我正在按照创建maven插件的教程,无法运行mvn install而不会出现错误.信息抱怨说,当注释应该为我生成时,我没有所需的mojo描述符.我正在运行maven 3.0.5并使用intellij作为我的ide.这是我的主要课程:
@Mojo(name = "modify-connector")
public class ComplianceMojo extends AbstractMojo {
@Parameter
private String artifactId;
@Parameter
private String version;
@Override
public void execute() throws MojoExecutionException, MojoFailureException {
File jar = new File(getPluginContext().get("project.build.directory") + "/"
+ getPluginContext().get("project.build.finalname") + "/" + artifactId + "-" + version);
if(jar.exists()){
getLog().info("The file exists! " + jar.getAbsolutePath());
} else {
getLog().info("The file does not exist: " + jar.getAbsolutePath());
}
}
}
这是我的pom.xml

<groupId>mysql-jdbc-compliance-maven-plugin</groupId>
<artifactId>mysql-jdbc-compliance-maven-plugin</artifactId> …我不喜欢粗略的抽象,我认为Spring已经犯下了重大的重罪.
但是如果有人可以解释"自动"配置背后的算法,我愿意忽略它.
看看spring自己的javadocs,除了说它会智能地猜测你需要什么以及有关条件bean的事情之外,它并没有给予太大的帮助.
有人知道用什么算法来确定需要加载的内容吗？
我想知道是否有一种简单的方法来确定Java类以递归方式扩展或实现的完整类型列表？
例如:
class Foo extends Bar implements I1, I2 {...}
class Bar implements I3 {...}
interface I1 extends I4, I5 {...}
interface I2 {...}
interface I3 {...}
interface I4 {...}
interface I5 {...}
class ClassUtil {
public static Set<Class<?>> getAllExtendedOrImplementedTypesRecursively(Class<?> clazz){
???
}
}
import static org.junit.Assert.*;
public class ClassUtilTest {
@Test
public void shouldEqualClasses(){
Set<Class<?>> types = ClassUtil.getAllExtendedOrImplementedTypesRecursively(Foo.class);
Set<Class<?>> checklist = new HashSet<>();
checklist.add(Foo.class);
checklist.add(Bar.class);
checklist.add(I1.class);
checklist.add(I2.class);
checklist.add(I3.class);
checklist.add(I4.class);
checklist.add(I5.class);
assertTrue(checklist.containsAll(types));
assertTrue(types.containsAll(checklist));
}
}
想想Arquillian ShrinkWrap创作助手.
更新:由于Class对象没有实现Comparable>我还需要找到一种创建Set(或类似类)的方法,而不需要实现Comparable接口(例如,仅依赖于类对象的hashcode).
更新: …
我是groovy和gradle的新手,并且想知道是否有人知道为什么我的scriplet不工作(编辑实际上它确实有效但警告仍然出现).这部分取自build.gradle脚本,intellij突出显示了这一点并抱怨它:"无法推断出参数类型".你能帮忙的话,我会很高兴 :)
task hellofun << {
[silly:'billy'].each { k, v ->
println "$k=$v"
}
}
编辑:我已经提交了一个错误请求,通知Intellij这个问题
编辑:显然这是一个已知的错误我将在修复错误后更新此错误
我有一个Java FX项目,我正在使用maven 3.0.5来构建.当我运行mvn package/install时,项目失败并抱怨包javafx.*不存在.根据我的理解,Javafx打包在Java 1.7中,因此构建不会选择它是没有意义的.当我在我的IDE(intellij)中编译它时它工作正常,之后我的maven构建也成功安装,但是我不希望每次我进行干净安装时都要通过IDE.有任何想法吗？

<project ...> …我已经配置了RepositoryRestResource一个PageAndSortingRepository访问包含复合ID的实体的on :
@Entity
@IdClass(CustomerId.class)
public class Customer {
@Id BigInteger id;
@Id int startVersion;
...
}
public class CustomerId {
BigInteger id;
int startVersion;
...
}
@RepositoryRestResource(collectionResourceRel = "customers", path = "customers", itemResourceRel = "customers/{id}_{startVersion}")
public interface CustomerRepository extends PagingAndSortingRepository<Customer, CustomerId> {}
"http://<server>/api/customers/1_1"例如,当我访问服务器时,我获得了正确的资源作为json,但是_links部分中的href是错误的,并且对于我查询的任何其他客户也是如此:"http://<server>/api/customer/1"
即:
{
"id" : 1,
"startVersion" : 1,
...
"firstname" : "BOB",
"_links" : {
"self" : {
"href" : "http://localhost:9081/reps/api/reps/1" <-- This should be /1_1
}
}
}
我想这是因为我的复合ID,但我对如何更改此默认行为感到兴奋.

每当我调用gradlew dependenciesgradle项目时,我都会得到每个配置的依赖项列表(当只配置编译时,通常包括为运行时,test和testRuntime重复多次相同的事情).
有没有办法指定特定的配置来查看依赖关系？
