我非常喜欢gradle和
java ..
我有一个使用sqlite的项目,它通过intellij想法运行良好,但我不能从终端运行它,它抛出一个异常:
java.lang.ClassNotFoundException: org.sqlite.JDBC
我试图在运行项目时获得intellij idea产生的进程:
/usr/lib/jvm/java-7-openjdk-amd64/bin/java -agentlib:jdwp=transport=dt_socket,server=n,suspend=y,address=42986 -Dfile.encoding=UTF-8 -cp /home/user/my_project/target/classes/main:/home/user/my_project/target/resources/main:/home/user/.gradle/caches/modules-2/files-2.1/org.xerial/sqlite-jdbc/3.7.2/7a3d67f00508d3881650579f7f228c61bfc1b196/sqlite-jdbc-3.7.2.jar Main
正如我在这里看到的想法指定classpath这是解决方案,但如何在不指定classpath的情况下运行项目的.jar文件?我的意思是可以自动gradle生成清单(因为它成功从maven org.xerial存储库中检索sqlite-jdbc)并将有效的类路径放在那里?
我想从终端成功运行它.
UPD:我不能仅通过gradle run命令从终端运行,但是我无法通过java -jar myproject.jar运行该项目.
这是我的build.gradle:
apply plugin: 'java'
apply plugin: 'maven'
apply plugin: 'idea'
apply plugin: 'application'
group = 'myproject'
version = '0.3'
description = """my project description"""
buildDir = "target"
mainClassName = "Main"
repositories {
maven { url "http://repo.maven.apache.org/maven2" }
}
dependencies {
testCompile group: 'junit', name: 'junit', version:'3.8.1'
compile 'org.xerial:sqlite-jdbc:3.7.2'
}
jar {
manifest.attributes("Main-Class": "Main")
}
/* Overwriting distribution tasks: */
task distZip(type:Zip, overwrite:true) {
archiveName = "$project.name-$version" + '.zip'
from "target/libs"
}
task distTar(type:Tar, overwrite:true) {
archiveName = "$project.name-$version" + '.tar'
from "target/libs"
}
抛出异常的Java源代码:
try {
Class.forName("org.sqlite.JDBC");
this.connection = DriverManager.getConnection(databaseName);
} catch (Exception e) {
e.printStackTrace();
}
最佳答案 我通过修改我的jar部分,在项目的分发jar文件的类路径中添加sqlite来解决这个问题:
task copyDependenciesToTarget(type: Copy) {
println 'Copying dependencies to target...'
configurations.compile.collect().each { compileDependency ->
copy {
with from (compileDependency.getPath()) {
include '*'
}
into 'target/libs/libs'
}
}
}
build.dependsOn(copyDependenciesToTarget)
jar {
manifest.attributes(
"Main-Class": "Main",
"Class-Path": configurations.compile.collect { 'libs/' + it.getName()}.join(' ')
)
}
现在gradle下载依赖项并将它们复制到libs /目录.
