Linux Mint上的IntelliJ IDEA中构建过程异常终止

我像往常一样安装在Linux Mint上的IntelliJ IDEA与Kotlin一起工作，当我建立我的应用程序，我得到这个错误： Error:Abnormal build process termination: /media/ali/691fe16b-e074-4fb6-b990-e59e82b571cb/jdk1.8.0_131/bin/java -Xmx700m

我已经从oracle下载了JDK，并对提取的文件夹做了IntelliJ IDEA引用，我不知道这是否是错误的。 另一个问题是我没有Kotlin的任何运行配置，当我配置一个应用程序配置并命名具有主类的类时，它说这个类没有主要的方法。

我在Android与Kotlin错误

使用ant与kotlin编译器jar进行连接时发生Java编译器错误

我有一个关于java编译器的非常奇怪的问题。 所以我所做的是在编译时将Kotlin编译器kotlin-compiler-embeddable-1.2-M2.jar到类路径中，不幸的是这会使NullPointerException kotlin-compiler-embeddable-1.2-M2.jar崩溃。 正如你可以从例外中看到的，我使用ANT，但我不认为它是相关的。 最有趣的部分是，如果我用java9编译代码，代码仍然不能编译，但异常是不同的。 我也认为这与我正在编译的源码无关，因为我将该jar添加到具有相同类的另一个项目，并编译并运行。 我用-verbose运行了javac命令，就像那样 <javac executable="${build_java_home}/${java_command_dir_name}/javac" fork="yes" srcdir="@{srcdir}" destdir="@{destdir}" excludes="@{excludes}" source="1.8" target="1.8" deprecation="yes" includeantruntime="false" debug="true" encoding="utf-8" verbose="true"></javac> Java 8 [javac] [loading ZipFileIndexFileObject[kotlin-compiler-embeddable-1.2-M2.jar(org/jetbrains/kotlin/cli/common/messages/MessageCollector$Companion.class)]] [javac] [loading ZipFileIndexFileObject[kotlin-compiler-embeddable-1.2-M2.jar(org/jetbrains/kotlin/cli/common/messages/MessageCollector$DefaultImpls.class)]] [javac] Exception in thread "main" java.lang.RuntimeException: java.lang.NullPointerException [javac] at com.sun.tools.javac.main.Main.compile(Main.java:559) [javac] at com.sun.tools.javac.main.Main.compile(Main.java:381) [javac] at com.sun.tools.javac.main.Main.compile(Main.java:370) [javac] at com.sun.tools.javac.main.Main.compile(Main.java:361) [javac] at com.sun.tools.javac.Main.compile(Main.java:56) [javac] at com.sun.tools.javac.Main.main(Main.java:42) [javac] Caused […]

AspectJ类型层次结构中的kotlin委托编译器问题

注意 TLDR; 我发现这只是一个环境问题。 带有kotlin代码的JAR具有旧的类文件，导致编译器100％正确处理的意外问题。 我认为JAR中还有另外一个类文件，我试图依赖这个叫做SimpleLink的类，而不是一个接口。 当我删除.kt文件时，Gradle Kotlin编译插件没有删除这些类。 LPT：在尝试发布之前运行Gradle clean任务，即使您只发布到maven本地。 我有一个与使用另一个项目的kotlin类的代码连接的aspectj问题。 aspectJ编译器运行1.8.6版本。 我特别的问题是，我一直看到这样的： Type mismatch: cannot convert from element type ExtendedSimpleLink to SimpleLink 我有一个类型层次结构，其中ExtendedSimpleLink extends LinkDecorator ，其中ExtendedSimpleLink extends LinkDecorator在LinkDecorator中编写并在另一个项目中编译， ExtendedSimpleLink是使用aspectj编译器编译的java。 LinkDecorator看起来像这样： abstract class LinkDecorator( private val decorated : SimpleLink ) : SimpleLink by decorated { override fun hashCode(): Int = decorated.hashCode() override fun equals(other: Any?): Boolean […]

为什么==会在Kotlin的不同类型中产生编译错误

下面的代码不能被编译： if ("2" == 3) { //do something } Error: Kotlin: Operator '==' cannot be applied to 'String' and 'Int' 然而，Kotlin文档说，这是结构性的平等，被翻译成a?.equals(b) ?: (b === null) ： https a?.equals(b) ?: (b === null) 。 那么这里究竟发生了什么？ 它是如何工作的？

无法转换为kotlin中的集合

我试图将列表转换为kotlin中的LinkedList，这里是我的代码与intellij错误 但是在Kotlin REPL，我可以做这样的事情 我的代码有什么问题？

无法更新Kotlin方法参数的值

我遵循Kotlin方法 fun getpower(base:Int,power:Int):Int { var result = 1 while(power > 0){ result = result * base power– // <—- error in this line } return result } Kotlin编译器提供以下错误Error:(6, 8) Val cannot be reassigned 更新变量有什么问题？
