源代码：

<html>
<body>
<form action="welcome.php" method="post">
Name: <input type="text" name="name" />
Age: <input type="text" name="age" />
<input type="submit" />
</form>
</body>
</html>


<?php
echo date("Y/m/d");
echo "<br />";
echo date("Y.m.d");
echo "<br />";
echo date("Y-m-d");
?>

警告：

Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone.

原因：

通过搜索，发现从php5.3 ，当对使用date()等函数时，如果timezone设置不正确，在每一次调用时间函数时,都会产生E_NOTICE 或者 E_WARNING 信息。知道了问题的根源，解决的方法有三种，任选一种即可。
一、在页头使用date_default_timezone_set()设置 date_default_timezone_set(‘PRC’);
二、在页头使用ini_set(‘date.timezone’,'Asia/Shanghai’);
三、修改php.ini。打开php5.ini查找date.timezone 去掉前面的分号修改成为：date.timezone =PRC
注意：上述设置都是针对中国大陆来设置的，同时PRC也可以用Asia/Shanghai，Asia/Chongqing，Asia/Urumqi来代替。

这篇文章主要介绍了解决php的“It is not safe to rely on the system’s timezone settings”问题的方法，需要的朋友可以参考下 如果使用PHP5.3以上版本时，如果没有正确的配置php.ini就会出现PHP日期函数的错误。以前很多旧的PHP编程教程没有说到这个问题，所以不少读者会觉得困惑，下面笔者为大家讲述解决这个问题的三种方法。 "
翻译： Of course. After reviewing your Gradle files, it's clear the main problem is not a single error but a mix of structural issues, outdated practices, and critical typos. Your build script merges settings that should be in separate files and uses fragile methods that will cause constant problems. Here is a breakdown of the issues and a step-by-step guide to fix them. ----- ### \#\# 1. Critical Errors That Will Break the Build These issues need to be fixed first, as they will prevent Gradle from running correctly. #### **A. Typo in `targetSdk`** In your module's `build.gradle`, you have a typo. * **Problem:** `targetsdk 34` * **Fix:** It should be `targetSdk` (with a capital 'S'). <!-- end list --> ```groovy // In your module's build.gradle defaultConfig { minSdk 29 targetSdk 34 // FIX: Was 'targetsdk' } ``` #### **B. Typo in JaCoCo Configuration** In your `createOfflineTestCoverageReport` task, you have a typo in the word "configurations". * **Problem:** `classpath: configur3+ations.jacocoAnt.asPath` * **Fix:** It should be `configurations.jacocoAnt.asPath`. <!-- end list --> ```groovy // In your JaCoCo task ant.taskdef(name: 'report', classname: 'org.jacoco.ant.ReportTask', classpath: configurations.jacocoAnt.asPath) // FIX: Was 'configur3+ations' ``` ----- ### \#\# 2. Major Structural Problems Your project's build logic is incorrectly structured. You've mixed settings for the root project and the `model_base` module into one file. #### **A. Root Project and Module Logic are Mixed** You should have at least two `build.gradle` files: one in the project's root directory and one inside your `model_base` module. * **Project Root `build.gradle` or `build.gradle.kts`:** Should contain `buildscript` settings (like the Android Gradle Plugin version) and `allprojects` repository settings. It should **not** contain `apply plugin: 'com.android.library'` or Android-specific settings like `compileSdk`. * **Module `app/build.gradle` or `library/build.gradle.kts`:** Should contain `plugins { id 'com.android.library' }`, the `android { ... }` block, and the `dependencies { ... }` for that specific module. #### **B. Action Plan: Restructure Your Files** **Step 1: Create a `settings.gradle` file in your project root** (if you don't have one). It tells Gradle which modules are part of your project. ```groovy // settings.gradle include ':model_base' // include ':app' // if you have an app module ``` **Step 2: Clean up your Root `build.gradle` file.** It should only contain build-wide information. ```groovy // Project Root: build.gradle // The buildscript block is an older pattern, but if you keep it: buildscript { repositories { google() mavenCentral() } dependencies { // Use a consistent version for AGP classpath 'com.android.tools.build:gradle:8.1.0' // You don't need JaCoCo here; the plugin handles it. } } allprojects { repositories { google() mavenCentral() maven { url "https://jitpack.io" } } } ``` **Step 3: Create/Fix your Module `model_base/build.gradle` file.** This is where most of your current code should go. ```groovy // Module: model_base/build.gradle // Use the plugins block at the top plugins { id 'com.android.library' id 'jacoco' // Apply jacoco plugin here } android { namespace 'com.st.model_base' compileSdk 34 defaultConfig { minSdk 29 targetSdk 34 // Corrected typo } // ... your other android settings } dependencies { // ... your dependencies implementation 'androidx.appcompat:appcompat:1.6.1' // Updated version } // ... your JaCoCo tasks and configuration ``` ----- ### \#\# 3. Bad Practices and Recommendations These are issues that make your build slow, fragile, and hard to maintain. #### **A. Manual `bootstrapClasspath` Manipulation is Very Bad** Your use of `options.compilerArgs << '-Xbootclasspath/p:...'` and manually rebuilding the `bootstrapClasspath` to include `framework.jar` is an extremely fragile and outdated practice. * **Why it's bad:** It overrides the standard Android compile environment. It can break with any update to AGP, Gradle, or Java. It makes your build completely dependent on a local JAR file. * **Recommendation:** **Remove all three `gradle.projectsEvaluated` blocks.** Rely on the `compileSdk 34` to provide the Android APIs. If you absolutely need APIs not available in the public SDK, this approach is still not recommended and indicates a potential design flaw. #### **B. `dependsOn(clean)` is an Anti-Pattern** Your line `createOfflineTestCoverageReport.dependsOn(clean)` is very inefficient. * **Why it's bad:** It forces a complete project clean and recompile **every time** you want to generate a report. This will make your build process incredibly slow. * **Recommendation:** **Delete this line.** Gradle's tasks are designed to be incremental. #### **C. Redundant Configurations** You have multiple `tasks.withType(Test)` and `gradle.projectsEvaluated` blocks. This makes the script confusing. * **Recommendation:** Combine them into single blocks to avoid conflicts and make the logic clear. #### **D. Outdated Dependencies and Repositories** * **JCenter is Deprecated:** Remove `jcenter()` from your repositories. It was shut down years ago and can slow down your build as Gradle tries to connect to it. `mavenCentral()` has replaced it. * **Old AppCompat Library:** `androidx.appcompat:appcompat:1.4.1` is old for `compileSdk 34`. Update it to a more recent version like `1.6.1` to avoid potential incompatibilities.

* **修复：** 应该为 `targetSdk`（注意大写 'S'）。 ```groovy // 在你的模块 build.gradle 中 defaultConfig { minSdk 29 targetSdk 34 // 修复：原为 'targetsdk' } ``` #### **B. JaCoCo 配置中的拼写错误*...
