Question

当我尝试在Netbeans maven项目中运行文件时，它失败并跟随以下跟踪：

Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec (default-cli) on project Geodesy_Testing: Command execution failed. Process exited with an error: 1 (Exit value: 1) -> [Help 1]

我的代码中没有编译器错误或警告。

主要方法：

public static void main(String[] args) {

    boolean[] df = Utils.toBinary(17, 5);
    boolean[] ca = Utils.toBinary(3, 3);
    boolean[] icao = Utils.toBinary(0x1ab8, 24);

    boolean[] result = Utils.concatArrays(df, ca, icao); // *

    byte[] frame = Utils.booleansToBytes(result); // *

    System.out.println(Utils.bytesToString(frame));
}

当我用*注释掉行时，它运行正常。

以下是这些方法的实现：

public static byte[] booleansToBytes(boolean[] boolArr) {
    if (boolArr.length % 8 != 0) {
        throw new IllegalArgumentException("Boolean array size must be multiple of 8!");
    }
    byte[] byteArr = new byte[boolArr.length / 8];
    for (int i = 0; i < byteArr.length; i++) {
        byteArr[i] = boolsToByte(boolArr, 8 * i);
    }
    return byteArr;
}

public static boolean[] concatArrays(boolean[]... arrays) {
    boolean[] result = null;
    int offset = 0;
    for (int i = 0; i < arrays.length; i++) {
        if (i == 0) {
            result = Arrays.copyOf(arrays[i], arrays[i].length);
        } else {
            System.arraycopy(arrays[i], 0, result, offset, arrays[i].length);
        }
        offset += arrays[i].length;
    }
    return result;
}

知道了。忘了关掉-X＆amp;没有注意到更重要的痕迹。

Maven无法运行该文件（LifecycleExecutionException）
