There still is something wrong with String[] comparison when array is empty. In TopCoder Open Round 1A 250 Test #1 — "Expected output: Execution result: [] Verdict: WA " Thanks again for the plugin.

I tried to use the plugin for a codeforces contest. But when I run the code it shows the following things: Exception in thread "main" java.lang.ClassNotFoundException: net.egork.chelper.tester.Tester at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:423) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:356) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:186) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:113)

              It is still the same even after visiting that link, probably some issues with Chinesse firewall?

                  Is it same with Java 1.6? I have about the same configuration, but no warning about unused library.

    I do not know of any rule that forbids using it

    You just need first set up read/write from file (i. e. choosing custom in Inpu and Output) and thenm after testing on samples and downloading input, to run created class' main method wherever it lies (src by default)

        Input/output files should be in project root

        That is very strang you have problems with Main.java. There should be Main class inside with main method. Could you please make a screenshot?

            No need to do this for sure. I defenately do not do this, but I have separate module for Main.java

              Maybe I have to do this because the Main.class file genearted when I run the program from IntelliJ is in the output directory and my output directory is (E:/programs/Contest/out) even when I specify the output directory as "src" in the properties file ...

                That's ok — Main.class is class file, not java file, and all class files are generated in out

                  You better run Main.java from idea by, for example, right clicking on Main.java and selecting "Run 'Main.main()'"
