如何从命令行运行从Intellij创建的javajar

jar intellij-idea java

Atihska · 技术社区 · 6 年前

this 所以张贴和遵循的步骤,但我仍然无法运行它。

Directory_where_jar_is_located $ java -jar Main.java
Error: Unable to access jarfile IcerbergRun
Directory_where_jar_is_located$ java -jar ProjectName.jar 
Error: Could not find or load main class IcebergRun

之后需要做什么?这些依赖关系是什么?另外,我正在共享pom.xml,它包含一些项目所需的库。

我用java创建了一个测试项目,构建并执行了jar。

最初项目的结构如下所示。这个 out 目录只包含生产目录。

现在单击文件->项目结构->人工产品。点击 + 在左上角的左侧导航窗格旁签名。

+ 签名并选择Jar->从具有依赖项的模块。。。。将出现一个对话框,如下所示:

现在选择 Main Class 然后选择 radio button extract to the target JAR 然后单击 OK . 您将看到以下内容 :

检查 Include in project build checkbox 然后单击 Apply->Ok .

Build->Build Project . 现在你可以看到了 out directory 有 artifacts sub-directory 会有相应的罐子

现在在伦敦的终点站 intelliJ 进入jar所在的目录并执行命令 java -jar JAR_NAME.jar 你可以看到主函数被执行了。

Could not load main class 所以我在命令行上尝试了我的整个java项目,并生成了适合我的JAR。

步骤如下:

1.在ec2上安装maven https://gist.github.com/sebsto/19b99f1fa1f32cae5d00

$sudo wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo
$sudo sed -i s/\$releasever/6/g /etc/yum.repos.d/epel-apache-maven.repo
$sudo yum install -y apache-maven
$mvn âversion

$sudo yum install java-1.8.0-openjdk-devel
$yum install zip

3.这样做可以创建maven项目 http://www.mkyong.com/maven/how-to-create-a-java-project-with-maven/

$mvn archetype:generate -DgroupId=com.package.name -DartifactId=java-project -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

4.编辑代码文件和pom.xml。您可以在IntelliJ中打开项目并进行编辑。

5.MAVEN构建:从java项目的根目录运行

java-project$mvn package or mvn clean package

6.删除生成后创建的这些文件

https://gist.github.com/hkhamm/88923412992d284580ea

java-project$zip -d target/iceberg-project-1.0-SNAPSHOT.jar META-INF/*.RSA META-INF/*.DSA META-INF/*.SF

7.运行JAR

java-project$java -cp target/java-project-1.0-SNAPSHOT.jar com.project.name.App
