Java- RuntimeException-无法编译的源代码 – 错误的树类型
我是Java的新手也是我在这个网站上的新手，所以如果错误很明显我很抱歉，但我收到了一个错误，我不知道这意味着什么，我已经尝试了一切来修复它。
我目前正在编写一个基本的应用程序库，带有一些swing接口，但问题是当试图创建一个书forms的窗口时，有相关的代码。
这是主要窗口。
public class VentanaPrincipal extends javax.swing.JFrame { public VentanaPrincipal() { initComponents(); this.setLocationRelativeTo(null); } private void bt_salirActionPerformed(java.awt.event.ActionEvent evt) { // TODO add your handling code here: EscribirBinario escritor = new EscribirBinario(); // Collections.sort(ListaClientes.clientes); if (escritor.abrir(Main.archivo1)) { for (int indice = 0; indice < ListaClientes.clientes.size(); indice++) { escritor.escribir(ListaClientes.clientes.get(indice)); } escritor.cerrar(); } System.exit(0); } private void bt_clienteActionPerformed(java.awt.event.ActionEvent evt) { MantenimientoCliente clientes = new MantenimientoCliente(this, true); clientes.setVisible(true); } private void bt_libroActionPerformed(java.awt.event.ActionEvent evt) { MantenimientoLibro book = new MantenimientoLibro(this, true); book.setVisible(true); } } 有书的forms代码。
public class MantenimientoLibro extends javax.swing.JDialog { public MantenimientoLibro() { } public MantenimientoLibro(java.awt.Frame parent, boolean modal) { super(parent, modal); initComponents(); this.setLocationRelativeTo(null); } public MantenimientoLibro(java.awt.Dialog parent, boolean modal) { super(parent, modal); initComponents(); this.setLocationRelativeTo(null); } private void bt_salirActionPerformed(java.awt.event.ActionEvent evt) { // TODO add your handling code here: this.dispose(); } private void bt_insertarActionPerformed(java.awt.event.ActionEvent evt) { // TODO add your handling code here: FormularioLibro formulario = new FormularioLibro(this, true); formulario.setVisible(true); this.dispose(); }
}
这是我得到的错误：

看看这里的错误报告 。 它有解决您的问题的方法：
From the nbusers mailing list I got the following hint: "workaround it by deselecting 'Compile On Save' in the project options".
马克在评论中指出的答案也是一致的。 这是链接： java.lang.RuntimeException：无法编译的源代码 – 什么可能导致这个？
