google-java-format
Reformats Java source code to comply with Google Java Style
google-java-format is a program that reformats Java source code to comply with Google Java Style. The formatter can act on whole files, on limited lines, on specific offsets, passing through to standard-out (default) or altered in-place. There is no configurability as to the formatter's algorithm for formatting. This is a deliberate design decision to unify our code formatting on a single format. The formatter can be used in software that generates java to output more legible java code. Just include the library in your maven/gradle/etc. configuration. A google-java-format IntelliJ plugin is available from the plugin repository. To install it, go to your IDE's settings and select the Plugins category. Click the Marketplace tab, search for the google-java-format plugin, and click the Install button. -

Joern
Open-source code analysis platform for C/C++/Java/Binary/Javascript
Joern is a platform for analyzing source code, bytecode, and binary executables. It generates code property graphs (CPGs), a graph representation of code for cross-language code analysis. Code property graphs are stored in a custom graph database. This allows code to be mined using search queries formulated in a Scala-based domain-specific query language. Joern is developed with the goal of providing a useful tool for vulnerability discovery and research in static program analysis. -

Scertify - TechDebt Community
Benchmark code quality and measure Technical Debt of projects in Sonar
Scertify™ Refactoring Assessment is an open source component dedicated to development & QA teams that provides exclusive benchmark data on Software Quality. It automatically detects the portions of an application that can be refactored, gives valuable information on refactoring strategies, and costs. Though IT departments have matured these last 10 years and have now no doubt on the benefits of a continuous control of code quality, three major concerns were still remaining, without any tools able to effectively addressing these needs: * How to understand quality indicators, and how to compare them with the state of the art? * How to measure and manage the gap between the absolute quality level of a software, and a reasonable (reachable) target of quality? * What are the shortest and safe ways to achieve your quality goals? -

DiffReport
Code Difference report
Often I have seen some Huge Maintenance Projects it is always very difficult to track the incremental files for each release and If we want to do that we need to checkout both the branches and use some UI based tool to get the diff of the files finally we end up waiting in front of the PC for a long time and do this job. In many cases we spend more than 2 hrs/day. The time increases if there are more such parallel releases and at the end of the day 1 developer does it as full time job and has zero productivity. I thought of adding value here. This just gets the diff files. Can be used for Static code analysis like PMD to do PMD only for the delta. The current status of the project is in Development". If you wish to add something please mail me. -

Web Application Protection
Tool to detect and correct vulnerabilities in PHP web applications
WAP automatic detects and corrects input validation vulnerabilities in web applications written in PHP Language (version 4.0 or higher) and with a low rate of false positives. WAP detects the following vulnerabilities: - SQL injection using MySQL, PostgreSQL and DB2 DBMS - Reflected cross-site scripting (XSS) - Stored XSS - Remote file inclusion - Local file inclusion - Directory traversal - Source code disclosure - OS command injection - PHP code injection WAP is a static analysis tool that performs taint analysis to detect vulnerabilities, tracking malicious users inputs and checking if they reach calls of sensitive functions. It has a low rate of false positives because has implemented a data mining module to predict false positives when detects vulnerabilities. The output of the tool is: - shows the vulnerabilities found and how they are corrected - new files with the corrections -

Eclipse Plug-In that determines the Minimal Access Modifier of Java types and methods project and computes the software metrics Inappropriate Generosity with Accessibility of Types (IGAT) and Inappropriate Generosity with Accessibility of Methods (IGAM). The Minimal Access Modifier of a Java type or type member is the most restrictive access modifier that is able to allow all actual usages of the particular type or member from inside a given code base (normally the entire source code of the respective Java project). The metric Inappropriate Generosity with Accessibility of Types (IGAT) indicates the proportion of those types which actual access modifier is more generous than the minimal one relative to the total number of types in a given source code subset. Analog the metric Inappropriate Generosity with Accessibility of Method (IGAM) indicates the proportion of those methods which actual access modifier is more generous than the minimal one relative to the total number of me
