我NoSuchMethodError在运行Java程序时遇到错误.怎么了,怎么解决？

我收到以下运行时错误消息(以及堆栈跟踪的第一行,指向第94行).我试图弄清楚为什么它说不存在这样的方法.

java.lang.NoSuchMethodError: 
com.sun.tools.doclets.formats.html.SubWriterHolderWriter.printDocLinkForMenu(
    ILcom/sun/javadoc/ClassDoc;Lcom/sun/javadoc/MemberDoc;
    Ljava/lang/String;Z)Ljava/lang/String;
at com.sun.tools.doclets.formats.html.AbstractExecutableMemberWriter.writeSummaryLink(
    AbstractExecutableMemberWriter.java:94)

writeSummaryLink的第94行如下所示.

问题
"ILcom"或"Z"是什么意思？
为什么括号中有四种类型(ILcom/sun/javadoc/ClassDoc; Lcom/sun/javadoc/MemberDoc; Ljava/lang/String; Z),括号后面有一个Ljava/lang/String; 当方法printDocLinkForMenu显然有五个参数？

代码详细信息
writeSummaryLink方法是:

protected void writeSummaryLink(int context, ClassDoc cd, ProgramElementDoc member) {
    ExecutableMemberDoc emd = (ExecutableMemberDoc)member;
    String name = emd.name();
    writer.strong();
    writer.printDocLinkForMenu(context, cd, (MemberDoc) emd, name, false);  // 94
    writer.strongEnd();
    writer.displayLength = name.length();
    writeParameters(emd, false);
}

这是第94行调用的方法:

public void printDocLinkForMenu(int context, ClassDoc classDoc, MemberDoc doc,
        String label, boolean strong) {
    String docLink = getDocLink(context, classDoc, doc, label, strong);
    print(deleteParameterAnchors(docLink));
}

新Java程序员在尝试运行Java程序时经常会遇到这些消息.

Error: Main method not found in class MyClass, please define the main method as:
   public static void main(String[] args)
or a JavaFX application class must extend javafx.application.Application

Error: Main method is not static in class MyClass, please define the main method as:
   public static void main(String[] args)

Error: Main method must return a value of type void in class MyClass, please
define the main method as:
   public static void main(String[] args)

java.lang.NoSuchMethodError: main
Exception in thread "main"

这是什么意思,什么可以导致它,以及应该怎么做才能解决它？

当我尝试使用Spring启动运行Spring MVC应用程序时,我遇到了异常...

构建和部署Spark应用程序时的常见问题是:

• java.lang.ClassNotFoundException.
• object x is not a member of package y 编译错误.
• java.lang.NoSuchMethodError

如何解决这些问题？

我越来越:

NoSuchMethodError: com.foo.SomeService.doSmth()Z

我是否正确理解这'Z'意味着doSmth()方法的返回类型是布尔值？如果为true,那么这种方法确实不存在,因为此方法返回一些Collection.但另一方面,如果我调用此方法,我不会将其返回值赋给任何变量.我只是这样调用这个方法:

service.doSmth();

有什么想法发生这个错误？存在所有必需的JAR文件,并且此类中的所有其他方法似乎都存在.

我正在使用Jackson示例代码反序列化POJO:

ObjectMapper m = new ObjectMapper();

该行抛出NoSuchMethodError:

Exception in thread "main" java.lang.NoSuchMethodError: org.codehaus.jackson.type.JavaType.<init>(Ljava/lang/Class;)V

我不明白

当我使用sbt运行一个spark作业时我遇到了问题,我已经完成编译,但是当我运行命令时run,我遇到了下面的问题

谁知道我该怎么办？

当ProGuard被禁用时,我的应用程序正常运行.

启用ProGuard后,应用程序将导出到apk并安装到模拟器中.

然后当我在模拟器中运行它时,强制关闭...

我正在开发一个Android应用程序并使用依赖于它的库RESTEasyClient.在运行时使用库时,我得到一个NoSuchMethodError:

java.lang.NoSuchMethodError: No direct method <init>(Ljavax/net/ssl/SSLContext;Lorg/apache/http/conn/ssl/X509HostnameVerifier;)V in class Lorg/apache/http/conn/ssl/SSLSocketFactory; or its super classes (declaration of 'org.apache.http.conn.ssl.SSLSocketFactory' appears in /system/framework/ext.jar)

                      at org.jboss.resteasy.client.jaxrs.ResteasyClientBuilder.build(ResteasyClientBuilder.java:333)

据我了解,这是因为与Android的Apache HttpClient实现不兼容.在线搜索,我发现了各种解决方案,包括org.apache.httpconnections:httpclient在gradle依赖项中,并compile.exclude module: httpclient在几个变体中添加(以解决由此产生的冲突).我已经尝试了所有这些并且总是遇到gradle或NoSuchMethodError上面提到的错误.

是否可以RESTEasyClient在Android 上成功使用？我需要采取哪些步骤才能启用此功能？
