的答案:
基于Gradle Application Plugin Documentation,运行命令针对“主源集”运行。您尝试运行的类位于src / test下,这不是Gradle默认源位置的一部分(并且基于名称,如果是,则将成为测试源位置的一部分)。请查看Gradle Java Plugin文档(45.2),以获取关于什么是源集以及如何更改它们的更好的描述,这比我在这里可能给出的要好:)
简短的回答/建议:将包和文件从src / test移到名为src / main / java的源文件夹中,以允许Gradle运行找到所需的类(您可以替代地重新配置源集,但这似乎有点过头了对于你的情况)
旧答案(基于对Typo尝试使用库提供的类的错误评估):
I am assuming that you are trying to run the class
org.apache.activemq.store.kahadb.disk.util.DiskMark
as your main class. Based on the name of the class, I am guessing you are trying to use this from the activemq-kahadb dependency in your build.gradle file (as opposed to writing it yourself with a nearly identical package structure to the activemq-kahadb structure)For the version you are dependent on, there does not appear to be a class with that name (based on the package tree). I didn't find any version of ActiveMQ with a class of that name. There is a class called
org.apache.activemq.store.kahadb.disk.util.DiskBenchmark
which contains a main method - was that what you meant to invoke?
